The best iced coffee glass holds your coffee and the ice: plan on 410 to 500 ml for a full cup over ice, or about 300 ml for a short one. Our pick is the Tempo Glass Mug, a 450 ml ribbed borosilicate glass with a bamboo lid and a reusable glass straw. If your iced coffee sits for hours, or sweats on your desk, an insulated steel tumbler does a better job than any glass.

What Makes a Good Iced Coffee Glass?
Room for the ice
A glass full of ice holds roughly half its volume in coffee. So a 300 ml glass serves about 240 ml of coffee with a few cubes, and a 470 to 500 ml glass is what most coffee shops use for a regular iced latte. Pick by the drink you pour, not the number on the box.
Glass or insulated steel
Clear glass shows the drink, the swirl of milk in cold brew, the layers of an iced latte. It holds no flavor and no smell. Its weakness is condensation: a single-wall glass of ice sweats onto the table. Double-wall vacuum steel stops the sweating and keeps drinks cold for hours, but hides the coffee. For hot coffee, see our ranking of the best coffee mugs.
The 6 Best Iced Coffee Glasses and Cups, Ranked
Ranked by how well each one serves a cold coffee you actually drink every day, then by care and looks.
1. Tempo Glass Mug: best overall iced coffee glass
The Tempo Glass Mug is a 450 ml ribbed borosilicate glass with a natural bamboo lid, a silicone seal and a reusable glass straw. It is built for cold brew, iced coffee or anything that tastes better cold, and the lid keeps dust and splashes out when it sits next to a keyboard.
Borosilicate takes temperature changes well: the glass is rated from -20 °C to 100 °C. The glass body and straw go in the dishwasher; the bamboo lid is hand wash only, and its silicone seal comes out once a week for a rinse.
- Capacity: 450 ml, 11.9 cm tall, 8.9 cm across
- In the box: Glass mug, bamboo lid, glass straw
- Care: Glass and straw dishwasher safe; lid hand wash
2. Cascade Clear Tumbler: best large glass for an iced latte
For a full iced latte with plenty of ice, size matters most. The Cascade Clear Tumbler holds 500 ml, with vertical ripples down a clear body and a wide opening that takes ice cubes and a stirring spoon.
It is heat-resistant, so the same glass serves a hot coffee in winter. Let it warm first if it comes out of a cold cupboard, and skip boiling water poured onto a chilled glass. Dishwasher safe on the top rack only.
- Capacity: 500 ml
- Hot or iced: Both, temper the glass first
- Care: Top rack of the dishwasher
3. Canister Glass Cup: best set for sharing
The Canister Glass Cup borrows the shape of an aluminum can and makes it in clear glass. Each holds 410 ml, with a mouth wider than a real can, so it is easy to drink from and easy to fill with ice.
It comes in sets of 2 or 4, stacks well, and goes in the dishwasher on the top rack. Warm coffee is fine; freshly brewed hot pour-over is borderline, so keep it for cold drinks.
- Capacity: 410 ml per glass
- Sets: 2 or 4 glasses
- Care: Dishwasher, top rack, low cycle
4. Riviera Ribbed Iced Glass: best short glass for a strong iced coffee
Not every iced coffee needs a pint. The Riviera Ribbed Iced Glass holds 300 ml, which its product page puts at about 240 ml of coffee plus 4 ice cubes: the right size for an iced Americano. The ribs run the full height of the glass and the base is thicker than the body, so a full glass sits steady.
Each order is one glass, so add the quantity you need. Iced is its home ground; warm coffee works if the glass is warmed first. Top rack, low cycle in the dishwasher.
- Capacity: 300 ml, about 240 ml coffee and 4 cubes
- In the box: One glass
- Care: Dishwasher, top rack, low cycle
5. Atelier Steel Tumbler: best tumbler for iced coffee that lasts all day
If your iced coffee has to last from the morning to the afternoon, glass cannot keep up. The Atelier Steel Tumbler is a 1.2 L double-wall, vacuum-insulated tumbler in powder-coated 304 stainless steel, with an integrated handle, a clear flip-top lid and a reusable straw. Its product page rates it at 8 to 12 hours for cold drinks and 4 to 6 hours for hot ones.
