Contained in a half-glassbottle, the wine is secured by a perfectly reliable stainless steel opening-closing device. It only comes into contact with glass and stainless steel, identical to Mumm's blending tanks in Reims, two materials that ensure ideal preservation. This unit is perfectly suited to the constraints dictated by champagne.
An aircraft-grade aluminum shell protects the glass bottle.
The upper part, known as the "service" part, is composed of a long neck topped by a cork and a ring (which holds the cork and locks the bottle's stainless steel mechanism).
With itsfuturistic appearance, Mumm Cordon Rouge Stellar nevertheless has a shape close to that of a traditional champagne bottle, reproducing as faithfully as possible the earthly ritual of champagne.
