Tapered Natural Corks for Cask Keystones
Our tapered corks for cask keystones are designed to provide a secure fit when sealing casks. The tapered design allows the cork to fit firmly into the cask keystone, making them ideal for breweries and cellar managers looking for a reliable traditional cork closure.
Made from natural cork, our tapered corks are a traditional choice for the cask ale brewing industry. We use natural cork only and do not use agglomerated, reconstituted or granulated cork for our brewing corks.
NATURAL CORK – NOT AGGLOMERATED
We supply natural cork brewing closures, rather than cork products manufactured from bonded cork granules or particles. Natural cork is harvested from the bark of the cork oak tree without cutting down the tree, making it a renewable natural material.
