Spontaneous Fermentation Project Part 7 -- week 4 of fermentation

This week will roll the beer through a month of its journey. Interesting things are going on, although I don't know what exactly is going on, so it's worthwhile to keep recording this journey on a daily basis.

Day 22

You can see the beer still has a cloudy appearance. It's not quite as murky as it was a couple weeks ago but still not a clear beer as you would normally experience in a typical clean fermentation. Even the lambic solera isn't quite this murky although both had the same grain bill and same turbid mash.

Day 23

Here's that mysterious clump floating on the surface of the beer. I still can't figure out what it is. It doesn't look like mold but it seems to be active.

Day 24

If you look at this closer picture, although it's a pretty bad picture, you can kind of tell there's some bubbly foam around the edge of whatever it is. This is the activity that I'm seeing.

Day 25

This is a much better picture. You can see the foam around it more clearly. You can also see off to the right there is another smaller blob. There's actually three blobs.

Day 26

Here you can see all three blobs. They all have that foamy appearance and they are slowly expanding in size.

Day 27

  

Same thing in this picture. I keep snapping pics of the blobs because it's the only visible activity. They are growing. Whatever it is, it's doing something to the beer.

Day 28

 If you compare this picture of the main blob to the beginning of the week or prior weeks you can definitely see it is growing in size.
