Didnt want to create a new thread so im asking here.
I have brewed double IPA last March (IBU 114) so believe me, it has quite an amount of hops inside.
Yesterday I tasted one of a couple bottles left (it has been maturing for a 10 months or so). And a problem was very much bobbles, the foam was flowing of the bottle, I really fought that it got infected or something. But after tasting... It was totally good, everything was acceptable except CO2... Don`t really understand what happened to my beer. After 2-4 months maturing it was perfect, low on C02, high on hops.
And it happened not for the first time, my milk stout - the same story, after 5-6 months it was foaming from the top tasting good. After a year it was foaming and tasting bad, got sourness...So the question is: Can the CO2 somehow increase? I mean while maturing? And does somebody know what really happened? How are you guys maturing your beer for a 2-3, even 5 years? I really thought that double IPA would last longer.
