One of the best unique beers I've ever had was a Jalapeno ale. The yeast had metabolized all the capsaicin, so there was zero spice. The Jalapeno flavor was crisp and clean, and you could taste a depth of flavor that was normally overshadowed by the heat. It made me appreciate peppers more now that I knew what to taste for. I've been meaning to try and recreate it and then work my way through various peppers/chilies.
