Sustainable and taint-free corks are the latest innovations to hit the ‘spirit stoppers’ market. Distillery by-products such as grape marc from cognac, barley malt from whisky and juniper from gin make up 50% of the raw materials used to produce ‘Abor’ corks. Manufacturers, the Tapi Group, are “seeking to create brand awareness in an eco-sustainable way” with their ‘green’ and sustainable new closures. Cork Supply, by contrast, have just released a range of ‘taint-free’ corks with a money-back guarantee. Their vision was to “produce quality closures that add value to the industry”; taint-free cork stoppers will surely have a place in the world of cognac. Unlike wine, cognac should always be stored in an upright position to minimise any effect the cork might have on the spirit liquid and vapours – a problem that can occur, especially in older vintages.
