Schniklefritz (Urban Chestnut Brewing), Weinhenstephaner, Paulaner, and Franziskaner.
Urban Cheatnut also makes a great Bavarian Lager called "Zwikel." Nice to have a craft brewer make solid German beer styles as year-around offerings. I can't get UCBC beer in KC so I always make sure to stop by the beer store any time I'm in STL.
