Recipe Generated with BrewMate
Mash temp ended up at about 66.5 C. Problems started with a stuck mash. I have firgured out why this happened - there is a recess in the bottom of the mash tun for the tap and the edge of the domed false bottom was hanging over that, so some grains got in and blocked the tap. I ended up having to take the tap off and shove a skewer in to unclog, resulting in more wort spillage than I'd have liked.
Finished fermenting in about 5 days but stopped at 1012, so I guess I should've mashed at a lower temperature. Can anyone tell me - is this because a higher proportion of my grain bill was roasted/caramelised malts?
Early tastings were disappointing - the Amber seemed to be overpowering everything and making it just taste of mild coffee - not in a bad way but in a one-dimensional way. Now that that is mellowing out it has turned into a really lovely flavourful beer, although I see what people mean about S-04 killing hop flavour!
Anyway - pictures:
Grains weighed and ready - the lucky cat didn't turn out lucky and the grains blocked my mash tun. Shouldn't have let the cat's batteries run out!
