Diabeetus Juice barrel aged imperial stout recipe

Does the world need more barrel aged imperial stout? I suppose it does if I need to pull out the whiskey character out of this whiskey barrel I bought. This barrel is a mere two gallon barrel from a young distillery near Dallas that produces a wheat whiskey and vodka. It's a solid barrel; not one of the thin barrels retailed to bars and consumers to age cocktails and spirits countertop. The long term plan is to use the barrel for aging sour beer but it needs at least a couple runs of clean beer to strip out most of the liquor and more assertive oak character. Imperial stout is a good first run because it's heavy flavors hold up.

My goal with this imperial stout is to balance the extreme attributes of the beer. I quickly tire drinking the super sweet, diabetes juice BA imperial stouts that are all the rage right now. I like the more bitter chocolate and coffee flavors over fudge and Starbucks mocha found in the sweeter variants that goes overboard in sweetness with the oak and whiskey draped assertively on top. I want the oak and whiskey present but just as I like the sweetness under control I don't want the stout to taste like a cocktail. So this recipe is lots of roasted malts and sits on the lower end of the ABV for the style so it further attenuates. 

But first, the barrel needs preparation.

Preparing the whiskey barrel

Soaking the barrel in water
Due to the size of the barrel and my plan to put to use for sour beer I needed to prepare it appropriately. That means prepare it initially for any kind of beer and second to restrict oxygen ingress. 

The distiller told me he emptied the barrel about two months prior and it probably didn't need to be soaked to swell the staves but I didn't want to take a chance. I gave it a quick soak to the heads for four hours on each side. The result, a nicely soaked barrel. I let it dry out on the exterior for a few days so I can wax it.

Once the barrel was dry on the outside I set out to wax it. Like many homebrewers I opted for the cheap route of parrafin wax. The wax melts down easily on the stove and I painted it on with a paintbrush after using masking tape to block off the portion I wanted unwaxed.

Given the small size of the barrel I knew I needed to wax most of the barrel to properly regulate air ingress. I don't find a compelling reason to allow even more airflow into the beer just because it's in a barrel. The barrel wax calculator here affirmed my idea. I ended up waxing the entire barrel minus a square around the bung hole.

I thought I had some pictures after waxing but I guess I didn't take any. It's sort of a messy look because I didn't flame the wax to melt in down. I might do that after the barrel is full. Putting a flame to a sealed cask full of alcohol vapors seems like a really dangerous thing.

The picture to the left is the barrel after waxing and wrapped in saran wrap. I wrapped it in saran wrap for a couple reasons. First, if it managed to leak after swelling and waxing the saran wrap would help keep a leak from turning into a mess too quickly. Second, the wax is crumbly and the saran wrap would help keep that from making a mess while moving the barrel around. I don't expect it to add any oxygen barrier nor do I think it is necessary beyond the wax.

I don't have a stand for the barrel but it sits comfortably on a folded bath towel. I added a rolled towel on each side on the counter to keep it from rolling over. It's janky and looks janky but I'll worry about finding a nicer support after I move it to a permanent location.

Bottled 2.24.17. Tasted two days ago and it was lightly barrel-y with a strong vanilla flavor. Let it ride and tasted today. Firm whisky/barrel flavor without being overwhelming. Another day and it's probably undrinkable. Tastes firmly of whisky, coffee and chocolate. Very happy with this. After racking out sent an adambier into the barrel.

Bottled with 2oz table sugar and added KV-1116 to bottles to ensure timely carbonation.

Robot Geisha Belgian Pale Ale Review

This is a long delayed review on this beer with the tasting notes flowing from early bottles on both the version with and without the Ethiopian coffee. This Belgian pale ale was primarily an experiment on multiple fronts:

  • Putting to use the jarrylo hops that have sadly sat in my freezer for too long;
  • Seeing what a light roasted coffee would bring to a beer;
  • Checking out how a Belgian pale ale would taste with a fruitier hop profile more in line with popular American pale ales than the typical Belgian pale ale with more restrained hop character;
  • Keeping my culture of WY1214 going.
So let's see how I did.

