I cracked open my #infinitybeer and OMG volcanic CO2, again. Drat!
I think I'll have to break a rule and burp the bottle as it ferments, because the pour was literally all head.
Not a bad flavor though. Light, but with a backdoor bite. This is the first pour that actually tasted like a traditional beer.
@upside if you're still in primary or even secondary fermentation, you need an airlock! there will always been increasing pressure and you need to vent it safely and without introducing oxygen.
