Brew Number 61

• Gumpy's "Boston Cream" Ale kit
• 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
• Wyeast #2112 (Californian Lager) (2nd generation - 26/10/07)

Was brought out to 23L. Yeast pitched at 29.68 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 
   = ((1052 - 1000) * (1 - 69/100)) + 1000
   = 1016.1
