i made a pumking clone that is very high ABV. It's a 15 gallon batch of all grain and after loses, testing, and tasting it was about 12 gallons bottled. We made an error in calculating priming sugar and only added about 8oz of dextrose. It's been carbonating for 4 weeks at 70f. Am I over reacting? I opened one with very very little carbonation. Thanks.
