Surprising it kept fermenting after 85% attenuation. Yeah, I've heard the thaw is starting to set in, good time for the final bottle. Enjoy.
The go-to yeast chez Brewery Slid is US 05, which quite often goes down to 1.003, especially if you re-use the trub (bizarrely). I really did think that 1.012 would be safe to bottle. But Slids make wort, yeasts make beer. And it seems, yeasts carry on making beer, even when Slid is happy with his finishing gravity.
Final Bottle? I do indeed hope to enjoy this and hope you too get as much from your BW drinking experience as I did. Sort of "one 250ml bottle at 2 months, a 250ml @ 3months, a full bottle @ 5 months", etc. Of the 17 x 500ml or so I finally got, I think as many as 3 may have been drunk over the "festive period".
I feel it is a sort of "have to" experience in brewing, even if 20-40 bottles is as many as you could enjoy (or face) in a whole year.
