Description
Judge 2-piece Duo latte glass set, 325ml
Tall, gently tapered and holding 325ml apiece, this is Judge's original Duo latte glass, the shape the whole range started from before the rounder Form and wider Flare versions arrived.
Two tall, gently tapered glasses make up this set, each holding 325ml and individually mouth-blown from borosilicate glass, so no two are ever quite identical. It's the original shape in Judge's Duo range, designed for anyone who takes their coffee at home seriously but doesn't want a cupboard full of mismatched mugs, with a profile built to show a latte's layers as it's poured.
What stands out is the double-walled construction: an insulating air pocket between two layers of glass keeps a hot drink hot for longer while the outer surface stays cool enough to hold without a handle burn. The same air pocket stops iced coffee from sweating onto the table, so there's no ring left behind and no coaster required.
Ideal For
Anyone who makes milky coffee at home will get more from a glass that's actually sized for a latte, with a shape built to show its layers.
The double-walled glass works either way, keeping a hot latte hot and an iced coffee cold without condensation running down the outside onto the worktop.
Each glass is individually mouth-blown, so a set makes a genuinely distinctive gift for someone who already owns every standard mug a kitchen could need.
Key Features
Each glass holds 325ml, enough for a full milky latte poured over espresso without filling the glass right to the brim.
Two layers of glass trap an insulating air pocket, keeping drinks at temperature for longer while the outside of the glass stays cool to hold.
Made from borosilicate glass for strength and clarity, so the layers of a latte stay visible through a glass that resists everyday scratches.
Each glass is individually mouth-blown by hand, which means small natural variations between the two pieces rather than machine-perfect uniformity.
Both pieces go straight into the dishwasher or microwave, so there's no separate hand-washing routine or special care needed day to day.
Rated by Judge for temperatures up to 100°C, so the glass copes easily with fresh-off-the-hob coffee or tea without any special handling.
A shape built for latte layers
Pour a latte into a clear glass and the layers do the talking: dark espresso at the base, steamed milk through the middle, foam on top. The Duo latte glass is shaped and sized specifically for this, at 325ml, so there's room for a full milky coffee without the glass looking half-empty or overflowing. It's a small detail, but one that changes how an everyday coffee actually looks and feels to drink, at home rather than only in a café.
Why the glass stays cool to hold
The trick is in the wall, not the drink. Two layers of borosilicate glass are fused with a sealed air pocket between them, and that trapped air is a poor conductor of heat. Hot coffee heats the inner wall, but very little of that heat reaches the outer surface, so the glass can be picked up by the body rather than just the handle moments after pouring, without the sharp heat you'd get from a single-wall glass or mug.
This glass's place in Duo
Judge sells more than one 325ml latte glass under the Duo name, and this is the original: a tall, gently tapered shape without a sub-range name attached, sitting alongside the shorter, rounder Duo Form latte glass and the wider, tapered Duo Flare latte glass. All three share the same capacity and the same double-walled, mouth-blown construction, so the choice between them comes down to which silhouette suits the table, not which one performs better. This is the straightforward, classic option of the three.
How It Compares
| Kitchen Need | Judge Feature | Practical Benefit |
|---|---|---|
| Milky coffee at home | 325ml double-walled glass | Sized for a full latte with room for steamed milk, and shaped to show its layers as you pour. |
| Iced coffee in summer | Insulated air-pocket wall | Keeps a cold drink cold without condensation forming on the outside of the glass. |
| No coasters to hand | Cool-to-touch exterior | The outer glass stays cool even with hot coffee inside, so there's no ring left on the table. |
| Everyday washing up | Borosilicate glass construction | Dishwasher and microwave safe, so cleanup is no different from any other glass in the cupboard. |
| Gifting a coffee lover | Hand-blown borosilicate glass | Each glass is individually mouth-blown, so a set has a handmade quality mass-produced glassware doesn't. |
| Straight off the machine | Heat resistant to 100°C | Copes with fresh-brewed coffee at temperature without any special handling before it cools. |

The Verdict
Strengths
- 325ml capacity suits a full milky latte
- Double-walled glass keeps drinks hot, exterior cool
- Individually mouth-blown, so no two pieces are identical
- Borosilicate glass for strength, clarity and scratch resistance
- Dishwasher and microwave safe for easy everyday use
- Rated heat resistant up to 100°C
- No condensation on iced drinks, so no coaster needed
Considerations
- As hand-blown pieces, each glass is individually formed, so slight variation in size or finish between the two is normal, not a fault.
- Heat resistance is stated up to 100°C, so these are meant for hot drinks and washing up, not stovetop, oven or open-flame use.
- This is the plain Duo latte glass rather than the Form or Flare version, so check the shape in the photos matches what you want.
