Here is another additional to a month of waffle recipes! I generally use whatever local beer I happen to have on hand, most recently a stout from Five and Twenty Brewing. The original recipe called for a german lager. The overall beer flavor of the waffles is pretty subtle.
For cherries, I use local sour cherries, which I can purchase frozen and pitted from Arrowhead Wine Cellars. Do note that once defrosted, the cherries deflate a bit, so I usually use 3 cups frozen for the 2 cups in the recipe. In the summer, when blueberries are plentiful, they are a good substitute.
