Double-walled glasses combine a sleek, clear look with an insulating construction. Depending on their size, they are ideal for espresso, coffee, tea, cocktails or water. However, when buying, it is not just the modern design that matters. The material, capacity, cleaning requirements and temperature resistance information all determine whether a set will truly suit your daily habits.
A 250 ml glass works well for smaller servings, whereas 350 to 450 ml is better suited to larger coffees, tea or cold drinks. For espresso, 70 to 150 ml is typical. A glass that is too large can make an espresso look lost; a vessel that is too small can be impractical for tea or long drinks.
Also, check whether the stated capacity refers to the brim or the usable volume. These figures are not always the same.
Double-walled thermal glasses are often made from borosilicate glass. This material can handle temperature changes, but a hard knock or an extreme temperature shift can still cause damage. Therefore, a glass should not be filled directly from the freezer with boiling water.
If glasses are damaged with cracks or chips, it is not sensible to continue using them. The double-walled construction can also be more sensitive to impacts than a simple drinking glass.
'Dishwasher-safe' makes cleaning easier, but it does not mean the surface will remain unchanged under every programme. Harsh detergents, high temperatures and frequent cycles can affect the clarity of the glass over time.
So, check the specific manufacturer's instructions. Soft sponges and a gentle programme are a sensible precaution for high-quality double-walled drinking glasses.
Borosilicate glass is a heat-resistant glass with relatively good thermal shock resistance. In double-walled glasses, it often forms both the inner and outer wall. The insulating layer of air between the two walls reduces direct heat transfer and can make the outside feel more comfortable to hold when serving hot drinks.
This does not mean the glass is suitable for the oven. The microwave, oven and freezer should only be used if this is explicitly stated for the particular model.
Double-walled espresso glasses should fit comfortably under the spout of your coffee machine. If necessary, measure the height and diameter of the glass.
For dishwasher-safe glasses, the product description should be clear. For daily use, a stable base, a comfortable rim and a shape that is easy to grip are also important. Not every double-walled glass is stackable, which can be a key factor in smaller kitchens.
With sets, you should also check whether two or more glasses are actually included and whether all pieces have the same capacity.

We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations in force in the EU.
Many models are designed for coffee and tea, particularly those made from borosilicate glass. The specific manufacturer's instructions are key. Even heat-resistant glasses should not be subjected to sudden temperature changes.
If they are labelled as dishwasher-safe, they can be cleaned in the machine. A gentle programme and mild detergents can help preserve the glass surface in the long term. If the instructions are unclear, hand washing with a soft sponge is the safer option.
For espresso and ristretto, around 70 to 100 ml is usually suitable. Double-walled espresso glasses with 7 cl, such as the Cléa set, are designed for small servings. For larger milky coffees or tea, choose a model with at least 200 ml.
