Winemaking is the intersection of biochemistry, microbiology, botany and art. Historically consumers were happy with wines that would be aged over far longer periods, today most wine is consumed within months of production resulting in softer, gentler wines that are commensurately susceptible to oxidation, ageing and shelf instability.
Sulfur dioxide, or SO2, remains the most important additive used in winemaking. There are very few wines that are made without some use of SO2. This is because wine is perishable, prone to oxidation and the development of aldehyde off-odors. Whilst SO2 has major processing and shelf life benefit for the winemaker, there are key considerations as to why producers and customers are keen to reduce the use of SO2 in wines, including Health, Taste and Natural challenges.
Today oenological tannins are widely used in the wine industry to improve wine quality. Stoak’s range of new oenological tannins are developed with many specific functions, such as modifying antioxidant effects, color stabilization, aroma and flavor enhancement.
