I found this additive on the beverage people’s website. It is supposed to help with VA . I have a Carmenere from last year that smelled like nail polish in December I hit it hard with pot meta a few months ago (100ppm)and it does smell a lot better. So2 is now 48 ppm. I’m going to try this additive and wondered if any of you have tried it?
