As I have said before, Dogfish Head is one of my favorite brewers. I cannot say that I love all of their beers. Some, like the Midas Touch, I find to be nearly undrinkable. What I love about Dogfish Head is that when they miss, they miss because they are swinging for the fences. I have never tried one of their beers and thought it was too bland, or just a little bit off, or not quite right. Dogfish Head Beers are either home runs or strikeouts. Their beers are not for the faint hearted. At times, like with the aforementioned Midas Touch, Dogfish Head pushes the boundary of what can be called beer. And when Dogfish beers are good, they are really good.
Case in point is the 90 Minute IPA. The 90 minutes in the moniker refers to the amount of time this beer is continuously hopped. Dogfish Head also makes a 60 Minute IPA and a 120 Minute IPA. There is also a 75 Minute IPA that is a blend of the 60 Minute IPA and 120 Minute IPA, and which is only available on tap. (CORRECTION: I have been advised that the 75 Minute IPA is served on cask and has some maple syrup added.)
The 90 Minute IPA is often referred to as an Imperial IPA, but it is unlike any other Imperial IPA I have come across. It is not nearly as hoppy and is much maltier than the standard Imperial IPAs. There was not much head on the pour, but that slight head lasted to the bottom of the glass. The 9% ABV is very noticeable but is not harsh. If anything, the high alcohol taste balances the maltiness nicely and helps to highlight the spiciness of the hops. The beer is remarkably smooth with low carbonation and a velvety texture. I enjoyed the hell out of this beer, and give it a 9/10.
