A small Czech company, established in 2017, manufactures and trades innovative equipment for preservation of sparkling wines and champagne in open bottle. It is easy to use and brings economic benefits both to customer and provider (seller) of sparkling wine. The system consists of special stopper with valve which closes opened bottle with the rest of sparkling wine and a feeding device which fills the bottle by CO2 to preserve quality of sparkling wine.

The company can offer further equipment like sodamaker, glass cooler and the other. The company is active mainly on the Czech market, but has already some experience abroad. It would like to broaden its activities mainly to Germany, France, the Netherlands, Austria and the USA. The company is offering cooperation on the basis of commercial agreement. The products can be useful for partners that have connection to sparkling wine manufacturers and distributors, restaurants, bars, wine shops as well as for distributors/sellers of food/ beverage industry equipment, etc.
