Light Can Spoil Your Wine!

Wine Spoils When Exposed to Light.

The Science of Lightstrike in Wine: Wine is surprisingly sensitive to light, particularly UV rays. When exposed to light for extended periods, chemical reactions are triggered that can spoil the wine’s flavor and aroma. This phenomenon, known as “lightstrike,” is especially common in white wines and sparkling varieties due to their lighter-colored bottles, which allow more light to penetrate. To protect against this, many wineries use tinted bottles or store their wines in darker settings, reducing exposure to harmful light that could degrade quality.

The Role of Bottle Tints

Tinted bottles, often green or amber, serve more than just aesthetic purposes—they act as shields, filtering out damaging UV rays that could otherwise harm the wine. Red wines are less vulnerable as they contain tannins and phenolic compounds that offer some natural UV protection. However, regardless of the type, proper storage away from light is crucial for any wine to maintain its intended flavor profile.

Why It Matters to Wine Lovers

Understanding lightstrike is essential for anyone who wants to enjoy wine at its best. Proper storage—cool, dark, and stable—is a vital part of wine preservation, ensuring that the taste and aroma remain authentic to the winemaker’s vision. If you’re a wine enthusiast, consider using storage options that limit light exposure to protect your collection.

Fun Facts

  • Sparkling wines are particularly vulnerable to lightstrike and may develop “off” flavors even after brief exposure to light.
  • Many premium wines come in boxes or opaque containers to further shield them from light.
  • Winemakers often test various bottle colors to find the best balance between light protection and brand presentation.
