Hello All! While racking an extremely clear "sparkling" PINK Strawberry-Watermelon wine (5 Gals), it turned BROWN in the racking cane/hose! Right before my eyes as it was transferring! Pink in the transfer from carboy to brown in the transfer-to? I would think oxidation but doesn't this typically occur over time? There was no (to my knowledge) air in the racking cane/hose. It has a nice straw/melon aroma & tastes pretty good! (I will need to sweeten a bit). Anybody have this happen or know if it's normal or indicates a problem?
