A cup of coffee that's lukewarm before you've even settled down, or condensation rings on your new wooden table. These are small, daily annoyances. Double-walled glasses seem like the perfect solution: they look sleek and promise to keep your drink at the right temperature for longer. But not all glasses live up to that promise. Before you invest in a new set, it's wise to know what to look for.
Many glasses that look beautiful online turn out to be impractical or fragile in reality. Two common pitfalls are:
A good choice depends on a few technical details that manufacturers don't always clearly disclose.
To avoid having to replace your glasses after just a few months, there are three key points to check. These determine the quality and lifespan of your Bodum double-walled glasses.
The type of material is crucial. Many high-quality heat-resistant glasses, including those from Bodum, are made from borosilicate glass. This is not your standard glass. It is lighter in weight, yet simultaneously much stronger and more resistant to thermal shock. This means the glass won't easily crack when you pour boiling water into it or move it from the dishwasher directly to a cold cupboard. It's the standard for laboratory glassware, and for good reason.
At the bottom of many Bodum glasses, you'll find a small, inconspicuous silicone dot. This is not a manufacturing defect. It's a hydrophobic (water-repellent) valve that allows air to pass through but keeps water out. When you pour a hot or ice-cold drink into the glass, the air pressure between the two glass walls changes. This valve equalises that pressure, reducing the stress on the glass. This prevents the glass from cracking and, more importantly, helps keep moisture out of the double wall. Glasses without this technology are more susceptible to internal condensation.
A good glass is both functional and beautiful. Pay attention to the shape: does it feel comfortable in your hand? Is the base stable enough? The designer glasses from Bodum, such as the Bodum Pavina series, often feature a thoughtful ergonomic design. Versatility is also a factor. A well-designed glass is suitable for a cappuccino or latte macchiato, but can just as easily be used for a cold soda, a cocktail, or even a dessert. This way, you don't need a different type of glass for every occasion.
Based on these criteria, we have selected a few options that suit different needs and usage scenarios.

Yes, most double-walled tea glasses and coffee glasses from Bodum are dishwasher safe. This is made possible by the use of borosilicate glass and the pressure-regulating valve. However, it is always wise to check the product information for the specific model, as recommendations may vary.
That 'hole' is an essential part of the design. It is a water-repellent silicone valve. It allows air to escape or contract when the temperature inside the glass changes, which stabilises the pressure between the glass layers. This prevents the glass from cracking and keeps moisture out, so you won't have issues with condensation between the walls.
Although borosilicate glass is significantly stronger and more temperature-resistant than normal glass, it is still glass. They are designed for everyday use, but a hard knock against a granite countertop or a drop onto a tile floor can still cause a crack. Treat them with the same care you would your other glassware, but rest assured that they are more resistant to the stress of temperature changes and minor taps.
