Double Wall or Tempered? Picking the Best Coffee Mug Glass

A glass mug shows you the coffee: the crema on an espresso, the layers in a latte, the exact moment the milk turns a café con leche the right shade of tan. It also keeps no smells from yesterday’s cup. The catch is heat. Ordinary glass can crack when boiling liquid hits it, and some glass “coffee mugs” sold online are, by their own makers’ fine print, meant for warm drinks only.

This guide sits under our coffee mug guide, which covers ceramic mugs and already includes one double-wall glass set. Here we look only at glass: double-wall borosilicate mugs that keep the outside cool, and thick single-wall mugs made from tempered or heavy glass. For each one we report what the maker says about the microwave, the dishwasher and heat shock, and we say plainly when a maker says nothing.

Quick verdict: which glass coffee mug to buy

Below are the five strongest picks side by side, then all eight in detail, then what to check before you buy any glass mug for hot coffee.

Five glass coffee mugs side by side

Five standout picks, one for each kind of coffee drinker, with what each maker or listing says about microwave use. All eight mugs are reviewed in full below.

Our picks for the best coffee mug glass

These eight cover the two kinds of glass mug worth buying for hot coffee. Double-wall borosilicate mugs trap air between two thin layers, so the outside stays cooler and the coffee is held a little longer. Single-wall mugs in tempered or thick glass are heavier and simpler, and they cost less per mug. We left out glass mugs whose own listings say they are for warm drinks only or are not microwave safe, because that is not what most people want from a coffee mug. Our coffee mug guide already recommends the Bodum Bistro 15 oz mug, so it is not repeated here.

How to choose a glass coffee mug

Glass is less forgiving than ceramic, so the details matter more. These are the things a kitchen checks before buying glass for hot drinks.

1. Read the hot-liquid fine print

Some glass mugs sold as “coffee mugs” are, by their makers’ own words, for warm drinks only and not for the microwave. Libbey’s Kona, Tapered and Cavana listings all say so. That is fine for an Irish coffee or a milkshake, but not for coffee straight from the pot. Look for borosilicate, tempered or heat-resistant glass, and for a listing that names hot drinks.

2. Double wall or single wall

Double-wall mugs keep the outside cool, stop condensation and hold heat a little longer, but the glass is thin. Single-wall tempered or thick glass is sturdier and cheaper, but the outside gets hot, so a handle matters more. A double-wall mug with a handle, like the Luigi Bormioli or Zwilling, gives you both.

3. Heat shock limits

Glass cracks when one part heats or cools much faster than another. Makers that publish a figure give different kinds: Bodum lists a working range of -30°C to 180°C for the Canteen, Duralex rates its tempered glass for a 130°C thermal shock, and Kinto gives a 120°C maximum temperature difference. None of those means you should pour boiling water into a mug straight from the freezer. Let a cold mug warm up first, or rinse it with warm water.

4. Microwave and dishwasher

Most picks here are listed as dishwasher safe. Microwave safety varies: Luigi Bormioli, Zwilling, Duralex, Bodum’s Pavina and Kinto say yes, while Libbey’s Robusta, the Bodum Canteen with handle and the Bormioli Rocco Oslo do not say. Never microwave a mug with a metal handle, and do not heat any glass mug empty.

5. Decorated glass

Every mug on this page is clear, undecorated glass. If you buy a glass mug with a printed design or a colored rim, look for the maker’s statement that the decoration is lead- and cadmium-free, and check whether the print is dishwasher safe. If the listing says nothing, ask the seller or choose a plain mug.

How we picked these eight glass mugs

We started from what a cook wants from a glass mug for hot coffee: glass made for heat, a sensible size, and clear care rules. We took capacity, materials, microwave and dishwasher statements from each Amazon listing, and heat limits and country of origin from the makers’ own pages where they publish them (Zwilling’s product page, Duralex’s glass information pages and Kinto’s product pages). Every mug was in stock on Amazon when we checked, and every maker is an established glassware company. We have not used these mugs for this guide; heat and care claims are the makers’.

We searched the U.S. Consumer Product Safety Commission’s recall list for every brand here. We found no recall for any of these mugs. Bodum’s recalls were for coffee presses (most recently, in October 2026, about 5.9 million French presses with replaceable glass carafes), a stovetop espresso maker and toasters, Libbey’s for other glassware (milk bottles, bourbon and cocktail glasses), and Zwilling’s for an electric kettle. We left out JoyJolt’s double-wall mugs: the brand’s single-wall Declan glass coffee mugs were recalled in June 2024 because they could break when filled with hot liquid, and with plenty of other choices we preferred makers without a glass-mug recall. We also left out the Bodum Bistro mug that already appears on our coffee mug guide, and Hario’s and Kinto’s other glass mugs, which were not reliably in stock.

Glass for café de olla and café con leche

A clear mug suits the coffee drinks of a Mexican kitchen. Café de olla, simmered with piloncillo and a stick of canela, turns a deep amber you can see through the glass, and a café con leche shows its color as the milk goes in. Strain café de olla well before pouring; grounds settle at the bottom of a clear mug where everyone can see them. For milk drinks, a milk frother makes foam that looks best in a tulip glass like the Oslo.

Glass coffee mug questions, answered

What is the best quality glass coffee mug?

For double-wall glass, the Luigi Bormioli Thermic Glass mug, which its maker lists as thermal shock resistant and safe in the microwave and dishwasher. For a sturdier single-wall mug, Duralex’s tempered Cosy mug.

Are glass coffee mugs safe for hot coffee?

Mugs made from borosilicate, tempered or heat-resistant glass are made for hot drinks, according to their makers. Some ordinary glass mugs are listed for warm drinks only, so read the listing before buying.

Can you put a double-wall glass mug in the microwave?

Some, yes: Luigi Bormioli, Zwilling, Bodum’s Pavina and Kinto list theirs as microwave safe. Do not heat one empty, and check the listing for the exact model, as Bodum’s handled Canteen listing does not say.

Why do double-wall glasses have a hole in the bottom?

Bodum’s Canteen has a small silicone valve that equalizes the air pressure between the two layers of glass as the air inside heats and cools. Keep it intact; do not pick at it.

Do glass mugs keep coffee hot?

Double-wall glass holds heat a little longer than a single wall and keeps the outside cooler, but it does not keep coffee hot for hours. For that, see our guide to insulated coffee mugs to go.

Our final pick for glass

Buy the Luigi Bormioli Thermic Glass mug if you want a double-wall glass mug with a handle and clear microwave and dishwasher rules. Choose the Duralex Cosy for toughness, the Zwilling set for four matching double-wall mugs, the Libbey Robusta to fill a cupboard, and the Kinto or Bormioli Rocco Oslo for smaller coffee drinks. For ceramic mugs, see our coffee mug guide; for tea, the tea infuser mug guide includes a double-wall glass mug with an infuser. And if you would rather have someone else make the coffee and breakfast, see the menu or call to order.
