Pg.169 if you're playing along at home... Well, something went awry somewhere - I know what I measured but I cannot get brewers friend to tally with my BG, OG and volumes at start and end of the boil. I reckon I measured a volume wrong somewhere along the way... And I got nowhere near as much boil off as I normally get - I'm putting that down to the cold weather..... Nevertheless, everything seems basically ok - my OG is a little off from the book, 1.047 instead of 1.049 but close enough for me. I've been discussing problems with loads of trub recently so I tried out some very fine nylon bags - a big one for the grain, and a little one for the hops. The wort for my OG sample seemed especially clear so let's see what happens. I've been playing around recently with growing yeast so for the first time I pitched a starter of Wyeast 1056 American Ale that I'd cultured up myself from next to nothing - fingers crossed!
