Effervescent granulated metabisulphite for sulfiting wine in barrels. When added to wine, it rapidly dissolves on the surface of the liquid, assuring that its antioxidant effect is maintained where it is needed. Subsequently, it assures homogenous and rapid distribution of the released SO2 without requiring any bÃÂ¢tonnage. Each packet of Efferbarrique liberates 2 grams of SO2. The pre-dosed packaging reduces the risk of incorrect addition.
