Session Notes
Yeast Strain(s) Used: WLP001 California Ale
Fermentaion Temp: 67F
Start with 8 gallons of wort from the mash and into the boil planning to boil off 2 gallons, leaving you with 6 gallons to ferment. You will lose the other gallon in dry-hop and transfer to the keg. Also, the first 3 zero hop additions Columbus, Centennial and Simcoe (these Simcoe were actually Citra) are dry-hopped during the first week of secondary fermentation. The other 2 zero hop additions of Columbus and Simcoe (these Simoe were also actually Citra) are dry-hops added during the second week of secondary fermentation. Total dry hop time is 2 weeks.
