Brew Number 54

• Gumpy's "Boston Cream" Ale kit
• 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
• Wyeast #1335 (British Ale II) (3rd generation - 17/05/07)

Was brought out to 19L. Yeast pitched at 31.1 degrees. Used fermenter #3.

Apparently the yeast has an apparent attenuation of 69% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1041 - 1000) * (1 - 74/100)) + 1000
   = 1010.7
