Organic No Sulphur Wines
Winemakers add sulphur dioxide to wines for its antiseptic and antioxidant properties, preventing the wine from spoiling. However, the sulphur can cause allergic reactions of various types and severity, including headaches, rashes, low blood pressure, and breathing difficulties.
In order to prevent these negative reactions, many wineries have opted to eliminate sulphur dioxide from the production process. No-added sulphur wines are made with no sulphur dioxide at all, so the risk of allergic reaction is reduced. Note: There are very low levels produced naturally during fermentation, so there is no true "sulphur-free" wine. The name "no sulphur" refers to no sulphur "added" during the wine production.
Organic sulphur free wine has a much lower chance of causing negative reactions, so they're the ideal option for those with allergies to sulphur and sulphites. Vintageroots has an excellent selection of no sulphur added (or NSA) wines, giving you options to find wine that you can drink with no fear of repercussions.
