Know the Pros and Cons of Wine Closures

All-natural Corks

Natural corks are one of the most common method to seal bottles, accounting for 60 percent of wine bottle closures each year. Derived from the Quercus suber, or Cork Oak tree, the material is impenetrable, and expands once inside the wine bottle, despite the shape of the neck of the bottle, to develop an airtight seal. The cork also expands and contracts with changes in any environmental fluctuations.

On top of that, several wine fanatics correlate organic corks with elegance and high-end wines.

A common problem of standard wine corks is the fracturing that takes place naturally in the bark. This can result in oxidation due to excessive oxygen exposure. Natural corks can also become brittle when as well completely dry, resulting in the cork breaking while opening, or creating pieces of cork to break short as well as drift in the wine.

Another leading problem is cork taint, triggered by the presence of trichloroanisole (TCA). TCA is most commonly produced from naturally occurring fungi in the cork. Cork taint can trigger wine to have a moldy smell and “corky” taste. According to Vintage Cellars, cork taint impacts 3 to 15 percent of wine bottles, and could occur regardless of the type or price point of the wine.

 

Synthetic Corks

To protect against cork taint and achieve higher top quality control, numerous wine makers have started using synthetic (or plastic) corks in lieu of all-natural corks. Synthetic corks function just like an all-natural cork, but are immune to the fungal contamination found frequently in natural corks.

Synthetic corks also have their downfalls. Unlike natural corks, synthetic corks do not adapt to their environment, which can result in an imperfect fit for the bottle. A cork that is too loose can allow too much air and damage the wine; a cork that is too tight can block out the small amount of air had to assist wine age and develop as intended. Additionally, when a synthetic cork is too tight, it could be tough to get rid of from the bottle after about 18 months.

 

Screw Caps

Twist-off caps are coming to be increasingly popular among wine makers searching for options to all-natural corks for both mainstream and also high-end wines. Like synthetic corks, screw caps maintain a tight seal and do not weaken, therefore stopping oxidation caused by excessive air entering the wine bottle. This can aid in the long-term aging of wine. Screw caps are also immune to cork taint.

Wine enthusiasts argue that the airtight seal set up with screw tops can hinder wine gradually, capturing in unpleasant flavors and also shutting out the restricted amount of air needed for flavors to develop. But, perhaps the biggest concern with the use of screw caps is the assumption that twist-off tops are simply for “cheap” wine.

 

Smart Wine Storage space

Whether a wine is sealed with an all-natural cork, synthetic cork or screw cap, it is still important to maintain consistent conditions to promote the best possible development of flavors. By being cognizant of the advantages and disadvantages associated with each kind of closure, you can make an informed decision on for how long to save wine just before appreciating. When in question, speak to the wine mold to determine the appropriate storage space time for your special container of wine.
