O'Fallon Brewery Knotty is a golden ale by style. Knotty is a light Golden Ale with soft toasted bready notes and a touch of salt. A mix of malts were used to create the backbone for this beer. Red wheat and Special Roast create the soft, toasty flavor along with a subtle tanginess from the acidulated malt. The yeast helps to carry the soft tangy toasted flavor and aroma, giving way to a crisp, satisfying finish. This craft beer is 5.3% ABV and 10 IBUs.
