Sulfites 101 – Everything You Need to Know

What Are Sulfites?

Sulfites are naturally occurring and added chemical compounds that act as preservatives in many foods and beverages, including wine. They help prevent oxidation, spoilage, and bacterial growth, ensuring longer shelf life and stability.

Why Are Sulfites Used in Wine?

Winemakers have used sulfites for centuries to preserve wine’s freshness and prevent unwanted fermentation. While all wines contain some naturally occurring sulfites, additional sulfites are often added to stabilize the wine during production, transportation, and storage.

Do Sulfites Affect the Taste of Wine?

Although sulfites don’t directly alter wine’s flavor, excessive amounts can mute its natural aromas and characteristics. Many wine lovers seek to reduce sulfites to experience a more vibrant and authentic taste.

Can Sulfites Cause Side Effects?

Some people are sensitive to sulfites, experiencing symptoms like headaches, nasal congestion, or skin irritation. While sulfite sensitivity is rare, reducing sulfite intake can improve the wine experience for those affected.
