The blades fold down allowing for easy insertion into a barrel or even a

glass carboy. Ideal for mixing, stirring wine and works great as a

degasser. 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.
