This stopper is made from small 0.2 - 0.4 mm granulate, formed into a cylinder by extrusion under high pressure and heat, then cut and brushed into the final form - the same production process as our AGGLO stopper. Fine granulate gives this stopper improved aesthetic quality and makes it ideal for printing. Both ends are always chamfered to protect against breakage during bottling and it is usually supplied in a longer version, usually 44x23mm, because of the better appearance. Its performance with wine is similar to that of a plastic stopper, but it definitely looks better and has a more 'natural' feel.
Recommended for wine storage up to 2 years, in ideal conditions.
