Had a tour. Definitely cramped with 20 of us, would have been better with 10 people or less. Tour guide was information and passionate, but sometimes made "off colour" remarks that might not be appropriate for every group. I would have preferred to be served the sake while learning - he taught us for about 45, then we had to chug 4 samples in the next 8 minutes to fit his one hour time frame. While the sakes were all super delicious (definitely way better than any sake I'd ever had), I would have preferred to not feel rushed at the end. A great way to spend a nice day in the distillery, before drinking somewhere else.
