Brew Number 62

• Gumpy's "Republican" Dark Ale kit
• 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
• Wyeast #1728 (Scottish Ale) (1st generation - 26/1/08)

Was brought out to 23L. Used fermenter #2.

Apparently the yeast has an apparent attenuation of 71% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1039 - 1000) * (1 - 71/100)) + 1000
   = 1011.3
