There are often emotionally-driven controversial discussions about the ideal closure for wine bottles. The issue is which system is the "right one" for which wine. This is directly related to the second question, if and to what extent oxygen for the development of the wine during the bottle aging or for the durability is required. The air in the whitespace in the bottleneck may be enough, but this is usually in the bottling before closing with inert gas filled or vacuumized. Anyway cork (Natural corks) versus alternative closures such as conventional Plastic corks or screw caps up to a factor of 3 or 4 more permeable.

different closures for wine bottles

Research at the Australian Research Institute AWRI (Australian Wine Research Institute) have shown that a controlled intake in even OTR (Oxygen Transfer Rate) positive flavorings and colour especially of red wines. The required amount, however, depends on the vine, With the red wines Cabernet Sauvignon. Carmenère. Garnacha Tinta and Syrah Under different oxygen conditions, studies have shown that OTR is a key factor in the development of red berry aroma. In the meantime, there are alternative closures, with which an individual oxygen supply is possible (see under micro-oxygenation and oxygen management ).

The demand for alternative closures has increased in the last 20 years due to increasing problems with the corked emerged. This dreaded wine faults can be barely perceptible to disgusting pronounced and makes a wine in the worst case, not drinkable. The discussions about it have become part of a true cultural dispute. The "cork apostles" mean that the use of other closures means a "culture shock" and you do not want to miss the "pop" when opening a wine bottle under any circumstances. Gladly the example is used, it is almost a sacrilege, a Château Mouton-Rothschild of the vintage 1945 as profane Mineral water to open by turning a capsule.

The proponents of the screw caps and the "alternative closure fans", however, believe that one can easily do without this noise, if one for a clear Weingenuss could expect. What is the use of different closures now? Around 60% of the world's wine bottles are still produced by cork closed from cork oak (natural cork). About one third of these are so-called cork granules (agglomerates or corks), which are bound with the help of resin or glue. The tendency for the cork use is due to the Korkschmecker problematic falling.

The most common alternative is the screw cap used, which is ideal for reclosure. This means that around 15% of bottles worldwide are closed with increasing tendency. However, there are a variety of other alternative closures. Well-known products are CorkScrewCape. dolphin. DIAM (flexible oxygen supply), glass corks. HISS. Capsules. Plastic corks. MAESTRO. Nomacorc (flexible oxygen supply), ProCork. STELVIN. Vinolok. VinPerfect (flexible oxygen supply) and Zork, As Dauerverschlüsse are not suitable latches. cork stoppers and bottle stopper,

The tendency of other closure systems is constantly increasing at the expense of natural cork. Especially in New Zealand with 90% and in Australia with 60%, the proportion of alternative closures is extremely high, with a predominant share of screw caps. Even in France, where initially there were major acceptance problems, this is now increasingly prevailing even with high-quality red wines. In the countries of Greece, Austria and Switzerland, more than half of all rising wines are alternatively closed. See topic group also under drum types. bottles. cork and wine vessels,