Robot Geisha Belgian Pale Ale (no coffee)

Appearance: Predictable copper color one expects in a pale ale. Slight haze. Head is huge, slightly off white with big, rocky bubbles. The head hangs around to the end of the glass with sticky lacing. It isn't the prettiest lacing, like Duvel, but leaves behind a huge archipelago of lacing.

Aroma: Mellow fruit is first to arrive but doesn't go on the attack like an American pale ale. The banana is there along with an Orange Julius-like orange aroma followed by honeydew, pear, lemon and strawberry. There's a little pepper in the finish if you're looking for it. Very little grain aroma but it has a lot of competition.

Flavor: Like the aroma the hops are first to strike. Banana is more prominent and slightly more banana candy than real banana. Orange is next with a really sweet and smooth orange flavor, like orange creamsicle. Melon salad, lemon, pear. Just a hint of grassiness that acts as a bridge between the fruity hop flavors and the rest of the beer. Grain hits in the middle with wheat bread, caramel and a touch of honey. The yeast make an appearance at the end with some pepper and clove. As a whole, it's kind of like your mom gave you a piece of really soft wheat bread with Dole fruit cocktail--minus the cherry--poured on top. But less sweet.

Mouthfeel: Moderate body a touch thicker than really dry west coast pale ales. The finish turns really dry which helps evade the sweet fruit flavors from giving the beer illusion of a heavier body. 

Overall: I was led to believe the jarrylo hops would be all fake, plastic-y banana. I was pleasantly surprised to find very little of that here--although there was some. (As the hops faded in the bottles over months the fake banana dropped off and very little banana flavor remained. The orange marmalade flavor of triple perle remained.) This beer was better than expectations but not necessarily something I would be wowed by ordering blind. I wasn't in love with the jarrylo hops and wouldn't acquire more but the beer itself could easily be a good base for a nice Belgian pale ale or saison either with a different hop or adjusting the other hops to accommodate for its absence. 

Robot Geisha Belgian Pale Ale with Ethiopian Natural Processed Coffee

Appearance: Same appearance as the coffee-free portion with a slight haze.

Aroma: Similar aromas with a soft mixed berry aroma in the mix. Aromas are less distinct and the grain-based aromas are slightly more prominent.

Flavor: Like the aroma, the same flavors are present but less distinct. Citrus outweighs the softer fruit flavors from the hops. Under the fruit cuts a smooth coffee flavor and an earthy blueberry flavor not unlike mosaic hops. There is tartness at the end provided by acids from the coffee.

Mouthfeel: Slightly heavier than the non-coffee portion with slight prickly acidity.

Overall: An interesting but not preferred beer. The coffee flavor is nice and adds an interesting element to the flavor profile. The problem is the acidity in the coffee. It's not a strong acidity in the flavor but the change to ph definitely mutes a lot of delicate flavors. A washed Ethiopian coffee would have been a better choice for this beer. A natural processed coffee might sit better in a sour beer where the acidity would add acid complexity.

Ground Cherry Pale Sour Recipe

Here's a sour beer I've wanted to brew for the past three or so years. It harkens back to a time where I was more enamored with the idea of brewing sour beer with fruit and especially fruit that didn't come from generic supermarket varieties. That's a problem because I'm a terrible gardener and to procure enough fruit for beer requires a bush or tree that would require years of development. I went on the hunt for fruit that would survive Texas summers without too much coddling and wouldn't require years of development before I could even get close to fruit.

What I found was something called a ground cherry.

WTF is a ground cherry?

Ground cherry is a small fruiting plant similar to a tomatillo. It grows like a tomatillo plant and develops small fruit that grow in husks, like a tomatillo. There are a few varieties around the world but the two most common are Aunt Molly (which have a citrus-y flavor) and Cossack Pineapple (you can figure that out). It's most similar to a gooseberry in both appearance and flavor, although it is less acidic (and not actually a gooseberry).

