Anyone hear of or try this? Efferbarique SO2
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 b√¬Ętonnage. Each packet of Efferbarrique liberates 2 grams of SO2. The pre-dosed packaging reduces the risk of incorrect addition.
Package: Box of 40 packets,
My Carlson Kmeta seems to fade fairly quickly so i thought this might be the answer
seems like a good idea but the shipping cost is almost as much as the item.
