I have never made wine before. I have made beer however. Anyway, I got a kit for christmas, and I was reading through the instructions. If I want to age the wine for over 6 months it says to add 1.5 grams of Potassium Metabisulphite to my wine before bottling. I don't have a scale, anyone know how much that is in another measurement? Also, does that sound right to you and how long will that allow me to age my wine before it starts to get funky?
