Beer Cork 44 × 25.5 mm

The Beer Cork is a high-quality closure made of natural cork, specifically designed to fit Belgian-style beer bottles and to preserve beer flavor and carbonation. This 'micro-agglomerated' cork is composed of small, uniformly-sized cork granules. Before the granules are molded into their final shape, they are cleaned with supercritical CO₂ to remove harmful chemicals that can affect flavor. Because the corks are designed for a tight fit, a Champagne corker is required to insert the beer corks. After insertion, the straight cork will take on the classic 'mushroom' appearance. A cap and wire hood is required to ensure that pressure from the carbonated beer does not force the cork out of the bottle.
