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