I think only water and especially distilled water with its higher capacity to bond with minerals leaches those materials. Alcohol doesn't leach them, so it is safe to use copper for brewing and moonshining, but I wouldn't want to use them for distilling water. Copper toxicity and biounavailability can cause all kinds of problems, the least of which might be headaches. There all kinds of sites discussing copper toxicity.
This one is interesting.

Copper toxicity is usually due to:
1. excessive supplementation
2. the increasingly common problem of low levels of zinc in the diet
3. contaminated food and drinking water due to contact with metallic copper
4. external exposures such as a copper IUD or accidental 5. agricultural overspray
5. elevated levels of estrogens.

If you still cook in copper pots, you should at least switch to aluminum. Food for thought: The Romans used to flavor their foods with salt, pepper, and lead sprinkles. They thought lead was good for them.
