venturi tube

During the brewing process, wort aeration is the only opportunity to provide oxygen to the yeast. A venturi tube is a common device used in breweries. It uses the negative pressure generated when the wort flows through the throat at high speed to inhale air. The air and wort mix in this turbulent flow, dissolving oxygen. In addition to the venturi tube, a wort aeration system also includes air filters and sterile air filters.
