The shipment included both the Summer Session Ale and their IPA.
My take on them?
The IPA comes it as 76 IBUs and initially hits you with a pine like taste, not that I've even eaten any part of pine tree, so my initial reaction wasn't a pleasant one. Surprisingly, the pine taste quickly passes, leaving one with a nice IPA.
The Summer Session Ale left me a little wanting, probably because it tasted more like an IPA (61 IBU's) and less like the usual summer ales one finds (Sam Adam's makes a fine summer ale IMHO.) So, maybe it was expectations that failed me and not so much the beer. That being said, there wasn't a stark difference between Peak Organic IPA and Summer Ale.
I'd put the IPA at 3.5 Steins and the Summer Session Ale at 2.5 Steins on a scale of 1 to 5.
Ah well, I still have some Mad River Brewing Company to partake in.
