According to the FDA's Model Food Code, copper should not come into direct contact with foods or drinks with a pH below 6.0, which includes tea. This raises a crucial question for enthusiasts: can I drink tea from a copper cup? The safety of this practice depends heavily on whether the cup is lined with a non-reactive metal and if the liquid is hot.

According to ancient Ayurvedic wisdom, storing water in a copper vessel overnight infuses it with beneficial properties. However, this practice typically involves room-temperature water. A key safety concern arises when heat is introduced, as experts advise against pouring hot beverages into unlined copper cups, confirming a definitive answer to the question: Can you drink hot beverages in a copper cup?.

Over time, pure copper naturally develops a protective patina, or tarnish, when exposed to air and moisture, leading many to wonder if their copper cups go bad. The good news is that copper drinkware doesn't technically expire, but it does require proper care and safe usage to remain functional and hygienic for many years.
