Glass mug ritzenhoff & breker Doppio anthracite 320 ml – double-walled coffee mug

The ritzenhoff & breker Doppio anthracite 320 ml is a double-walled glass mug designed for serving coffee and other hot beverages. With a 320 ml capacity it accommodates doppio servings or larger portions while the clear double-wall construction provides visual appeal and thermal insulation. The anthracite-colored handle and rim detail combine with transparent glass to create a modern, restrained look suitable for home, office or café settings. The double-walled design reduces heat transfer to the outer surface, helping to keep the beverage warm while the exterior remains comfortable to hold.

Advantages

The double-walled borosilicate-style glass construction offers improved thermal insulation compared with single-wall glass and helps preserve drink temperature for longer. The 320 ml volume is versatile for espresso-based doppio drinks, filter coffee, tea or other hot beverages. The transparent body showcases crema and layering in coffee while the anthracite accents add a neutral aesthetic that fits many table settings. The mug is designed for everyday use and is dishwasher-safe according to manufacturer guidelines for convenient cleaning.

How to use

Pour freshly prepared coffee or other hot beverage into the mug up to a suitable fill level, allowing space for crema or milk foam as needed.

Inspect the glass for chips or cracks and discontinue use if damage is present.

Recommendations

For best results, pre-warm the mug briefly with hot water before pouring coffee to maintain optimal serving temperature. Avoid sudden temperature changes and use dishwasher cycles recommended by the manufacturer to preserve the finish and thermal performance.
