Would those of you who have made Malbec from chilean grapes please describe the aroma? I'm 3 weeks into MLF, and the wine has a smell….not necessarily bad, but distinct. I can't believe it is H2S. Not rotten egg, I've smelled that before on a small amount of wine mixed w gross lees This is different. I was aggressive with nutrients and don't remember smelling it during fermentation. Wine tastes good. As many people that can give me their opinions will help. No one around me makes wine out here….I'm all alone and need some opinions.
