I hope you're kegging. Anything reasonably low gravity ought to work. This time of year, amongst the crowd favorites, I might try the BM Centennial Blond or Orfy's Mild. Both ought to be ready pretty quickly, and fit the spring weather nicely. Naturally, they'll have wide appeal as well.
Both are very fast, very popular with drinkers of all styles, inexpensive, and di I mention fast?
I've been through 11G of each... Brewing another 11G of the Centennial Blonde tomorrow, and then another 11G of the Bee Cave HPA in about a month... with an IPA in between...
