I hope I did not introduce metallic contamination. I used a metal soup pot for the primary fermenter. I’ll have to find out if it is stainless steel; I doubt it. Also, I used a sterilized metal soup spoon to stir the must; should have used a long plastic food-grade spoon or glass rod. The metal may have introduced a colored haze to the wine.
The soup pot and metal spoon were stainless steel, which is ok. Wooden spoons are discouraged because they are difficult to keep sanitized. Next time I’ll use food-grade plastic spoon.
