O'Fallon Brewery Bramble Wildberry is a Kölsch by style. This may be the most refreshing fruited beer that O’Fallon has brewed. We customized a German style Kolsch by adding fresh blueberry and raspberry during fermentation… this adds a soft rounded berry flavor without all the sugar. We brought hops down a bit to let the fruit shine, making way for a low-calorie beer that is light and crisp with a dry, refreshing finish. Bramble could be described as the spritzer of beers! This craft beer is 4% ABV and 7 IBUs. In this craft beer review, we will take a look at the color, smell, and taste.
