Choosing double-walled glasses: how to avoid a disappointing purchase

Coffee that cools too quickly, hot fingers on a glass or condensation rings on the table: these are familiar problems with ordinary glasses. Double-walled glasses can help reduce these inconveniences, but not every model suits every drink or household. Marketing terms such as “thermal”, “heat-resistant” and “suitable for all temperatures” also don’t always tell you enough about everyday use.

So focus on capacity, material and which appliances the glasses can be used with. Read on to find out what to look for and which models suit different needs.

Common pitfalls when choosing double-walled glasses

1. The capacity doesn’t suit your drink

An 80 ml glass is practical for espresso, a small dessert or a strong coffee. It’s usually too small for cappuccino, latte or cold drinks. Conversely, a 450 ml glass can be awkwardly large for an espresso.

So look beyond the shape and check the actual capacity. Allow room for milk froth, ice cubes or layers of dessert.

2. “Heat-resistant” doesn’t mean unbreakable

Borosilicate glass is known for how well it handles changes in temperature. Even so, it’s still breakable. For example, don’t pour boiling water into a glass straight from the fridge. Also check whether the product is explicitly suitable for the microwave, oven, freezer and dishwasher. These features can vary between collections and sizes.

According to Bodum’s product information, various PAVINA, BISTRO, SKÅL and CANTEEN models are suitable for these appliances within a specified temperature range. That doesn’t mean every double-walled glass can be used in the same way.

3. A condensation-free exterior depends on the conditions

The double wall is designed to make the outside feel less hot or cold and to limit condensation. With a very cold drink, high humidity or prolonged use, moisture can still form. So think of “condensation-free” as a benefit of the design, not an unlimited guarantee in every situation.

Which specifications matter?

Material: borosilicate glass or tempered glass

Many thermal glasses are made from borosilicate glass. Product descriptions often associate this material with a lighter weight and resistance to temperature changes. According to the manufacturer, the Bodum models in this guide are mouth-blown from heat-resistant borosilicate glass.

Other models, such as the DeLonghi DLSC311, use tempered glass. According to the product information, it’s designed to offer extra resistance to thermal shock. Be sure to check appliance compatibility for this model: the listed specifications say it’s dishwasher-safe, but don’t mention whether it’s suitable for the microwave or freezer.

Capacity and shape

Use these guidelines as a practical starting point:

  • 80 to 150 ml: espresso, ristretto and small desserts;
  • 190 to 280 ml: cappuccino, regular coffee, tea and smaller cold drinks;
  • 400 to 450 ml: café latte, large cups of tea, cold brew or layered desserts.

A straight tumbler is handy for cocktails, soft drinks and tea. A handled cup is more comfortable to hold when drinking cappuccino or latte. Also check the diameter if you want to place the glasses under a coffee machine.

Care and temperature limits

Always check the product specifications rather than relying on the words “dishwasher-safe” alone. According to the manufacturer, some models are also suitable for the oven and microwave, but only up to a limit such as 176 °C or 180 °C. Don’t put a glass straight from the freezer into a hot oven, and avoid sudden changes in temperature.

A small silicone valve or an opening on the base may be part of the design. According to the product description, this helps equalise the pressure between the two layers of glass. Don’t try to remove or damage it.

Frequently asked questions about double-walled glasses

Are double-walled glasses dishwasher-safe?

It depends on the model. Many Bodum PAVINA and BISTRO glasses are described as dishwasher-safe. Always check the specifications for your exact version, and don’t put damaged glasses in the dishwasher.

Can thermal glasses go in the microwave?

Some double-walled glasses are described by the manufacturer as microwave-safe, but that doesn’t apply to every thermal glass. Check the maximum temperature too, and avoid sudden changes in temperature.

How long do double-walled glasses last?

How long they last depends on how you use and clean them, and how you handle changes in temperature. Borosilicate or tempered glass can be practical for hot and cold drinks, but both materials can break if dropped, knocked or exposed to thermal shock. Don’t use a glass with a crack, chip or damaged base.
