Heads up, Moscow mule lovers: That copper mug could be poisoning you

The Moscow mule — that Instagram-ready cocktail that has surged in popularity in recent years — has only a few ingredients: vodka, ginger beer, lime and ice. But perhaps the most crucial component of the drink is the copper mug in which it’s almost always served, beverage aficionados say.

Now, public health officials are warning that those mugs could be poisoning you.


An advisory bulletin from Iowa’s Alcoholic Beverages Division notes that, in keeping with Food and Drug Administration guidelines, copper should not come into contact with acidic foods with a pH below 6. That includes vinegar, fruit juice, wine and, yes, a traditional Moscow mule, whose pH is “well below 6.0.” the bulletin says.

“When copper and copper alloy surfaces contact acidic foods, copper may be leached into the food,” the division notes.
