Ultra Stir is a small, easy-to-use stir plate designed to help brewers cultivate healthy yeast in larger amounts affordably. Yeast multiplication requires aeration, which can be achieved by stirring. Ultra Stir allows brewers to create ideal yeast starters and ensure fermentation success with every batch. It features an Australian-approved power cord and a magnetic stir bar, as well as a 3 Watt design that enables brewers to select variable stir speeds of up to 2500 RPM.
