Corking techniques refer to methods used to seal bottles, particularly in the wine industry. The most common method involves using natural or synthetic corks that fit snugly into the neck of the bottle, preventing air from entering and preserving the wine's quality. Proper corking is essential for aging wine, as it allows for a small amount of oxygen to interact with the wine over time. Another technique is the use of screw caps, which provide an airtight seal and are increasingly popular for both wines and other beverages. Corking can also involve the use of capsules or wax seals for added protection and aesthetic appeal. Each method has its advantages, depending on the type of beverage and desired aging process.
