Summit brewing is a few miles out of downtown off 7th street on Montreal Circle, they do tours Tues, Thurs, and Saturdays I believe. It's a great brewery. As far as brewpubs go, I only know of a couple in Uptown in Minneapolis. The Lyndale Taphouse and the Herkimer. Oh, and there's one downtown St Paul called Great Waters but their brews aren't anything great and the fare is mediocre at best. Other breweries around are Flat Earth, Surly, and Lift Bridge(outside of the cities in Stillwater). If you go down by the Grand Avenue area there are a few bars that keep an impressive number and quality of taps going, The Muddy Pig usually has about 80 I think, The Happy Gnome I think is around 45 and The Blue Door has less but the brews are all craft and micro.
