I started this brew quite early this morning, and had the mash on at 06:55.
I didn't quite have enough Pale Crystal, so made up the slight difference with a dash of Caramalt but apart from that, the brew has gone to plan. I didn't quite collect the 20L that I was aiming for, but wasn't far short and I think that this was down to not having a good enough siphon effect from my pick up tube as the last few hundred ml of wort was sat at the bottom of my boiler.
I pitched the reydrated Gervin yeast after lunch, and it's now sat in my Brewfridge at 18-19C.
Hope everyone else's brews are going ok.
Cheers
