Brew Number 55

• Gumpy's "Aussie Pub Draught" kit
• 1.7 kg Grumpy's Medium Bittered LME (25 IBUs)
• Wyeast #2112 (Californian Lager) (1st generation - 20/05/07)

Was brought out to 19L. Yeast pitched at 21.3 degrees. 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 
   = ((1042 - 1000) * (1 - 74/100)) + 1000
   = 1010.9

18/08/2007 15:00	1010	15.4	1009	Bottled

Notes

• Used 180g of priming sugar.
• Got 60 375mL bottles from 23L of beer.
