1) Initial runnings hit 5.75 gallons @ 1.073
2) Second runnings of 7.5 gallons @ 1.033
3) Preboil 13.5 gal @ 1.049
4) 10 gal post boil (lost 1 gallon in boil kettle because of hops clogging mesh screen).
5) 62% efficiency (sigh)
|
|
Fermentation started in 12 hours and going strong at 16 hours. Racked to secondary (Keg) after 14 days. 1.021 (8.0 brix).
|
|
Need to get better mesh screen and planning to get false bottom screen to help keep the whole hops off the screen, though I think it was the pellet hops causing the problems here.
