This type of cork is designed for sparkling and carbonated wines, also known as fortified wines. They are considered technical corks, produced from an agglomerated body to which two or three selected natural discs are glued at one end.
They have a larger diameter, which is essential for retaining the high internal pressures of carbonated wine bottles.
