ABSTRACT:
A champagne pressure gauge provides a small tube attached to the inside surface of a bidule inserted into a champagne bottle, such that as the pressure from fermentation increases, liquid is forced up the tube. The liquid level in the tube can be observed through the neck of the bottle, giving a non-intrusive, non-destructive measurement of pressure in the bottle.
