Quick answer

Choose the 7cl Amalfi for espresso or strong shots, and the 20cl for tea, coffee, or cold drinks. The 20cl is more versatile for daily use.

Size matters for your drink ritual

The Duralex Amalfi glass cup comes in two practical sizes: 7cl and 20cl. The smaller 7cl is perfect for espresso, while the larger 20cl suits tea, filter coffee, or even cold beverages. Your choice should match how you drink—not just what looks nice on the shelf.

Both sizes are made from tempered glass, so they handle hot and cold drinks without cracking. The curved design adds a modern touch, but the real difference is capacity.

Tempered glass: safe for temperature swings

Both Amalfi cups are made from tempered glass, which means they can handle sudden temperature changes. This is key if you pour hot coffee into a cold glass or use the cup for iced drinks. The 130°C thermal shock resistance (EN 1183) adds confidence for everyday use.

No matter which size you pick, you get the same durability and style. The decision comes down to how much liquid you typically pour.

Which size should you choose?

  • 7cl for espresso: If you mainly drink espresso or short coffees, the 7cl cup is the right size. It keeps the serving small and strong, just like a traditional espresso glass. Measure your usual coffee portion: if it's under 7cl, this is your match.
  • 20cl for tea and coffee: For tea, filter coffee, or a larger hot drink, the 20cl cup gives you room for a full serving. It also works for cold drinks like juice or iced tea. If you often drink more than 7cl, the 20cl avoids constant refills.
  • Consider your cabinet space: The 7cl cups take less space and are handy for small servings, but the 20cl set is more versatile for guests who prefer different drinks. If you host often, a 20cl set covers most needs; add 7cl if espresso is a staple.
