Different Types of Wine Bottle Lids
When we think about wine bottles, we picture them with a cork or a screw cap — two of the most common ways wines are sealed.wine lids But there are many other ways to close a bottle of wine, each with its own pros and cons.wine lids The type of closure a wine has can influence the wine's taste and aroma, as well as how it ages in the bottle. Natural corks, which are traditionally used in older world wines, allow a slight exchange of oxygen and can help the wine to age slowly over time. However, they are also susceptible to a fungus called TCA (trichloroanisole), which can cause a musty or moldy flavor and smell in the wine. Cork taint is estimated to occur in about 5 percent of all wines made with cork. Screw caps are a popular alternative, and they have been shown to reduce the risk of TCA in the wine. They are also recyclable and do not come from natural resources. But they can limit the wine's ability to breathe and may cause a slight metallic or rubbery flavor in some wines. Screw cap use is increasing in new world wines, and some winemakers are experimenting with them to see how they affect the wine.
A cork consists of a flexible and porous piece of wood that is cut out of a tree and then placed in the bottle, where it expands to form a seal.wine lids Screw caps are metal lids that screw onto the top of the bottle and have an inside liner to control the rate at which air can enter into the wine.wine lids These types of lids can cause the wine to oxidize more quickly than a traditional cork, and they are not as consistent as a natural cork.
The body of a wine bottle consists of the main part of the bottle and a neck that goes down into the wine to a level above the shoulders, which are the sloping parts on either side of the neck.wine lids The shoulders can vary in height and are a good indicator of how the wine will taste. For example, a wine with high shoulders is usually richer and more concentrated, while a wine with low shoulders is lighter and less fruity.
In the early 2000s, a company in Germany devised a way to secure a wine bottle that kept old romantics happy and eliminated cork taint – it was called Vino Lok and was a circular polymer disc that closed tight over the bottle opening.wine lids But the cost of the closure prohibited it from becoming more widespread. More recently, a wine screw cap called Stelvin has been developed that is similar to the long outside skirt of a traditional cork, but uses a plastic PVDC (polyvinylidene chloride) liner instead of paper. The PVDC can be ordered to allow the wine to integrate oxygen at a slower or faster pace than a traditional cork, and it is a favorite of some producers.
