Sulfites and Wine
What Are Sulfites?
Sulfites are a naturally occurring compound that nature uses to prevent microbial growth. They are found on grapes, onions, garlic, and on many other growing plants.
Sulfites: Sulfur-based compounds used to protect wine from oxidation and bacterial activity.
Sulfur Dioxide: Traditionally used to protect wine from oxidation and microbial activity during aging.
Sulfites
Sulfites (also sulphite) are compounds that are often used as preservatives in wines to prevent spoilage and oxidation.

Sulphur dioxide
A chemical compound used in winemaking as a preservative.
Sulfites: An antioxidant and anti-microbial used to preserve wines.
Sulfites: A class of sulfur-containing compounds used in winemaking as an antimicrobial agent, as an antioxidant, and as a preservative.
Sulfites. Naturally occurring substance also added to preserve and stabilize wines. Present in virtually all wines. Often incorrectly blamed for headaches.
Sulfites - Amino acids that result from the breakdown of proteins during fermentation. They may be added to through the addition of sulphur during the winemaking process.
Sulfites - Compounds added to wine to prevent oxidation and microbial spoilage.
Sulphur dioxide - A substance used in winemaking as a preservative.
Sulfites
are a derivative of the element sulfur, widely used in winemaking, though most wineries keep their applications to a minimum. Sulfur may be sprayed in the vineyard to prevent diseases, pests and mildew.
Sulfites / Sulfur
A much maligned element of wine making. While it can be overused and ruin the flavor of the wine if not careful, it is an integral part of most wine making.
SULFITES: Naturally occurring component produced by the yeast during fermentation. Sulfites are found in nearly all wines.
TARTARIC ACID: The principal acid in wine.
Sulfites occur naturally in wine. They are also added to wine. In the United States, wine bottled after mid-1987 must have a label stating that they contain sulfites if they contain more than 10 parts per million.
Sulfites exist in nature and are also added to preserve many common foods, including wine. About 1% of the general population and about 5% of asthma sufferers may react to sulfites. Symptoms often include restricted breathing ability or nausea.
SULFUR/SULFITES
A small amount of sulfur dioxide, a preservative, may be used both in the vineyard and during winemaking to protect grapes and wine from spoilage. Sulfites are a form of sulfur that occur naturally as a by-product of fermentation.

Sulfites, however, should be introduced at once to achieve and unbound sulfur level of 45-55 ppm.

Reducing the sulfites to practically nil can handicap many wines from developing a rich and profound personality. But many producers are improving techniques and their winemaking processes and turning out excellent and flavorful wines.
American wine labels also say wine contains sulfites, and this is true, of course, as sulfites are naturally produced during alcoholic fermentation and sometimes they are added to wine during the making process, ...
Plural: sulfites, as in "this wine contains sulfites." Sulfur dioxide has been used in the wine making process for thousands of years. It has three important functions in wine making.
Sulfites are a form of sulfur that occur naturally as a by-product of fermentation.
sulphur dioxide: Synonyms SO2 and sulfites. An indispensable additive used in winemaking (although yeast naturally produce small quantities during fermentation).
Sulfur
An anti-oxidant used in wine making process. Fermentation naturally creates small amounts of sulfites. It is required by law to indicate presence of sulfites in the bottle. Some people are sensitive to sulfites and should avoid wine.
Sometimes powdered sulfites are sprinkled on the grapes prior to crushing to prevent too much reaction with the air. The fermentation usually takes place in open vats.
The level of added sulfites varies, and some wines have been marketed with low sulfite content.[61] Sulphites in wine are not a problem for most people, although some, particularly those with asthma, can have adverse reactions.
Some asthmatics also react badly to high doses of sulphur, which has lead to some countries' requiring the legend 'contains sulfites/sulphites' on wine labels.
Organic wines are made from organically grown grapes, that are fermented naturally with minimal addition of sulfites.
Overcropping
The process of overcropping is growing an excessive number of grapes on a vine, sacrificing quality for quantity.
