I have been mainly using WLP007 yeast and I can have a beer fermented out in about 5 days to an apparent att. of 78%.
I recently wanted to do the West Coast IPA clone, so I got some Cal Ale WLP001. It took about 12 days to ferment that beer out all the way ( about 80% att. ). I did a 1200ml starter for a 5 gallon batch.
I harvested that yeast cake, washed, then did a 1200ml starter for a 1.047 beer. I am 5 days into fermentation and I am only at 1.026.
Is this normal for Cal Ale yeast? or did I get a bum vial?
I also use O2, and yeast nutrient...my calcium is at about 70ppm.
