There are a few of them, if memory serves. One was probably a nice nut brown ale, a sweet and malty, not so bitter or hoppy brew. Another was mentioned as having a smokey taste, probably another brown ale with the addition some smoked malt or grains. Might have been a scottish ale or even an oatmeal stout with the smoked grains added. Mac sounds like an all-grain brewer rather than an extract sort of fellow, but that takes a great deal more time, and I've too ignorant tastes to notice the difference...
