Well, if you're going to have beer for breakfast, why not a nice Oatmeal Stout?
And I agree about the Mic Ultra - BLECHHH!!!!
Little known fact, if you want a lower calorie beer, drink Guiness Draught!
It's an incredibly light beer, which is why it floats on top in a black and tan. It really doesn't deserve the motor oil reputation that it has (now that Oatmeal stout I mentioned, that's 10w40!).
Of course, if you can get it, some of the best mimosas are made with Maui Brut sparkling pineapple wine. I still have a few bottles at the house.
