When I heated my home with oil, I used an average of 800 gallons a year. I have found that I can keep comfortably warm for an entire winter with slightly over half that quantity of beer.
When drinking a quality brew, it's great to be able to say, "hey that's pretty good, though I think I could make something just a little bit better."
Though I tend to brew darker ales, I do like to learn about and appreciate all different styles of beer. I started brewing to celebrate what I like best about beer and to create some styles that showcase how good types of beers can be made even better.
