I Hate This Place Kellerpils Recipe

Living in a town called Keller, I thought it made sense to try brewing a beer in the technique of the same name. "Keller" is German for "cellar" and refer to beers that have been lagered. However, the term is not generally used for modern lagers, rather it is generally used along with "zwickel" to identify beers that are unfiltered and unpasteurized, leaving behind a beer that has naturally clarified by lagering but not filtered or fined like modern lager styles. Kellerbier is generally served on a gravity pour from a lined barrel, not too different from English cask ale. It's fairly clear, since it undergoes some lagering, but lacks the clarity of filtered lagered. Like cask ale, it is low in carbonation because it is traditionally aged in unbunged casks so no carbonation forms. However, you may find some served with a cask-like level of carbonation, particularly those given the zwickel name.

Kellerbier has been adopted as a particular style of (flavor) hoppy and orange-ish German beer that is unfiltered; however, I am using the term "keller" in reference to the technique of creating a lager-like beer without filtration and served by cask. The base beer for this particular recipe is a bohemian pilsner rather than what has been deemed kellerbier as a specific style. It is an untraditional marriage of a non-German lager style with German verbiage. I am not creating a kellerbier, merely a bopils brewed and served using keller technique. This recipe is an adaptation of the kellerpils recipe from Victory in For the Love of Hops.

Although this beer was designed with the keller serving method in mind, it's a fairly straightforward pilsner recipe that could be adopted for bottling or kegging. It's a bohemian pilsner recipe at its heart but I've adopted a little German influence with some first wort hopping and a newer noble-like variety for the big hop finish at knockout. So it's also a little all-over-the-place. Maybe calling it "fairyly straightforward" is incorrect. However, this recipe is 100% pilsner malt. There are lots of pilsner recipes out there with munich malt, melanoidin malt and even old 1990s recipes with crystal malt out there. I prefer my pilsners a little drier and to develop those melanoidins through a decoction mash rather than specialty malt.

The danger in using straight pilsner malt is that the malt flavor in the beer can be very one note so I've combined two different pilsner malts from two different parts of the world. Here I have blended American and Belgian pils. I admit that's unconventional for a bopils. I wanted to get some floor malted pils and mix it with another variety but I couldn't find the floor malted in stock at the time I bought my grain for the year (it seems to come and go at various shops) and took what I could get. It will certainly be an interesting experiment.

Kellerbier is most commonly served out of a gravity keg but I am going to employ my free party pig, sans pressure pouch, to accomplish roughly the same technique that I have used to treat the party pig as a cask for English/American beer styles but leave out the regulator piece and carbonate it down to around one volume so it will pour easily. Plus, a little priming will help consume the oxygen trapped in the pig during packaging so that will help the beer stay fresh while it ages. I hope to be drinking this end of July or early August, right at the midpoint of our ridiculously hot summers.

Last note before getting into the recipe: I said above that I live in Keller, Texas. I hate living here and frequently tell people that. The name of the beer is meant to impugn the city's good name rather than honor it by brewing a beer in the technique of the name. Suck it, Keller. The long term plan is to move to Denver but financially we have to stay put for a while.
