Sulfite-free wine refers to wine that has no sulfites added during the winemaking process. Sulfites, a type of sulfur dioxide, are a common preservative used in winemaking to prevent the growth of harmful bacteria and preserve the freshness of the wine.
It should be noted that sulphite does occur naturally in the skins of grapes, so 100% sulphite-free wines do not exist!
However, some people may be sensitive or allergic to sulfites, which can cause reactions such as headaches, skin rashes, or difficulty breathing. For this reason, there is a demand for wine without sulfites.
Winemakers who produce wine without sulfites may use alternative methods to prevent spoilage, such as using sterile filtration, natural preservatives, or careful hygiene practices. It's important to note that even wines labeled "no sulfites added" may still contain small amounts of sulfites that occur naturally during fermentation.
Wines without sulfites may have a shorter shelf life than wines containing sulfites and can be stored more carefully to maintain their quality. However, some people prefer the taste and health benefits of sulfite-free wines.
