What is corker?

Corker is a term used to describe a type of wine bottle stopper. It is made from the bark of the cork oak tree, which is primarily found in Portugal. Corks are known for their ability to create a tight seal in wine bottles, which helps to preserve the quality and taste of the wine. Corks are also biodegradable and recyclable, making them an eco-friendly option. However, in recent years, some winemakers have started to use alternative closures, such as screw caps and synthetic corks, due to concerns about cork taint, which can affect the taste of wine.
