Brew Number 39

• Grumpy's "Boston Cream" American Ale
• Grumpy's Low Bittered Light Malt Extract (20 IBUs)
• Wyeast #1335 (British Ale II) (2nd generation - 14/12/05)

Was brought out to 23L. Yeast pitched at 25.5 degrees. 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 
   = ((1043 - 1000) * (1 - 74/100)) + 1000
   = 1011.2