Picture of the plants--not mine
It grows across a wide range of environments. With some watering it survives into the triple digits during summer and hangs on until temperatures drop to 40F like tomatillos and tomatoes. The plant gains its name from the way the fruit grows and drops. Midway through maturity the stem supporting the husked fruit gives and the fruit drops to the ground. It takes an additional few weeks for the fruit inside to reach maturity. The green half-mature fruit is full of solanine, which is the poisonous compound in tomato plants and other related plants. This goes away as the fruit matures into a brighter color, orange for Aunt Molly and goldenrod yellow for Cossack Pineapple.

The fruit is interesting for sure. I opted for the Cossack Pineapple, which at full ripeness has a pineapple and vanilla flavor with a hint of tomatillo. When it's still a little green the vanilla is less present with more of a pineapple-tomatillo-green tomato flavor. Culinary applications range from use like tomatoes or tomatillos in salsas or salads to berry-like applications like pies and tarts.

The fruit grow to between green pea and marble size; that means to procure a decent volume of fruit you need a lot. The good news is that this plant has a high yield of fruit, even with moderate growth. The challenge is that it grows and drops fruit the entire growing season which means collecting fruit and probably freezing to get a decent yield. It's taken two years to collect one pound but that is one plant the first year and two plants the second year, minus the volume I ate instead of setting aside for beer. To obtain enough in a single year for a five gallon batch I would need several healthy plants and keep from eating too many. 

The inside of the fruit contains a lot of seeds which may be an issue for beer. I'm slightly concerned that the seeds risk bleeding excessive tannins into the beer. I could try pureeing the fruit but I'm concerned that will tear up the seeds and straining them out would be an absolute PITA. Instead I plan on giving the fruit some pulsed chops in the food processor to break them apart and then plan to avoid long contact time with the sour beer.

Ground Cherry Sour Beer Recipe Design

Nothing to exciting about the recipe design. I wanted to keep the beer pale and fairly neutral to let the fruit flavors shine. While some fruit play nicely with darker sour beers, the flavors of these ground cherries are more compatible with the flavor profile of a pale sour beer with little to no specialty malt. 

I am also still trying to use ingredients on hand so the grain bill was mostly built out of a "what can I sling together to get in the vicinity of what I need to brew" than trying to craft the perfect recipe. I have a clump of white wheat malt which will make up the bulk of the grain bill. Of all the beers I've had with a strong pineapple flavor, they all seem to have a large portion of wheat so I felt this was a good fit. The rest of the recipe is designed to keep on the path of a lighter beer with low IBUs and only a little munich malt to add a little maltiness around the pineapple and vanilla flavors.

Lambic Solera Part Twenty-Three: Bottling Year Six, Blending Gueuze 2

It took me two months to sit down and write this post because writing it meant accepting a seven year old brewing process had officially ended. I brewed the first batch of this solera in December 2010 after taking my last law school final for the semester. It was older than my marriage, older than my law license and older than most of my friends' kids. I don't know if it's the longest continuous solera on the homebrewing level but it was probably one of the oldest. (Undoubtedly surpassed at some point in the future with the growing number of excellent sour homebrewers.) My lambic solera taught me a lot about brewing sour beer over its six years which produced six annual bottlings, two fruited bottlings and two blended gueuzes for a total of about twenty-two gallons of lambic (or lambic-inspired beer...whatever).

It was a difficult decision to end the solera. The lambic coming out of the solera had reached a great plateau and I chose to stop the solera by choice rather than because the quality had declined to a point where I had to. Ideally I would have kept the solera going for as long as it continued to produce great beer but as I've mentioned before my wife and I are moving to Denver next year and I need to wind down beer production. In Denver I will probably eschew starting a similar solera. Not because I didn't like it but because I want to make room for some other brewing projects. I still want to set up my sour blending project and I want to play with spontaneous fermentation. Those will take up a fair amount of space and produce a good amount of beer. I also have acquired a small barrel (posts on that coming soon) so that's more sour beer to brew.

For today's post I'm just going to discuss bottling Year Six and Gueuze 2 along with my initial impressions of the beer. I'll follow this up soon with a much longer post discussing all the important lessons I learned along the way with the lambic solera. The final post will be tasting notes on Year Six and Gueuze 2 later in the year which will be the final post on the lambic solera.

