So I opened a Port Mongo IPA the other day that was bottled in August 2011, just for the hell of it. I figured it would be toward barleywine territory, as aged DIPA's tend to go. It seriously tasted like it was 2 weeks old. The carbonation was still spot on, plenty of citrus/pine hops taste, light bodied. I was seriously shocked. I am typically a proponent of as fresh as possible IPA's/DIPA's, but I could not believe how well this one held up. Anyone else have this experience, with this or any other IPA's or DIPA's?
