The demand for preservative free wine is on the rise. There are several factors that have contributed to this phenomenon. One reason is – some people are well known for having a tolerance level to the sulphites usually found in the wine. It is a well-known fact that it is almost next to impossible to trace a retail wine that is found to be 100% sulphite free. This is partly because a marginal amount of sulphite is utilized during the fermentation process. Fortunately, the said amount of sulphite does not cause any adverse health consequences.
Naturally a question comes to mind – which preservative free wine is harmful to such individuals? The answer is – wines that utilize larger quantities of sulphite during the fermentation process are likely to create many kinds of problems for certain individuals. In the absence of any mandatory legislation about declaration in this regard, not many retailers are believed to list the amount of sulphite present in wine. In some adverse situations, this might even give rise to instances of sickness, vomiting and migraines.
Therefore, the million dollar question is – why are sulphites added to the preservative free wine in the first place? There is some scientific reason behind this. It has been observed when grapes are picked, at times they do get damaged due to automated picking or careless handling. As a consequence, they go about reacting with bacteria present in the air. It is the presence of a sulphite compound in such a situation that helps in arresting this kind of reaction. Major wine brands prefer using the automated picking method as it is considered to be very cost-effective.
It is during the secondary state of wine making process that a sulphite compound is employed. This stage in question is all about the bottling stage where the wine producers feel the need of keeping the said wine from reacting with air found in the atmosphere. This is the sole and exclusive reason the tanks of wine or the bottles are specially sealed with one layer of such sulphur compound. Likewise, there are several companies that are well known for adding a further quantity of sulphite to bottles for preserving the wine on-route to the supermarkets. This is done with a special reason. The fermentation process often involves poor quality grapes as the beginning of the process. It is these low-grade grapes that have a tendency to deteriorate quickly.
The use of preservative in production of wine has been in practice for ages irrespective of whether it a white or red wine. Whenever the fermentation process does not involve the addition of this preservative by human hand, the wine bottle usually contains the words “no added preservative”. Yes, it is true such wines are very trendy and natural. However, the flipside is – they are incapable of holding up to oxidation or bacterial spoilage. The best place to find such wine is the internet. There are reputed online stores like Organic Wine that are presently offering such wine at discounted rates. They maintain a wonderful collection of all major brands and furnish all requisite information via their website.
