This episode of SCHULZ INSIGHT will show you the benefits of open fermentation. You will get to know about our ground breaking approach of building the best hardware for it.<\/p>\n

BENEFITS<\/u><\/strong><\/h4>\n

One thing that might have influence on the beer quality are unpleasant hopresins and other by-products being collected during the rocky head state of the main fermentation. These could be easily removed with open fermentation – simply by skimming them of.<\/p>\n

Another benefit is the ability to track the viability of the yeast culture. By observing the appearance of the different head states during fermentation, it is often possible to check the viability of the yeast. This means how happy and healthy those little fellows are.<\/p>\n

For visitors of a brewery, open fermentation gives the opportunity to have an insight into this part of the brewing process, which is often hidden behind stainless steel.<\/p>\n

INNOVATION<\/u><\/strong><\/h4>\n

Our goal has been to design a completely CIP<\/a>-able tank with minimum release of aerosols during cleaning. The design was set to be elegant, simple an functional at the same time.<\/p>\n

To achieve this minimal aerosol load during cleaning, a process avoiding harmful spring or splashing of detergents were invented. By engineering a super even edge for the CIP overflow, cleaning of all product-touched surfaces is possible by laminar flow. Manual scrubbing is no longer necessary.<\/p>\n

Another positive aspect is that the pipes for the process were hidden and just put underneath the insulation, so that the main purpose is not being distracted of this vessel. Furthermore it just looks nice and clean as well.<\/p>\n

Next to the bottom fermenting version, we have solutions for top fermenting beers as well. Therefore, a smart yeast harvest device is implemented into the same design.<\/p>\n
