Bottle Filling Stick
A rigid length of plastic pipe that is attached to the end of your syphon tune. At the free end is a very simple valve that is opened when pressed against the bottom of a bottle. Push the filling stick to the bottom of the bottle and the wine / beer bottle will fill flow, take the filler out of the bottle and the flow will stop. Filling has never been so easy.
The entire unit is 33cm long.
