Stored in the basement, for a few months. Definitely M15 didn't go bad in a few months time. okay, thanks. Glad it wasn't only me! Did you bring the bottle back for a credit? When I opened it up last night, I poured some tasters for my friends. From the nose, they are telling me it smells like garbage. I laughed, and thought they were being funny. I remembered how good it was at the tasting room, the walnut flavor was almost overpowering! Sadly, it wasn't a joke.
