The Demaria/Ferrari wine bottle filler  (often just called a “Ferrari bottle filler”) is a wine-bottle filling tool used in home winemaking or small-batch wine production:

• It’s essentially an automatic wine bottle filler that attaches to a siphon hose from your fermenter or bottling bucket. 

• When you start the flow, the filler will fill a wine bottle and automatically stop when it reaches the right level, reducing spills and waste. 

• The fitting typically works with standard siphon hoses and has an adjustable fill-height and a flow control nut. 

Key Features

• Automatic Stop: The filler stops the flow when the bottle fills up. 

• Easy to Use: Just hook it up to your siphon and bottling setup, push the button, and your bottles fill. 

• Adjustable: Many models let you change the fill level and flow rate.

• DIY/Wine Hobby Tool: Ideal for home winemakers or small-scale bottling operations.
