Brew Number 42

• Grumpy's "Colonial" Mild Irish Stout
• Grumpy's Dark Malt Extract
• Wyeast #1335 (British Ale II) (1st generation - 27/05/06)

Was brought out to 20L. Yeast pitched at 24.1 degrees. Used fermenter #1.

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 
   = ((1051 - 1000) * (1 - 74/100)) + 1000
   = 1013.7

• Got 53 375mL stubbies from 20L.
