Bodum Double-Walled Glasses: A Buying Guide to Avoid Common Pitfalls

A cup of coffee or tea is more than just a beverage; it's a personal moment. Presentation matters, and Bodum's double-walled glasses are popular for their stylish, 'floating' effect. However, not all double-walled glasses are created equal. Before you invest in a new set, it's wise to know what to look for. A few common issues can significantly detract from your enjoyment.

The 2 most common pitfalls of double-walled glasses:

1. Leakage and Condensation: The most frequently reported issue is water getting trapped between the two glass walls after washing. This leads to unsightly stains and a permanently fogged appearance. The culprit is often a poorly sealed silicone valve at the base.
2. Unexpected Fragility: Although they look robust, double-walled glasses can be surprisingly fragile. A minor tap against the faucet or awkward placement in the dishwasher can cause a crack, especially with glasses of inferior quality.

Making the right choice depends on the material, construction, and how the glass fits into your daily routine.

What to Look For to Make a Lasting Choice

To avoid having to replace your glasses after just a few months, there are a few technical specifications that make all the difference. By paying attention to these details, you'll select a product built for everyday use.

1. Material: The Importance of Borosilicate Glass

Most high-quality heat-resistant glasses, including those from Bodum, are made from borosilicate glass. This is not your standard glass. It has a different chemical composition that makes it lighter, stronger, and far more resistant to thermal shock. This means the glass won't crack when you pour boiling water into it. It's a crucial feature for both double-walled tea glasses and double-walled coffee glasses.

2. Construction: The Silicone Valve and Finish

At the bottom of every Bodum glass, you'll find a small silicone dot. This is not a manufacturing defect. It's a hydrophobic silicone valve that equalises the air pressure between the two glass layers. When you pour in a hot or ice-cold beverage, the air between the walls expands or contracts. Without this valve, the pressure could cause the glass to shatter. The quality of this valve determines whether the glass remains waterproof during washing. Bodum states that their valves allow air to pass through but keep water out.

3. Model and Size: PAVINA vs. BISTRO

Bodum offers several series, with PAVINA and BISTRO being the most well-known.

• Bodum PAVINA: These are the classic, rounded thermo glasses without a handle. They are available in various sizes, from small double-walled espresso glasses (80 ml) to larger sizes for lattes or cold drinks. The new PAVINA PARIS line features a fluted exterior for extra grip.
• Bodum BISTRO: This line is characterised by its glasses with a handle. They function more like a traditional mug, which many people prefer for their morning coffee. They offer the heat-insulating benefits of a double-walled glass with the familiar grip of a handle.

The choice between these models is purely personal and depends on how you prefer to drink your coffee or tea.

Frequently Asked Questions

1. Can Bodum double-walled glasses really go in the dishwasher? Yes, according to the manufacturer, most Bodum double-walled glasses are dishwasher-safe. However, it is advisable to place them carefully in the top rack, with enough space to avoid contact with other dishes. This minimises the risk of damage. The silicone valve is designed to be waterproof, but aggressive dishwasher cycles can pose a risk in the long term.

2. Why is there a small hole with silicone on the bottom of my glass? That is the hydrophobic silicone valve, an essential part of the design. It allows air to escape or contract to regulate the pressure between the glass walls as the temperature changes. This prevents the glass from shattering under pressure. It is designed to let air pass through but keep water out. Do not attempt to remove or puncture the valve.

3. How long do double-walled glasses last? The lifespan depends heavily on use and care. Borosilicate glass is stronger than regular glass, but it is still glass. Major thermal shocks (like putting an ice-cold glass under a hot tap) and hard impacts can damage it. With careful handling, such as handwashing or gentle placement in the dishwasher, a set of double-walled glasses can last for years.
