So, my family used to spend 2 weeks each summer on Mt. Desert Island in Maine, and one of the highlights of the trip was drinking (and bringing home a case of) Thunder Hole Ale, from the Bar Harbor Brewery. The other night, clearing boxes in the basement, I found an old case with two bottles left. The bottle was about 11 or 12 years old. Curious, I opened it, and it was still AWESOME! The old brewery is gone, but I would LOVE to try to make something close. Does ANYBODY have a partial mash recipe for Thunder Hole?
