I just got a few hundred pounds of fresh wine grapes up from Chile (booya!), and I'm thinking repurposing my SS beer keggles for the primary fermentation. Some of the plumbing in the Keggles (it's a HERMS system) is made of copper and brass (e.g., dip tubes, ball valves). Also, one of the keggles has an electric hot water heater element in it. Should I be worried about interactions between the wine must and these metals? I'm only going to use them for primary fermentation, which means the exposure will be 4 days to a week.
