Differentiated permeability wine stopper

Guala Closures Group presents a line of secure, performant and sustainable closures under the Wine Developers brand, with the inclusion of special seals by MGJ, able to meet the different needs of oxygen permeability.

Wine Developers closures thus guarantee the proper maturation of each type of wine even after bottling. The quality of the MGJ liners is guaranteed by the use of well known and tested, 100% traceable, EU and FDA approved raw materials. Combined with Guala closures they ensure a regular rate of oxygen transmission that is also constant in time, without requiring modification of the filling line.

Wine Developers has also “signed” a program of replacing tin with aluminum, a material widely available, infinitely recyclable, which entails up to 95% energy saving after first production.
