Brewing a Decoction Mashed & Open Fermented Hefeweizen | Grain to Glass | Classic Styles

Date: 2020-02-09

In this video, I brew a traditional decoction mashed and open fermented hefeweizen, which is a tough project! This video covers the recipe, the brew, the fermentation and the final tasting. This took two tries to get right and added 3 hours of work to my brew day, but was really quite fun. The resulting beer had some really interesting characteristics but probably is not as good as it could have been. However it was a fascinating experiment and a good test of my brewing capabilities.