Bottling Year Six

The carboy of Year Six looks right in line with previous years, particularly those with the slightly darker red wheat rather than white wheat. In the picture below of all three vessels you can see the six gallon Better Bottle with Year Six next to Year Five (which had some white wheat) and Year Four. The vessels are dusty as hell--that's because they age next to cat litter. Much funk to be had. ZFG.

Like Year Five and Four, which were turbid mashed, I felt like the beer was somewhat unfinished after a year. The turbid mash really seems to stretch out smoothing out the flavors in young brett fermentations I really dislike (hot trash, muddiness). I expect, like it's two older siblings, it will break stride somewhere around August.

The flavor is a little unfinished due to the age but one thing that stuck out to me was that it seemed fruitier than previous beers. In the finish I thought it had a brandy-like flavor. Then I remembered I had added brandy along with the oak cubes on this batch. It's definitely the most aggressive addition of spirits or wine among the six years. It's wonderful but definitely adds a different dynamic.

Like each of its predecessors this lambic (or lambic-inspired beer, if that chills your heckles) was mostly bottled in 750ml champagne-style bottles with the remainder going into other thick walled bottles. I bottled it with one ounce per gallon of table sugar as I have in the past which seems to shoot a little low on carbonation but I felt like consistency prevailed over risking some overcarbonation. Approximately four gallons were bottled straight as Year Six.

As an aside, have you ever thought about how awful it would be to try to clean seven year old krausen out of a Better Bottle?

I cleaned out the trub every other year of the solera but never tried to clean out the trub because, well, I wasn't sure how and I wasn't sure if I could do so without risking causing an unwelcome infection or introducing unwelcome flavors from a cleaning agent. So I just left it and kept refilling wort. You can kinda see in the picture to the right I cleaned the Better Bottle pretty well and yet that krausen didn't budge.

Filling with moderately hot water and oxyclean for several days and repeated scrubbing with a bottle brush eventually got most of it out. Not sure I got enough out that I would ferment clean beers in it but enough that I feel safe fermenting sour beer without the remnants of the lambic solera krausen overtaking the culture added with new wort.

Blending Gueuze 2

Normally I am a solid proponent of blending to taste rather than blending everything you have because you don't want leftover beer. That's not what I did here. Like Gueuze 1, I decided to let the lambic solera and each of its vintages be what they were and blend the gueuze with all the beer it had to offer. That meant creating a blend of 50% Year Six, 25% Year Five and 25% Year Four. 

Year Four and Five from the solera taste well into their age with flavors similar to their bottles but a little more mellow, probably from slightly more oxygen exposure through the airlocks and silicone stoppers than the bottle caps. (In the picture, Year Five is on the left, Year Four on the right.) There is a noticeable color difference. Some of that is age but some of it is a difference in wheat. Year Five is mostly white wheat while Four, like Six, are more red wheat. I definitely feel the red wheat brings more wheat flavor, which I like. 

My initial impression of the blend is promising. The brandy flavor of Year Six definitely appears but far more subdued than Year Six on its own. It works in the mix. The flavor is deep with funk, lemon, hay, gentle phenolic spice, honey of well-aged beer but also prickly with young acidity. It is more complex than Gueuze 1 and I suspect the aged hops drive that complexity even more than the turbid mash. Like its components, I expect this beer will hit its stride in eight or so months. 

Finishing bottling the solera

Ended up with a lot of bottles. Year Six on the left, Gueuze 2 on the right.

So from here I expect to have tasting notes around August when the beers are in their prime. I cracked open one bottle of Year Six with the Super Bowl, as I do every year with each vintage, and it is promising but definitely still needs some time to smooth out its rough edges. The brandy was more subdued with some carbonation and I think it will be just fine in the end. 

Next post will be an assemblage of thoughts on the solera process, brewing lambic-style within a solera, what I thought about the changes I made each year and some other general thoughts I've been mulling for the past seven years.

