Ferrari Automatic Bottle Filler. This unit can be used for bottling both still and sparkling wine. The filler has a tapered fitting that accomodates 5/16", 3/8" or 1/2" siphon hoses. To use, simply attach hose to the spigot on your bottling bucket and on the filler unit. Turn on the spigot on your bucket and push the button on the filler and the filling begins. When the bottle is full, the unit automatically shuts off. The rubber boot that fits into the bottle neck can be moved to adjust the fill level. The nut on the top of the unit allows regulation of the flow.
