(RK301) This is a simple set up that allows you to transfer your wine from one gallon jug to the next without making too much mess. Simply start your siphon by blowing into the tube just enough to start the siphon flow. Note that the suction tube draws away from the very bottom of the jug and curves toward the side wall so you can see how far above the sediment you are drawing. When the siphon reaches its end, you can tip the jug gently, as in the illustration, to draw all the clear wine you can without disturbing the sediment. Comes with size #6 rubber stopper.
