Something a bit different today when I transferred my brew from the fermenter into the keg. Big gelatinous blobs of what I hope is yeast. Completely different to every other brew I've done in the past, where its been a fairly uniform consistency slightly grainy sediment. I'm wondering if something has gone wrong (or right?). The fermentation went well, and I chilled it to 3.5 degrees before transferring it. Probably the clearest looking brew out of the fermenter I've ever had. This was the first time I used a rubbermaid mash tun rather than BIAB, that is about the only difference I can think of.
Update: final gravity is 1.003 for an alcohol content of 5.1%. That is probably the lowest final gravity I've ever had.
This was the second batch of a recipe based on drsmito's Landlord ale clone (I used WGV instead of goldings and some crystal malt because that is what I happened to have in the cupboard. Aside from that it matches the recipe at http://homebrewandbeer.com/forum/viewto ... 60#p113263). The first batch had a final gravity of 1.010. Between the two batches, I bought a rubbermaid mash tun. I also used O2 to oxygenate the wort, for the first time. (I think I never understood the idea of wort aeration before...). I used a yeast starter based on a recipe I found on these forums (probably also from drsmuto?), splitting it and keeping 1/4 built into another starter for the second batch.
My guess is that that is either break material or clumped yeast. Some strains of yeast will do that; you should see what some of the saison yeasts do... they look much like that but the clumps float on the surface of the beer!
