If you're a fan of a well-crafted Moscow Mule (and if you're not, you should be), you should know that tradition dictates they're served in a copper mug. The metal chills way down for a cooling sensation appropriate for top-shelf vodka, and mixology pros say that the chilled copper can also boost the liquor's aroma, stimulate the carbonation of ginger beer for extra fizz, and highlight a lime's citrus zing to tie everything together.
These ones use pure, 100% recycled copper with a solid weld from handle to body. The heavy-gauge hammered metal will last for generations, and has got a durable shine that looks as good as your drink will taste.
Wash and dry immediately after drinking to prevent the copper from spotting. Some people don't mind it, and let the copper slowly and subtly tarnish into a one-of-a-kind patina as a testament to all those expertly made drinks. But if you want to get it back to a bright shine, just give it a quick polish.
