Traditional corks are preferred choice as one of the few natural materials that are capable to hold the wine inside the bottle since 1400. There are blamed for the reason as the wine may become corked if it comes into contact with tainted parts of the cork. The wine may react with the mould from and the infection causes the wine to be corked with the unpleasant smell of a mould. The mouldy smell may be so strong, so the wine is undrinkable even when exposed to air. There is no remedy for this phenomenon you simply can’t remove the corked flavour, so the wine remains smelly and unpleasant to drink. If you're a wine drinker, you've probably noticed that corks are also not easy to remove sometimes because they end up breaking or crumbling in the wine. The main reason why people prefer corks is because they allow oxygen to come into the bottle while other gases are taken out.
On the other hand screwcaps seems like the perfect solution for opening a bottle of wine. Sealing is also easier and they don’t allow the wine to become corked or to oxidate. Now you may be wondering why there are still wine producers who are practising corks before screwcaps.
A screw cap is made of two components: an aluminium cap and a polyethylene liner in the top of the cap top that’s covered with a foil layer. After tons of research, it was concluded that a foil layer controlling the gas exchange, overlain with the right wadding material at the right width which was ideal for a bottle closure; in fact, it was just as good as a cork.
The advantages of the first one is that natural corks are more effective for wines that need to be aged and mature for a longer period of time. So far it seems that the aging process is more effective when preserved using natural corks which have already been exposed to oxygen.
For our commercial purposes, we should not fear the screw cap, since most of them are taint free. Winemakers will use the screw cap enclosure for the everyday drinking wine within their line-up, saving the cash flow for corks in their higher end bottles. There are some elements involved to switch to screw cap, so not only the wine taste is different, but the price of a SAE 37° Flare fittings is less than that of a cork, so you are saving money on a long term. The question continues to haunt the wine industry. Every great winemaker will often offer wines closed with natural cork and this seems to give a big advantage in most of the wine markets. Screwcaps have been associated with inexpensive wines, but this is changing very quickly.
