What’s fake cork?

Faux cork is a synthetic material used as an alternative sealant for wine and spirits bottles. It was developed due to environmental pressure on trees that produce natural cork, the susceptibility of natural cork to bacterial rot, and its increasing expense. While faux cork solved some problems, it also attracted criticism for being difficult to extract from the bottle and potentially harming a wine’s flavor and character. Technological developments have led to the creation of synthetic corks that are easier to extract and less prone to oxidation. However, many wine traditionalists still prefer natural cork.

Faux cork is a synthetic material designed to mimic the properties of natural cork, typically used as an alternative sealant for wine and spirits bottles. Since the invention of faux cork, wine lovers have raged in an ongoing battle over whether traditional or synthetic corks are better for wine and safer for the environment. Faux cork is typically made from plastic or a combination of plastic and other synthetic materials.

Several reasons are given by experts for contributing to the widespread development of fake cork in the 1990s. First, rising levels of wine production in the 20th century have led to environmental pressure on trees that produce natural cork. Secondly, natural cork has the disadvantage of being susceptible to bacterial rot, which can spoil the wine by imparting a musty taste. Third, natural cork has become increasingly expensive, in part due to environmental stresses on the crop. These issues combined lead to significant demand for an alternative to synthetic cork.

The original imitation cork products have solved some, but not all, of the problems associated with natural cork. Primarily, their success was due to the fact that they eliminated the possibility of rotting, thus protecting the wine. Additionally, they were significantly less expensive to produce than natural cork stoppers, leading to greater savings for winemakers. Many early alternatives to cork attracted great criticism in the wine world, mostly because they were extremely difficult to get out of the bottle and nearly impossible to reuse to protect an opened bottle. Many were also concerned that using non-biodegradable plastics instead of natural cork created a bigger environmental problem than it solved.

Wine aficionados are often divided over whether fake cork can harm a wine’s flavor and character. Some suggest it may allow for faster oxidation, which inhibits the wine’s aging potential and can lead it to go bad over a short period of time. Others believe that the chemicals used in the corking process have the potential to add a noticeable chemical aftertaste to wine after a short amount of time in the bottle. Typically, winemakers refrain from using fake cork in wine intended to be aged for many years.

In the 21st century, technological developments have led to the creation of synthetic corks that allow for less oxidation and are easier to extract from the bottle. They remain considerably less expensive than natural cork products and many are now made from recyclable synthetic materials. However, fake cork is still shunned by many wine traditionalists, who believe that modern technology can’t replace the original.
