Brewdate: 12 February 2018. Captain Slog:
This brew close to Graham Wheeler recipe for relatively low-alcohol best bitter from Black Sheep. Followed recipe quite closely, upping Challenger hop dose from 21g to 25g to compensate for relatively low AA content. Otherwise identical.
Noticed during mash that Braumeister 'fly sparge' was uneven, showing preferred channels through the grain pipe. Not seen this before and wondered if the thinner mash was responsible (at 5.85L/kg, it was significantly thinner than we usually do, with a target of ABV 3.8%).
Measured OG after mash at 1.040, indicating 65% efficiency despite uneven flow through malt pipe. Volume into fermenter was 20L and OG 1.042, projected ABV 4.0%.
Fermentation set-point 19C, actual T will be close to 19.5C.
FG 1.006 - adjusted attenuation to 83%.
