Wine Word of the Week: Closures

By Kori ~ February 28th, 2012.

This week’s Wine Word of the Week is closures.

Official definition from Jancis Robinson’s The Oxford Companion to Wine:
Closures for wine containers are necessary to avoid harmful contact with oxygen and have changed remarkably little until recent times. Corks are still the principal closures used for wine bottles, just as they were more than two centuries ago and probably long before that, although alternative stoppers are increasingly common, thanks primarily to the rise in the incidence of corked wine as a result of cork taint since the mid 1980s.

Layman’s terms from Kori:
Closures are whatever mechanism is used to close a bottle of wine. Corks continue to be the most commonly used closures; however, in recent years, more and more wineries are experimenting with alternative closures such as screwcaps and glass stoppers in an attempt to eliminate cork taint.
