Easily degas wine kits, stir your lees back into suspension, or mix in additives when making wine. This handy tool, also some times called a degasser, attaches to a drill for fast, easy stirring of wine. The blades fold down allowing for easy insertion into a barrel or even a glass carboy. As soon as you turn your drill on the blades expand to create a powerful stirring action. We do not recommend using in a carboy that is topped full because the stirrer displaces too much liquid and also creates a vortex that will send wine out the top. In these cases a hollow racking cane works exceptionally well. Works with 3/8" or larger drills.,,Stirrer is around 22" long.
