More compact than ever. This little Magnetic stirrer is a powerful tool for creating healthy yeast for your brew. Build up the yeast to get the best fermented beer using this Wort Whipper. Use an Erlenmeyer flask, 1000 ml. up to 5000 ml. and you will still get a great result. Keeping the power on low is enough to get the yeast going, no need to create an overwhelming vortex, a small vortex will do the trick.
Do not use boiling wort in a flask directly on the stirrer!
