Sulfite is used to impede oxidation, preventing the wine from spoiling. Have you ever wondered why aged red wine is expensive? Well, time alters the overall flavor of the fruit in the wine and lowers tannin and acidity — the reason why you enjoy a pleasing flavor in the wine.
A younger wine means no SO2 and, therefore, has a shorter shelf life of about six months. At least in the U. This is mandatory according to their legislation. Naturally, a glass of wine with an occurring level of SO2, without additives would weigh around 10 to 20 ppm. With most averaging wines at ppm, the legal maximum sulfite level allowed for the U. Though the consumption of sulfites is almost harmless, it may trigger those who are asthmatic or are prone to severe asthma.
They may not have the particular enzymes necessary to break down sulfites in their bodies. Some sulfite side effects to watch out for are regular headaches, broncho-constriction, dizziness or nausea, skin flush, and nasal congestion. Nevertheless, FDA estimates that less than 1percent of the U. Interestingly, even an organic sulfite-free wine, may contain 10 to 40 ppm sulfites. This is because of the fermentation process as a by-product of yeast metabolism that happens naturally to produce Sulfite.
However, wine made from organic grapes means that the grapes are certified, but the other additional ingredients are not. They may contain up to ppm sulfites. Apparently, white wine has more sulfite content than red wine. Red wine gets ample tannins from the skin of red grapes, which act as a stabilizer.
When this is combined with malolactic fermentation and antioxidants helps for wine preservation; hence it requires less sulfur dioxide. A substantial fraction of people have a misconception that red wine causes headaches. Research done, has shown a likely result of eating packed food with Sulfites like Wine and cheese.
Since they release histamines that can aggravate this, although dehydration caused for not drinking water alongside wine contributes to headache. Wine has a minuscule amount of 20 to PPM parts per million of sulfites.
McKenzie Hagan April 14, With the rising popularity of sulfite-free wine, many wine lovers are left wondering if they should cool it on their favorite Chardonnay and reach for an organic bottle of wine instead. But are sulfites really hurting us? Luckily, the harmful effects of sulfites in wine have been greatly exaggerated. You may have only noticed them sneaking about in the fine print on your wine label, but sulfites are common additives.
Scientifically speaking, sulfites or sulfur dioxide, as they are also known are chemical compounds that contain the sulfite ion. While sulfites occur naturally in some foods and are even found in the human body , they are also commonly added to food and drinks, due to their preservative, antioxidant nature.
There are two types of sulfites you should be familiar with: natural sulfites and added sulfites. Both of which are commonly found in wine and both of which are nothing to worry about. When it comes to wine, naturally occurring sulfites cannot be avoided — they are naturally occurring compounds that are produced during the fermentation process. These compounds are added to many perishable foods, including:. The role of sulfites in wine is to preserve the color, flavor, and aroma that the winemaker intended, as well as lengthening its shelf life.
Without these protective preservatives, wine is vulnerable to oxidation which causes the wine to go bad, taking on a putrid, vinegar flavor , as well as yeast and bacteria.
Taking advantage of the preservative power of sulfites stops your favorite bottle of Syrah from becoming a very expensive vinegar. Adding sulfites to certain meats is also forbidden, as sulfites can disrupt the nutritional value of the product. And although it took seven long books to understand Snape, give me five minutes and I can explain everything you, a person who drinks a lot of wine, actually needs to know about sulfites. There are two types of sulfites, also known as sulfur dioxide: natural and added.
Natural sulfites are just that, totally natural compounds produced during fermentation. And you cannot escape them. Sulfite-free wines do not exist. It is literally literally impossible. No way. Added sulfites preserve freshness and protect wine from oxidation, and unwanted bacteria and yeasts. Without added sulfites, a Bordeaux would be considered trash vinegar rather than a treasure.
