A Moscow mule is a cocktail made with vodka, ginger beer, and lime juice; garnished with a slice or wedge of lime, and a sprig of mint. The drink, being a type of buck, is sometimes called vodka buck. It is popularly served in a copper mug, which takes on the cold temperature of the liquid.
Some public health advisories recommend copper mugs with a protective coating (such as stainless steel) on the inside and the lip, to reduce the risk of copper toxicity.
