Yes. Pure copper has been used for drinkware for centuries. Our unlined pieces are best for water and cold drinks that you enjoy straight away. Don't store acidic drinks (citrus juice, vinegar, wine) or hot liquids in unlined copper for long periods. If you love citrus-heavy cocktails, choose our lined Forge Mule Mug.

Copper chills fast and holds the cold, so the mug frosts over and every sip of ginger beer and lime stays icy. It also looks the part — the mug became the drink's signature in the 1940s.

That's natural oxidation — copper slowly develops a warm, darker patina. Some people love it. To restore the shine, rub with half a lemon dipped in salt (or a paste of baking soda and vinegar), rinse, and dry straight away.

Hand wash with warm water and mild soap, then dry immediately with a soft cloth. Avoid the dishwasher, abrasive scourers and soaking.

Tamra is Sanskrit for copper. In Ayurvedic tradition, water is left in a copper vessel overnight and sipped in the morning — a simple ritual our name comes from.
