GlassRock Champagne corks are engineered for the unique requirements of sparkling wine packaging, where internal bottle pressure of 5\u20137 bar demands a closure with exceptional structural integrity and sealing performance. Our Champagne corks are manufactured to the traditional two-piece construction \u2014 an agglomerate cork body providing the structural core, with two or three natural cork disc inserts at the contact face to deliver the premium sensory experience expected by sparkling wine consumers.<\/p>\n
The distinctive mushroom shape of a Champagne cork after extraction is achieved by the cork’s compression during bottling. Our corks are manufactured to 30.5mm diameter for compression into the standard 17.5mm inner diameter of Champagne bottle finishes. This compression ratio ensures a firm hermetic seal that maintains carbonation and prevents premature oxidation throughout the product’s commercial life.<\/p>\n
All materials comply with applicable EU food contact regulations. Available with gyropalette wire hood system compatibility. Bulk supply available for commercial sparkling wine producers.<\/p>","protected":false},"excerpt":{"rendered":"
