I brewed a really nice Cherry Wheat beer recently. I added 9 lbs of malt extract to the boil and fermented it 1 week before racking onto 10 lb of pasteurized cherries. I added this much malt extract because I erroneously assumed a dilution once racked onto the cherries. Here are the SG readings:
OG = 1.074
SG before racking onto cherries in secondary = 1.015
SG after racking on cherries with gentile mixing to avoid aeration = 1.020 (it went up due to sugar in mashed cherries)
FG = 1.013
Here’s how I calculated it. Since the cherries added 0.005 to the SG, I assumed I could add that to the OG. So 1.074 + 0.005 = 1.079 -1.013 (FG) x 125 + 0.5% for priming sugar fermentation = 8.75%.
Is that at all correct? Can anybody verify this or tell me how to calculate it the right way? Thanks.
