Bodum Double-Walled Glasses
These are mugs made of glass with a vacuum-insulated center. Because they are made of glass, you don’t get any metallic taste in your coffee or other beverages. Because they are insulated, you preserve a hot beverage for longer and, for cold ones, you don’t run into condensation problems. Not only that, they look great. The only complaints I’ve ever received about these were that they don’t resemble traditional coffee mugs. You can only lead a horse to water.
