Please educate me, what is 90 and 120 IPA.
IPA is an acronym for "India Pale Ale". The number refers to the amount of time they add hops to the ferment-er or the keg after fermentation. Dry hops don't add bitterness to the beer but can add a fruity finish to the beer. When DFH does a 90 or 120 minute to an IPA, they drop hop for 90 or 120 minutes. It's my understanding that the 120 minute is very, very difficult to achieve the perfect balance of hops, time and the alcohol is intense. One mistake and their whole years can be up in smoke. That's why it's so expensive.
