Sip on this...

I currently have in my fridge 3/4 pack of Dogfish Head 90 Minute IPA.  IPA's are by far my favorite style of beer.  That being said, the 60 & 90 Minute are by far the cream of the crop for me.  I have yet to try the 120 Minute IPA, nor have I had the 75 Minute, but feel free to get in contact with me if you have some extra ;-)
