The development of false bottoms of lauter tuns has done significant progress from perforated wooden vessels to stainless steel false bottoms with grooves of the throughput up to 18% . The grooves in false bottom are made by milling, welding, laser or water jet . In this article are compared experimental results from lauter process using welded and milled bottoms . Better results in terms of lower impurities content, efficiency of sanitation process, the time of first wort passage and extract content were comparable using welded false bottomThe development of false bottoms of lauter tuns has done significant progress from perforated wooden vessels to stainless steel false bottoms with grooves of the throughput up to 18% .
