Just visited a friends house, while there he told me about a beer that his friend tried. His friend tried the beer and said it had a strong mushroom aftertaste, and gave a bottle or two to my friend to try. While I was at his house tonight, we tried the beer. Red Menace from Hales in Seattle. The beer definitely had a strong mushroom flavor to it. I only had a few sips, but possibly qualified as the first beer that I would have actually dumped out.
