Mixed fermentation is the process of fermenting wort into beer by manually adding lab grown microorganisms to the wort the morning after it is brewed. This wort destined to be a mixed fermentation beer is cooled in a sterile tank over night and the next morning we introduce a blend of microorganisms into the wort before it is pumped into barrels.
Over the six years we’ve been brewing at the Monolith we’ve shifted the bulk of our production away from mixed fermentation. We still make some mixed fermentation beers, but these are now shifting to be more special projects and lower alcohol products. We are also moving away from purchasing microorganisms from yeast suppliers and instead have been introducing microorganisms cultivated and grown in our lab. We’ve found that the consistency and quality is superior as we’ve been able to optimize growth techniques for our unique processes.
On October 24, 2026 we’re going to be hosting a very special day at our brewery – our second annual Open Brew Day! It’s a free, community focused event that will allow fans of our beer to join us as we brew. Enjoy this rare opportunity to get behind the scenes and watch us brew a batch of our beer that will be fermented in barrels and eventually blended into one of our bottle releases. We’re very excited to have you join us and get behind the scenes as we brew.
At this year’s World Beer Awards, Blind Enthusiasm took home two of the most coveted titles beer: World’s Best Gueuze for Grand Manifesto, and World’s Best Kriek for Fruitful Pursuits: Cherry!
