Got an AG batch, OG 1.052, FG 1.01, Blonde ale, s-05, 5 oz cane sugar, 3 weeks at 70, 1 week in fridge. The beer tastes fine but when I first open a bottle, I get a slight gusher. I pour slowly in a clean glass and initially I get some head but within a minute or 2 it pretty much is gone and there is a small amount of bubbles coming up but really the beer is pretty flat. Bottles were clean and used Star San to sanitize. I searched on "gusher, then flat" and read the posts but couldn't find anything exactly like this. It sounds like the CO2 is not fully absorbed into the liquid yet so I think it just needs more chilling time but I sure would like to hear your ideas too. Thanks!
