My pumpkin ale actually turned out very good with great flavors. It fermented quickly as the temps were in the 70’s. But, all went well and I bottled after two weeks. After week three I tried the brew and it was good. After week three I re-tried the brew and it was greater with good head and carbonation. After week four I refrigerated a batch of about 12 bottles and the beer hazed which was fine. The problem was the carbonation disappeared…virtually flat when chilled. I am going to warm some up to see the results. The temp was probably in the low 40’s. Too cold? thanx
The CO2 will stay dissolved in the cold beer better so it could just look like it’s less carbonated, but if it’s completely flat I think it is more likely that the cold bottles you tested just had a bad seal and were never carbonated in the first place. I would check some others.
I suspect ill-fitting caps or a priming issue. Did you use Muntons carbonation drops?
