How to Choose the Right Double-Walled Glasses and Avoid Pitfalls

Double-walled glasses have revolutionised our breakfasts and coffee breaks. Keeping your espresso piping hot or your iced tea perfectly chilled, all within an elegant, airy design: the promise is alluring. However, not all models are created equal. Before you buy, it's best to know the flaws that can turn a promising purchase into a real disappointment. Our editorial team is here to guide you through the options and help you avoid unpleasant surprises.

Here are the 3 most common pitfalls and our tips for avoiding them:

1. Fragility when exposed to thermal shock: The nightmare scenario: you pour your hot coffee, and the glass cracks. This is a classic issue with entry-level models that use ordinary, less-resistant glass. A good glass should be able to handle temperature changes without flinching.
2. Trapped condensation between the walls: This is undoubtedly the most frustrating flaw. During washing, water seeps in through a poorly sealed valve located under the glass. The result is permanent condensation that's impossible to remove, ruining both the aesthetic and the insulation.
3. An elegant but impractical design: A beautiful silhouette isn't everything. Some glasses are unstable, have a rim that is too thick, or are poorly balanced, which spoils the pleasure of daily use.

The Criteria That Really Matter

To ensure you make a smart, long-lasting purchase, there are two points to scrutinise.

1. The Material?: Borosilicate Glass Is a Must-Have

The secret to a glass that lasts? Its composition. Borosilicate glass is the absolute gold standard here. Unlike standard soda-lime glass, it incorporates boron trioxide, which gives it exceptional resistance to thermal shock and scratches. To give you an idea, it's the same type of glass used for laboratory glassware—a true guarantee of sturdiness. By choosing a borosilicate insulated coffee glass, you can be sure it will handle hot, cold, and dishwasher cycles with ease.

2. Craftsmanship and Design?: The Art of Mouth-Blown Glass

The mouth-blown glass technique is an excellent indicator of quality. Each double-walled cup is handcrafted by an artisan, ensuring perfect control over thickness and shape. It is this expertise that creates the famous insulating air layer that keeps your drink at the right temperature.

But be aware, good design is not just about aesthetics. The Scandinavian design, favoured by brands like Bodum, emphasises clean lines and ergonomics designed for everyday use. A successful glass must be lightweight, stable, and comfortable to hold.

Frequently Asked Questions

Are Bodum double-walled glasses really dishwasher-safe??

Yes, most Bodum glasses are indeed dishwasher-safe. However, to preserve their shine and the lifespan of the silicone valve, hand washing with a non-abrasive sponge remains the best long-term option. Be sure to avoid intensive cycles and overly aggressive detergents.

What is the small silicone dot on the bottom of the glass for??

Rest assured, this is not a defect but a technical innovation. It is a hydrophobic silicone valve that equalises the air pressure between the two glass layers. It allows air to escape but prevents water from entering, an essential trick to prevent condensation and ensure the longevity of the glass.

What's the difference between Bodum Pavina glasses and other ranges??

The Bodum Pavina glass model is arguably the brand's most iconic, with its organic, curved shape typical of Scandinavian design. Other collections like Assam (with a handle) or Canteen (straighter and more cylindrical) simply offer different designs and grips to suit all tastes. The manufacturing quality, however, remains the same: borosilicate glass and double-wall insulation.
