As we tried to answer some of these questions we ordered a Pilsner, Marzen, and Helles Lager.
The Pilsner was straw colored with a scant floral aroma and was cleanly bitter, as good German pilsners are. As we drank we discussed how different beers, all brewed with hops as a main ingredient, can taste so different. The bitterness of a German Pilsner is vastly different from the bitterness of an IPA, owing to varying hop varieties, differing recipes and ratios, and a host of other factors.
The Marzen was a translucent copper brown and less bitter than the Pilsner, and inspired us to re-brew our FBB Marzen, the second ever beer we made. The lager was golden in color, very light and smooth. We also tried a seasonal, their Dunkelweis, a dark wheat beer. It had a banana nose and taste, with chocolate tones mixed in.
We never were able to learn much about their brewery or history, despite asking everyone we could find. We learned from their web-site that they began in 1989 and have only an ancillary connection to the brewery school at Davis. We don't know how many barrels they produce per year.
Generally speaking, we enjoyed their beer and liked their facility but were unimpressed with the experience. And their food was pretty bad, but this blog isn't about food.
Give their beers a shot, but don't worry about visiting Davis, CA to do so.
