This slick unit can be used for bottling both still and sparkling wine. The filler has a tapered fitting that accomodates 5/16", 3/8" and 1/2" siphon hoses. To use, simply attach the siphon hose to the spigot on the bottling bucket and filler unit, turn the spigot on, push the button on the filler and the filling begins! When the bottle is full, the unit automatically stops. Fill level can be adjusted.
