Been making wine the last 7 years from grapes and have been using sterilite storage totes to stomp and ferment on the skins. We started small and over the years add more grapes and the party has become bigger and bigger every year. Last year was a close call and the tote just made it to pressing so this year I was considering purchasing metal stock tanks from Home Depot. I know they are typically used to water farm animals but I’m not sure if During fermentation any chemicals from the metal will leach into the wine. Has anyone used these? A simpler solution would be to split the batches and just add more sterilite totes however space in my dining room is limited.
