Once the wine has finished fermenting you are required to rack the wine (siphon) off the yeast sediment. You may need to do this several times until the wine is sparkling clear and not throwing off any more sediment. This can best be achieved by using a siphon system which is designed to avoid sediment disturbance and to eliminate excessive splashing. If you plan on maturing the wine for a long while we recommend glass carboys. There is also an automatic bottle filler called the Ferrari bottle filler.
