Brew Number 63

• Gumpy's "Boston Cream" Ale kit
• 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
• Wyeast #1728 (Scottish Ale) (1st generation - 26/1/07)

Was brought out to 23L. Used fermenter #1.

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 
   = ((1043 - 1000) * (1 - 69/100)) + 1000
   = 1013.3