One Gallon Spontaneous Fermentation #2: January 2017

This batch will follow the same technique as the previous turbid mash/spontaneous fermentation batch brewed in November 2016 with a little adjustment to the hops due to inventory and adding oak. I had hoped to brew another one gallon batch last month but we haven't had a consistently cold winter where I could find time to brew and it would be within the right temperature range. We have a cold streak so it's as good of a time as any to brew more beer. As this batch will closely follow the last batch's recipe I won't waste space duplicating the recipe. I'll just note the changes and use this post to track the batch from brewday through fermentation and aging.

Changes from Batch 1 to Batch 2 of One Gallon Spontaneous Fermentation Recipe

Two small changes to the recipe: (1) adjusting hops to the aged hops on hand; and (2) adding oak. The oak addition will be light. Three medium char oak cubes are steamed in the microwave to remove some of the fresh oak flavor. I find this is about the right amount to gain minimal oak flavor and a good balance of tannins. 

A lot of aged hops for one gallon
Hops will include a blend of 2011 Belma, like batch 1, and a mix of 2014 Cascade and Mount Hood from my garden. I wish I could say I had some better explanation for the combination of aged hops but there it is. I had less of the 2014 mix than I thought. I had 0.25oz of the 2014 Cascade/Mount Hood blend. I added 0.25oz of 2011 Belma. I'm only using 0.50 oz of aged hops for this batch because I fear the Belma may still have too much alpha acid left behind.

Brewday & Fermentation Notes

Brewed 1.5.17.

Sent outside at 4:28pm. Transferred to heated cooler at 5pm. Realized the volume was significantly low at this point and added waves of hot distilled water from 5-5:30pm to get up to one gallon of wort. This explains the variance at the 5:30pm reading. I added about a third of a gallon of water so clearly my boil off calculation was way off.

Day ended up colder and windier than expected but even with approximately ten degrees cooler ambient temperatures the wort was only a handful of degrees below what batch one's warmer evening produced at similar intervals. Here's the cooling:

Time                            Ambient             Wort

Fermentation Notes

2.14.17: Gave a quick taste. Tastes very similar to other wild/spontaneous cultures. Muddled estery profile with banana, melon, cherry, strawberry, peach. Muddled bottom end with musty, generic phenolic spice. Slightly mushroom-y. Apple juice-y. Still fairly sweet and thick like a hefeweizen with a big sweet orange slice. Not far from the batch coolshipped in November 2016 but less bitter, likely due to dialing back the hopping rate.

Just the Tip -- Mixed Fermentation Saison with Fir Tips

Here's another rummage-around-the-house foraging beer. In December I helped my wife and her family pick out a Christmas tree. As we were unloading it from the car I noticed all the young tips at the end of the branches. I pulled one off and rubbed it between my fingers. It has that citrusy aroma one expects in the greener, bushier tips on a spruce or fir tree but also the woody, spruce-like aroma of the wood. Reminded me a lot of chinook hops. I immediately thought, "I could put this in beer." After unwrapping gifts on Christmas I asked if I could trim off all the tips for beer. I was approved and hacked up the tree. After trimming as much of the tips as I could without knocking off ornaments I ended up with approximately half an ounce of fir tips.

I settled on shoving these fir tips into a mixed fermentation saison. Initially I resisted the idea of treating another saison as a dumping ground for weird ingredients but a couple reasons justified the decision. First, I need to further explore my mixed farmhouse culture and this is a good opportunity to see how it plays with other flavors. Second, that woods/citrus/resin flavor is not entirely out of place for the style, especially within the realm of the more unusual Fantome offerings. Additionally, later on that day I visited my parents who it turns out grow Meyer lemons and gave me a large bag. I want to brew another saison with the lemons and blend at least some of each of these beers. (More on the Meyer lemon beer in another post.) 

Designing the Saison with Fir Tips recipe

Normally spruce tips or fir tree tips are harvested for beer in the spring when they are bushy and green with a flavor that leans more citrus than woodsy. I get that this is the "wrong" way to do this. This is purely an experiment for the sake of experimenting. I smelled the tips on the Christmas tree, liked what I smelled and decided to see what happens. 

