What materials are best for keeping coffee hot in a mug?
The best materials for keeping coffee hot are stainless steel, ceramic, and double-walled glass. Stainless steel mugs tend to have excellent insulating properties, especially when they feature a vacuum-sealed design. This prevents the heat from escaping and keeps your coffee hot for an extended period. Ceramic mugs, while not as insulating as stainless steel, can retain heat effectively due to their thickness and density, making them a popular choice among coffee lovers.
On the other hand, double-walled glass mugs are aesthetically pleasing and can also provide decent insulation by trapping air between the two layers of glass. This design helps keep your coffee hot while allowing you to enjoy the visual appeal of your drink. However, it’s essential to choose well-made products from reputable brands to ensure they provide the thermal performance you seek.
