As of today, 4. As of tomorrow, 5.
I've done both Pale Ale recipes, the Düsseldorf Altbier, and the Belgian Dubbel. Tomorrow we're brewing the Doppelbock.

Also now the IIPA, ESB, Ordinary Bitter, Scottish 70+/, English Barleywine, Sweet Stout, and Oatmeal Stout. Next up is the Brown Porter.
I've brewed the American Pale Ale a few times, and find that I prefer the recipe on the Jamil Show to the one in the book.
