Brew Number 56
- Gumpy's "Boston Cream" Ale kit
- 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
- Wyeast #1275 (Thames Valley) (1st generation - 19/09/07)
Was brought out to 23L. Yeast pitched at 22.9 degrees. Used fermenter #2.
Apparently the yeast has an apparent attenuation of 77% If that is so the final gravity should be...
FG = (SG - 1000) * (1 - AA/100) + 1000
= ((1043 - 1000) * (1 - 77/100)) + 1000
= 1009.9

Notes
- Boiled with finishing hops for 3 minutes.
- Used 200mL of the 1st generation starter made on 19/09/07.
- Forgot to aerate with the paddle, however it should have been aerated a fair amount as the water addition was vigorous.
- Beer mostly fermented at 18C. Had a few glitches with the software & config so it spent a while at 12C initially.
- Used 160g of priming sugar.
- Got 61 375mL bottles from 23.5 L of beer.
