Brew Number 57

• Gumpy's "Belfast Gold" Stout kit
• 1.7 kg Grumpy's Dark LME (34 IBUs, I think - this one had some hop oil with it)
• Wyeast #1275 (Thames Valley) (1st generation - 19/09/07)

Was brought out to 19L. Yeast pitched at 24.62 degrees. Used fermenter #2.

Apparently the yeast has an apparent attenuation of 77% If that is so the final gravity should be...

FG = (SG - 1000) * (1 - AA/100) + 1000 
   = ((1051 - 1000) * (1 - 77/100)) + 1000
   = 1011.7

Notes

• Boiled with finishing hops for approx 3 minutes.
• Used 200mL of the 1st generation starter made on 19/09/07, made some more with the last 100mL.
• Beer fermented at 18C.
• Got 51 375mL bottles from 19L.
• Used 160g of priming sugar.
• Appears it wasn't stuck but must have slowed down a lot.
