Speidel's RO-Z style grant/mixing tank is an extremely handy tool in any winery. The open top, 45° mixing port, and total drain outlet make mixing additions into larger tanks a snap - insert your mixer in the 45° port and position the mixing tank under the racking port of your larger tank. Run wine into the mixing tank with the mixer running, pour in your tartaric acid, sugar, bentonite, etc.; and pump out of the drain port to return the wine to the tank.
