Saint Arnold of Austria (580-640 CE) is credited with the great miracle of quenching the thirst of his many caretakers with only one cup of beer that never ran dry. Saint Arnold Brewing Company, started in 1994 by two Rice University graduates, is the city's first microbrewery and is named after this saint. No brewing additives or preservatives are used, and to keep it pure, there is no pasteurization. Examples of the company's bestsellers include Kristall Weizen, Brown and Amber Ale. The brewery is not open for general drinking, but you can take tours on Saturday from 11a to 2p with tours leaving on the hour and 3p on weekdays. A beer tasting comes with every tour and unlike Saint Arnold, you won't have to share.
Buffalo Bayou Brewing is by far one of the most adventurous breweries in Houston. Brewing up beers like Gingerbread Stout, their tribute to BBQ beer Smoke on the Bayou and many more, all the beverages include some sort of tribute to various Houston points of pride, be it anything from the date the city was founded to the city's prestigious Rice University. Visitors are encouraged to bring their own food and hang out during the open house and soak up the Bayou as much as possible!
Karbach Brewing has been brewing and serving Houston since 2011.

Favorites from Karbach around the city include the Hopadillo IPA, Weekend Warrior Pale Ale and Karbachtoberfest to name just a few. Friday evenings and Saturday afternoons come in to the brewery for a tour. Admission price gets you a souvenir glass and four drink tickets. In addition to the brews, open house days also see food trucks come in to the drinking area so you can soak up a little of that beer.
