O’Fallon Brewery began brewing and selling beer in the spring of 2000, leading with the flagship brand O’Fallon Gold. Since then, the company has grown from a production brewery run entirely by a husband-wife team, to a full-time staff of 14 and numerous part-time employees, all dedicated to making the best beer possible. In June of 2015, O’Fallon opened a brand new 40,000-square-foot facility in St. Louis, complete with a taproom and restaurant. Currently, the brewery offers five year-round brands and several seasonal beers available in limited quantities throughout the year.