I want the recipe to be fairly basic so the fir tips do not fight too many other flavors. The grain bill is a very simple 75% pale malt/25% unmalted wheat grist. Hops are minimal with a charge of Opal in the whirlpool with the fir tips. Opal has a earthy flavor that I expect will round out the fir tips just a little. My initial run with this mixed saison culture is very fruity in an overripe berry flavor. I'm not entirely sure how that will mix with the fir tips but it's just a gallon of beer. If it sucks it can flush out my kitchen sink drain.

1.26.17: After what seemed like a month of fermentation things appear to have tapered off. A slight taste is the emergence of the fruity yeast profile with what I assume is the fir tips in a herbal, forest-y flavor that is far less aggressive than pre-fermentation. Very oily and slightly tongue numbing--hope that is excess oils pulled from sampling from the top of the beer.

3.31.17: Gave the beer another taste today. Beer is dry with a nice range of fruity flavors, moderate herbal flavor and a twinge of brett on the end. Far less tongue numbing sensation but slight remnant. Will probably let it go another three or four weeks to mature before bottling.

A 2016 Attempt at Spontaneous Fermentation

Winter has finally shown up with an end to 70F+ November days. Nights finally drop into the thirties which is a good range for throwing out a coolship. So far I haven't had good luck with attempts at spontaneous fermentations but I will take blame for those misfires. Some were experiments of just leaving wort out to see what happens. Then there was the batch two years ago that I cooled too fast and ended up with a poorly attenuated and bland. In between that time and today a lot of great information is available about the mechanics of coolships and spontaneous fermentation (largely thanks to Milk the Funk) that hopefully will help get something at least drinkable.

Tackling spontaneous fermentation is a big goal for my homebrewing. I am very happy with the results of my other mixed fermentation beers, both using lab blends and blends of dregs. Spontaneous fermentation carries such an allure as an interesting process and cool factor (pun not intended) that I can't resist.

What I don't want to do is keep throwing five gallon batches at the process to get it right. I mean, I should, but I don't have the space for that many carboys to see how they pan out. Plus, that would means blending even larger volumes and that's just more than I am prepared to tackle. So one part of my continued experimentation is seeing if it is possible to effectively coolship smaller volumes. It would be a lot easier to manage a full spontaneous fermentation project (dare we call it lambic??) in one gallon increments instead of five to ten. The obvious problem is that smaller volumes cool faster than larger volumes of wort and the cooling rate affects the mixture of yeast and bacteria. Adjusting the surface area to slow cooling rates risks reducing innoculation rates which diminishes the biological diversity. So that is an issue. 

Attempted technique to coolship one gallon of wort

Using the information on the MTF Wiki on coolships I worked out some numbers to try to get this even close to a range that makes sense. As the wiki explains, one of the big problems on a homebrew scale is the dimensions of many commonly used vessels play against our favor by allowing cooling to occur too fast with too little innoculation. Kettles are often a great option because the geometry more closely matches commercial-sized coolships.

For one gallon batches I typically use my five gallon kettle which doesn't work here as a very good coolship. The size of the kettle is good but with so little liquid inside the liquid dimensions change to favoring a large surface to volume ratio that is good for innoculation but bad for controlled cooling. I also worry that the distance between liquid surface and the top of the kettle may act as a shield from inviting the right guests.

My solution for this problem is to transfer the wort to a six quart stock pot from the kitchen. The dimensions more closely align with a normal brewing kettle full of wort and the metal is thicker which will help retain heat slightly better. I'll also wrap it with towels to help insulate and slow cooling.

I am still concerned the cooling will go too quickly in the stock pot, especially through the 140-60F range where the good inoculation happens. To cure that problem I will transfer the wort to my two gallon cooler mash tun because it has superior insulation. The liquid dimensions will be about the same so it's all upside. I'll preheat the mash tun to avoid temperature loss through the transfer.

Quick note on the recipe

For this recipe I will follow fairly typical lambic wort production technique. The biggest exception will be using pale malt rather than pils malt merely because I am trying to work through the sack of pale malt in the house. Hours of turbid mash fun. The only suitable aged hops I have on hand are from my homegrown hops. Most of my older hops are cascades which are a little higher in alpha acids than typical lambic hops but not so high I think it will be a problem.

