What are Sulfites?

Sulfites, or sulfur dioxide (SO2), are a group of sulfur compounds that occur naturally in wines and act as a preservative. These compounds have long been used in the wine industry to prevent oxidation, spoilage, and preserve freshness. They function as a safe, anti-microbial and anti-oxidant agent.

    • Prevent Oxidation: Oxidation is a natural process in which oxygen reacts with the various components in wine, causing it to lose its flavor and aroma. Sulfites slow down this process by eliminating any excess oxygen in the wine, ensuring that it maintains its quality.
    • Protect against Microorganisms: Sulfites help inhibit the growth of bacteria, yeast, and other microorganisms that could spoil the wine or cause it to become fizzy or sour.

    Common Misconceptions about Sulfites in Wine

    • All wines have sulfites: All wines contain some naturally occurring sulfites, but not all wines have added sulfites. Some winemakers choose to produce wines without using added sulfites, called "no-sulfite-added" wines. However, these wines are more vulnerable to spoilage and have a shorter shelf life.
    • Sulfites cause headache and allergies: It is a common belief that sulfites are the reason behind headaches and allergic reactions after drinking wine. However, studies showed that only a small percentage of the population is sensitive to sulfites, and it typically affects those with asthma. The primary cause of wine headaches is still debated, but it could be due to various factors such as dehydration, alcohol content, or histamines found in certain wines.

    Regulations and Labeling of Sulfites in Wine

    Different countries have their regulations regarding the use and labeling of sulfites in wine:

    • United States: In the US, wines containing more than 10 parts per million (ppm) of sulfites are required to carry a "Contains Sulfites" label. The maximum limit of total sulfites in wine is set to 350 ppm.
    • European Union: Member countries follow the same general guidelines, but the maximum amount of sulfites allowed in their wines is lower at 160 ppm for red wines and 210 ppm for white and rosé wines.
