"CHAMPAGNE" stoppers


Basically the agglomerated stopper produced in a larger size, it can be plain agglomerated, or capped on one end with one, or two discs from natural material. In this case, quality grades are Extra, 1st class, 2nd class or 3rd class, depending on the disc quality. It always has the agglo end (or both ends in case of plain agglo stoppers) chamfered, and is always produced in non-washed form.

Dimensions are usually 48 or 47mm length, and 27, 29 or 30.5mm diameter.
