A 6-piece glass set may seem straightforward at first glance: six matching or colour-coordinated glasses, a suitable capacity and an appealing design. In practice, however, small differences in material, height, insulation and care requirements can quickly lead to unsuitable purchases. A drinking glass that is suitable for water is not automatically suitable for hot drinks, cocktails or the dishwasher.
Our buying guide explains what households, design enthusiasts and hosts should look for when shopping. It focuses on objectively verifiable product details rather than marketing claims.
An 80 ml glass is suitable for espresso, liqueur or small tastings, but not as a water glass for an entire evening. A 400 ml glass, on the other hand, offers more capacity for water, juice or long drinks, but also requires more space in the cupboard and dishwasher.
So pay attention to the actual capacity of each glass:
Double-walled glasses and thermal glasses have two layers of glass with a gap between them. This means the outer surface may behave differently with hot or cold drinks than it would with single-walled glasses. The design also reduces visible condensation from cold drinks.
Even so, you should check whether the manufacturer has specifically approved the glass for hot drinks. A double-walled construction does not replace clear care and usage instructions.
“Easy to clean” does not automatically mean dishwasher-safe. Some products are expressly approved for cleaning in the dishwasher, while hand washing is recommended for others. Coloured surfaces and delicate shapes may also require more careful handling.
Before buying, the following information should be available:
Glass is standard for classic water glasses. Borosilicate glass is often used for double-walled models. This material is listed in the product details for the BODUM CANTEEN 0.2 l and 0.1 l. Even so, the specific approval for each product remains decisive.
Porcelain is particularly suitable for small hot drinks. The Bialetti espresso cups are made from porcelain, have handles and hold 90 ml each. They are therefore more like espresso and spirit glasses, or small cups, than classic drinking glasses.
A low glass is often suitable for water, juice and short drinks. A tall, narrow long drink glass set, on the other hand, is designed for soft drinks, cocktails and mixed drinks. The shape also affects how much space the glasses take up in the kitchen cupboard.
If you are looking for a versatile water glass set, consider a capacity of between 250 and 350 ml. For larger servings or plenty of ice, a 400 ml model may be more practical.
Dishwasher-safe glasses save time in everyday life. Even with double-walled glasses, you should follow the manufacturer’s instructions and avoid sudden temperature changes. A thin glass may be more vulnerable to knocks than a simple, thick-walled model, even when it is suitable for dishwasher cleaning.

We have put together a complete, regularly updated list of products that fully meet these strict selection criteria and the safety regulations applicable in the EU.
For everyday use, 250 to 350 ml is often practical. 200 ml is enough for smaller servings, while 400 ml offers more room for ice, juice or large amounts of water. The shape of the glass, cupboard height and space in the dishwasher are also important factors.
That depends on the manufacturer’s information for the specific product. The BODUM CANTEEN glasses are stated to be suitable for hot and cold drinks. With other double-walled glasses, you should check the product description and care instructions before pouring in coffee or tea.
It is not possible to give a reliable fixed lifespan. This depends on the thickness of the material, impact, temperature changes and the dishwasher programme. Glasses should be positioned with space between them and away from cutlery and other crockery. For products without dishwasher approval, hand washing is the intended method of care.
