Synthetic corks
A synthetic cork is designed to look and function like natural cork stoppers
Synthetic corks from plastic compounds designed to look and "pop" as the natural cork, but without the risk of contamination of TCA. Disadvantages some synthetic wine stoppers are a risk of harmful air in a bottle after only 18 months, and the difficulty of its removal from the bottle and cork with plastic to cover the wine. James Laube of Wine Spectator notes that some of them can give a chemical taste in the light of wine.
Unlike natural corks, synthetic wine corks are made from biodegradable materials not many, but is recycled as # 4 or # 7 (see resin identification code) in many communities. There are two main techniques for the production of synthetic corks: molding injection and extrusion (mono-and co-). Also there are methods which states that combining the two techniques of injection and extrusion. A study in 2007 by Victor Segalen Bordeaux 2 University has shown that the injection molded synthetic closure has allowed the highest levels of oxygen permeability in relation to natural resources of cork and screw caps, with less protection against oxidation of the wine. A new generation of injection molding synthetic corks have developed a nano-system cells to reproduce to perfection the cellular structure of cork and exactly duplicating the natural values permeability of high-quality one-piece natural cork stoppers.,
Screw tapas
Main article: Screw Cap
stopper Stelvin removed
Screw caps or Stelvin caps "are only of materials closures son of aluminum in the bottleneck. They are the main end use by wineries from New Zealand. This can be attributed in part to the initiative of New Zealand CAP thread, which promotes the use of screw caps instead of cork. screw caps form a tighter seal and can prevent oxygen for a long period the cap. These benefits assistance in maintaining the quality of the wine world and the potential for aging. Michel Laroche of Domaine Laroche Note that this played a role in its decision adopting screw caps. "Quality tests show large significant results: in addition to protecting cons cork taint, screw caps are also beneficial in the aging of wine, particularly the preservation of fresh flavor. "
This contradiction is often cited is the case of experiments conducted by the Chateau Haut-Brion, in the 1970s, when 100 bottles were placed in screw cap for long-term observation. The result was, as Haut-Brion, Jean-Bernard Delmas, that "worked perfectly the first ten years, until the plastic plugs are fragile and air. "
One disadvantage of screw lids according to experts Jancis Robinson Wine is the opposite of oxidation, reduction, which can suppress the unpleasant aroma of wine and perhaps a problem particularly affects Sauvignon Blanc is a grape with a natural tendency to reduction. In addition, it is the image of the screw cap, as "Consumers still perceived as screw caps for 'cheap' wines (regardless of price). "
In a survey 2004 views of consumers conducted by Wine Intelligence Consultant found that nearly 52% of U.S. consumers and 60% of British consumers reject the idea of using caps for its wines. In 2007, University Victor Segalen Bordeaux study showed that the caps lock is enabled less oxygen permeability compared to natural corks and synthetic, which offers the highest level of protection against oxidation of the wine.
After studying clinical failures by the International Wine Challenge in September 2006, it was widely reported in the British press that the results show that the 50 bottles with a screw-cap bottles about 200,000 people can be affected by the process of desulfurization of chemicals, causing a failure in which a consumer is "Facing the stench of sulfur – Compared to rubber burned or rotten eggs – instead of a flowers attractive. "Jamie Goode presented arguments against the reports described" science closures represent evil, are full of inaccuracies and misunderstandings, and do not serve the wine industry well, "and went to the uncertainties on specific points.
Vino-Seal
Glass-cap relative corkstopper
Vino-Seal, or Vino-Lok is an attached plastic / glass launched by Alcoa. Since its market introduction in Europe in 2003, more than 300 wineries Vino-Seal used. Using a glass stopper with an inert or in the ring, Vino-Seal creates a tight seal that prevents oxidation and the contamination of TCA. A drawback with the Vino-Seal is the relatively high cost of each card (70 cents each), and the cost of the package manual due to lack of filling compatible computer outside of Europe. The design has won an Award of Excellence for packaging Worldstar World Packaging Organization.
Zork
A bottle of wine sealed with a Zork
Invented by Conor McKenna and developed by John Brooks in Adelaide, South Australia, is a Zork wine closure that seals other like a cork screw and appears as a stopper. The Zork closure is composed of three parts, one outer cover to provide a tamper evident that Clip fits the band CETI cork European standard bottle mouth sheet metal Within that provides a barrier to oxygen like a screw cap and a piston that creates internal op extraction and sealed after use.
Crown caps
Corona close the lid of a sparkling wine.
The bottle cap has been traditional used in sparkling wine industry, the closer in the process of fermentation in the bottle (mthode traditional). Normally, the cap is replaced by cap before shipping, although recently some producers are releasing wines that crown closure at the top. Crown caps lavish a seal, without risk of cork spot. Although easier to open, remove the plates of the ceremony and the mystique of the opening of a sparkling wine.
Opposition
There is a permanent opposition to the use of alternative closures in parts of the developing wine industry. In March 2006, the government Spanish banned the use of replacement plugs in 11 wine regions of Spain as part of his (original title) DO regulations.
Opposition because of the environmental impact of synthetic closures are also increasingly, non-biodegradable synthetic stoppers such as cork, but the main reason is that the cap "farms" have a high biodiversity and some species are unique in the cork-producing regions, however, with reduced commercial demand for cork, most of these farms are removed to more profitable crops.