Brewday and Fermentation Notes

Brewed 11.19.16

Preboil volume: 2 gal
Preboil gravity: 1.028
Mash efficiency: 78%

Hops: 0.55 oz mixed 2014 cascade and mt. hood from garden plus 0.15 oz 2011 belma

Recorded temperatures for several hours roughly every thirty minutes. Did not expect to drop temperature so quickly. Transferred to cooler after one hour (11pm). Preheated cooler with approximately one gallon of water at 160F and sat in the cooler for ten minutes. Water dropped to 144F before dumping.

Sent outside at 9:55pm, brought in at 9:30am the following morning. Temperatures dipped in the very early morning to mid-30s so the wort probably got down to similar temperatures before the sun came up and started to warm. I went to bed around 2:30 so that's why readings stopped.

Temperatures were consistently dropping by four degrees once the ambient temperature held constant at 37F and the wort temperature coasted into the mid-eighties. Projecting that data forward the wort likely hit the mid to upper thirties sometime around 6:00am. Cooling is not linear so it possible the cooling slowed later in the night to less than eight degrees per hour and the wort never dropped below the final reading the following morning at 47F.

Fermentation Updates

Within five days active fermentation appeared with fluffy white krausen. Went away after a few days. Approximately a week later the same thing happened. 

12.19.16: Thirty days out tasted the beer. Sweet-sour. Bitterness is prevalent, somewhere between APA and IPA. Mildly phenolic. Lingering mushroom flavor. Tastes similar to other wild yeast cultures. So far none of the weird clumps that plagued my last attempt at a spontaneous fermentation

Tropic Bling 2.0 Tasting Notes

This beer was my first run of my mixed saison culture including a particularly wonderful bottle of Fantome, Logsdon Seizoen, Perennial Aria and St. Somewhere Saison Athene. After putting together these dregs and working them up in a starter I needed somewhere for them to go. I had the grain bill and hops for a clone of Funkwerks Tropic King I needed to use so it became the first attempt with this mixed saison culture. Anyway, here comes dat review.

Appearance: Pours penny copper with a tapioca off-white head that explodes upwards from the glass on first pour but descends into a weak, thin head. It's slightly hazy with an oily appearance on the surface.

Aroma: Overripe strawberry, lime and stale bread wrapped up in hay and wet newspaper thrown in a barn for a week. Subtle hints of black pepper, lemon, bread crust and a slightly meaty aroma like corned beef? Overall, very much an overripe fruit salad with some clear brett funk. The fantome strawberry ghost flavor is all over. 

Flavor: Overripe mixed berries, lime juice, excessive black pepper, hay, cardamom, mace, musty basement, apricot, cherry, wheat bread crust, sweet malt, typical brett barnyard funk. A hint of floral hoppiness. The flavor is heavily overripe berry and acidic fruit that the grain is lost. It has an amorphous sweetness from the munich malt that feels almost overbearing with the sweet, overripe fruit flavors.

Mouthfeel: At once it feels on one hand sweet, heavy and slightly oily while on the other hand dry, slightly bitter with a black pepper spice like french fries with too much black pepper. It's spritzy which helps bigly keep the oiliness from feeling dense on the tongue. It's a strange mixture of textures. The mouthfeel is the weakest part of the beer. The oiliness is something I've experienced before with brett beers. It's probably my least favorite brett attribute. Fortunately, it normally goes away with time.

Overall: An interesting beer. It has wisps of Funkwerks' version but the heavy fruit tones take it somewhere very different. The pepper notes must be an issue with brett and rakau hops because the same thing existed in the older version I brewed with a different mixed culture. I like this beer a little more than the Funkwerks beer but it isn't my favorite. It's too sweet for my preferences. I hope the oily texture breaks down. This tasting is seven months out. A younger bottle had as much of an overripe fruit flavor but seemed jumbled. Maybe this mixed culture just needs a lot of time. Not necessarily a bad thing if I can even get near that Fantome magic.
