I happened upon a great deal for Paulaner Oktoberfest Bier, Paulaner Oktoberfest Märzen, and Warsteiner Oktoberfest. I had always thought Paulaner OM was a favorite, but Warsteiner was the best of the three with OM falling in the middle. Normally I drink my way through a range of O'fests, but never side by side. Since I had 12 packs of all three I did a SxS as well as one after another in various orders. Warsteiner was the best of the bunch each time.
