The CHAMPAGNE FRESH uses counter-pressure by means of hand pump to prevent the escape of carbon dioxide from the bottle. Install the pump pin in the hole of the closure (built-in check valve), pump two or three times and then remove it again. By using this method the opened bottle of sparkling wine remains fresh for up to two weeks.
The carbon dioxide of the sparkling wine escapes into the empty space of the bottle.
Scope of delivery of the Champagne Fresh:
1 hand pressure pump
