Germany developed a wine-free pollution cap

Due to the cork problem, wine often deteriorates. Although cork makers claim that the rate of bad plugging is very low, wine experts say that the figure is actually very high, between 1% and 15%, and the wine produces a musty taste due to impurities in the cork stopper itself. If the chances of engine and faucet problems are so great, customers will not turn their backs.

In order to combat the problem of cork contamination, winemakers used spiral caps and artificial stoppers. Some daily meal and lighter age wines accept these substitutes, but these substitutes lack the romance of open bottles, and romance is very important for high-end wines. In addition, these alternatives do not allow the wine to age naturally.

Now WhitehallLine Winery in Napa, California, solved the problem. The winery uses a tin seal cap product called Vino-Seal, which is a sterile cap made of glass. WhitehallLine used this new cap on its own 2003 Napa Collection Cabernet Sauvignon and 2003 Leonardini Chateau Cabernet Sauvignon.

Mike Yulin, general manager of WhitehallLine Winery, said that they hope to find a good alternative, and people hope to seal the high-end wine with more advanced stoppers.

The Vino-Seal features a cork stopper. The 2003 collection of Cabernet Sauvignon will be available this month. This wine looks very much like a traditional cork stoppered wine. Vino-Seal reduces spoilage caused by cork stoppers, eliminates cork debris, and does not require a bottle opener. If you can't drink it once, you can push it back in, and it won't splatter no matter if it shakes or tilts.

Engineers at Alcoa, a German manufacturer of aluminum, developed the Vino-Seal cap, which in Europe is called Vino-Lok. Dean Sevister, winemaker at Whitehall Wine Company, worked with engineers to test the effect of this cap on the aroma, flavor and aging of the wine.

Now that the research work is not over, Mark Lin told reporters that early studies showed that Vino-Seal allowed a small amount of oxygen to pass through as much as natural cork stoppers. Many experts believe that oxygen permeability is the core element of aging.

Mark Lin said, “We studied in Germany for three years. We discovered that by using wine tasting, sealing with Vino-Seal is better than sealing with screw caps and artificial stoppers, which is probably comparable to high-grade cork stoppers, but we also need Observed for several years."

Wine expert Larry Sepstein believes that although the impact of Vino-Seal on aging is not yet certain, its advantages in other aspects are also very attractive. Seperstein said that the Vino-Seal looks clean and beautiful, and the waiter will look at it and treat it as a selling point. Whispering Wine Company's Curtis Wulau likes the stylish design of Vino-Seal and also sees no pollution. Wu Lao said that people drink cork stoppered wine. They do not know that the wine was contaminated by cork stoppers. They thought that the quality of the wine was not good and they would never buy this brand of wine. Sealing with a stopper does not cause such trouble.
