Corks made from the bark of cork oak trees have been the dominant type of closure used in wine bottles for thousands of years. They allow for a slow and controlled exchange of oxygen, contributing to flavor development.
Understanding Corks
Advantages of Cork
Corks allow minute amounts of oxygen, crucial for aging, and are sustainable as cork oak trees can provide a renewable source of closure.
Disadvantages of Cork
Corks can suffer from cork taint due to TCA, affecting up to 5% of corked bottles.
