Professor, you have been brewing almost longer than i have been alive, so i yield to your knowledge. do you care to share your secret to having a quality ipa that can run out longer than six months?
genuine interest here.
It all comes down to your personal tastes and preferences. I've had a lot of IPAs that were older than 6 months and still tasted great. But my own preference is for IPA "styles" that are ready to drink when they're younger.
This is a crazy question... The IPA was created to keep beer "fresh" on the long trip from the UK to India for the troops there. So the whole reason for the style was for it to
survive long periods of time. However, the style in America has become a completely different animal. We are obsessed with the hop aroma and flavor (And I am firmly intrenched
in the 'WE' in this sentence) which dissipates with time. So is the beer OK... without a doubt it is! Is it as flavorful and aromatic as the brewer intended... probably not.
I say ask for a taste. You are the one serving it. If it tastes OK to you, then by all means let it fly. If you are not satisfied with the taste, then pass.
