The Bubble Indicator is L'Atelier du Vin's intelligent champagne stopper — a hermetic seal for opened bottles of champagne and sparkling wine, with a built-in pressure gauge that shows at a glance how much effervescence remains in the bottle. Open it on Friday evening and know exactly what you'll find when you return to it on Saturday.

A smart and elegantly designed tool for anyone who regularly opens champagne without finishing the bottle. Compatible with standard champagne and sparkling wine bottles.