The tapered base still fits standard car cup holders. It is hand wash only, since dishwasher heat damages the vacuum seal. Six colors.
- Capacity: about 1.2 liters
- Temperature: Cold 8 to 12 hours, hot 4 to 6 hours
- Care: Hand wash only
6. Dachshund Insulated Mug: best small insulated cup with a straw
The Dachshund Insulated Mug is a 300 ml double-wall stainless steel cup with a retro dachshund line drawing, a clear lid with a straw port and sealing plug, and a reusable metal straw with a silicone tip. It works for hot or cold drinks and keeps them that way for 1 to 2 hours.
It is a lighthearted pick for a desk and an easy small gift. Hand wash only, so the print does not fade. Five colors: beige, brown, black, grey and silver.
- Capacity: 300 ml
- Temperature: Hot or cold for 1 to 2 hours
- Care: Hand wash only
Two widely sold alternatives, for comparison. We do not stock them.
7. Libbey can-shaped glasses
Libbey, a long-established American glassware maker, sells can-shaped glass tumblers in several sizes. The same idea as our Canister Glass Cup, if you need many pieces for a large household.
8. Stanley or YETI insulated tumblers
Both outdoor brands sell vacuum-insulated stainless steel tumblers with lids and straws. They work on the same principle as our Atelier Steel Tumbler.
How We Chose These Glasses
- Real capacity with ice: each glass is ranked for the drink it holds once the ice is in
- Heat tolerance: heat-resistant or borosilicate glass, so the same cup can take warm coffee
- Lids and straws: for desks, cars and anyone who sips slowly
- Care: dishwasher or hand wash, exactly as the product page says
The two alternatives are well-known options included for comparison, not products we tested next to ours.
Iced Coffee Buying Guide: Match the Glass to the Drink
For the coffee itself, brew it stronger than usual or use cold brew, and try ice cubes made from coffee so the melt adds flavor instead of water. Our guides to cold brew ratios and the best coffee grounds for iced coffee cover the details. More glasses are in the coffee glasses collection.
Four o'clock, and the ice is still there
You filled the glass after lunch: ice to the top, cold brew poured slowly so it threads down between the cubes, a splash of milk turning the bottom into a cloud. Two hours later the glass has left a ring on the coaster, the cubes have rounded at the edges, and the coffee has gone from dark to amber where the milk drifted down. You lift the lid, stir once with the straw, and the last third tastes almost as cold as the first sip.
If you take one thing from this article: buy the glass for the drink plus the ice, about 300 ml for a short iced coffee and 450 to 500 ml for an iced latte, and switch to insulated steel only when the coffee has to stay cold for hours.
Iced Coffee Glasses: Frequently Asked Questions
What size glass is best for iced coffee?
About 470 ml for a regular iced coffee or iced latte, since ice takes up roughly half the glass. A 300 ml glass suits a short iced Americano. If you add a lot of milk or cold foam, go up to 500 ml or more.
Can you pour hot coffee into an iced coffee glass?
Only if the glass is heat-resistant or borosilicate, and even then warm it first and avoid boiling water on a chilled glass. Ordinary glass can crack from thermal shock. Each glass in this guide lists its rule on its product page. For a hot shot, see our ranking of the best espresso cups.
How do I stop my iced coffee glass from sweating?
Condensation forms when cold glass meets warm, humid air. A coaster handles it for a single-wall glass. To stop it completely, use a double-wall vacuum-insulated tumbler such as the Atelier Steel Tumbler, whose outer wall stays at room temperature.
Is glass or stainless steel better for iced coffee?
Glass shows the drink and holds no taste or smell. Insulated stainless steel keeps it cold for hours and does not sweat. Choose glass for drinking at home within the hour, steel for long days, cars and hot weather.
How do I keep iced coffee from getting watery?
Brew it stronger than a hot cup, chill it before pouring over ice, or freeze leftover coffee into ice cubes. Cold brew concentrate, diluted in the glass, also holds up well to melting ice.
Are glass straws safe?
Reusable glass straws are made for daily use. The straw that comes with the Tempo Glass Mug is dishwasher safe. Rinse it right after a milk coffee so residue does not dry inside, and handle it like any glassware.
