Open Fermenting FOR A WORLD OF NEW OPPORTUNITIES
An open fermenter allows the tannins and bitter substances to be skimmed off the top of the kräusen, thus imparting an extraordinary fine and delectable palatability to the beer. In addition, changes in the appearance of the fermentation and the circulation and movement within the tank can be detected in the fermenter immediately In this manner, we developed a fermentation method which protects and fosters the aroma of our beers.
An increasing number of breweries are rediscovering the benefits of open fermentation for themselves, especially the supreme advantages they bring to hoppy beers.
