Brew Number 68

• Gumpy's "Boston Cream" Ale kit
• 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
• Wyeast #1335 (British Ale II) (2nd generation - 30/3/08)

Was brought out to 23L. Used fermenter #2.

Apparently the yeast has an apparent attenuation of 74% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1047 - 1000) * (1 - 74/100)) + 1000
   = 1012.2

27/07/2008 16:00	1012	13.75	1011	4.6%	Bottled

• Temperature set at 20C (new AVR only controller!), dropped to 14C after ferment done.
• Made new starter.
• Used 160g of priming sugar.
• Got 60 375mL bottles from 23L of beer.
