Classic double-wall borosilicate mugs

The Kaffe KF4042 set comprises 16oz transparent mugs made from tempered borosilicate glass. The double-wall construction provides heat retention while the exterior remains comfortable to hold. A timeless European-inspired design suits both everyday coffee drinkers and those serving guests.

Suited to black-coffee drinkers and espresso fans

These mugs suit coffee lovers who value heat retention and a clean, modern aesthetic in glassware. They pair well with the Kaffe KF1010 French press and Kaffe coffee grinder for a coordinated ritual. Buyers who need insulated travel mugs with lids or larger-capacity vessels for milk-heavy drinks should consider other formats.

Tempered glass resists thermal shock during daily

Borosilicate glass is tempered for added strength, making it crack and shock-resistant under repeated hot and cold cycles. The material does not react with coffee, preserving flavour over long sessions. The double-wall structure maintains beverage temperature longer than single-wall glass without condensation on the outer surface.

Questions about this item

Do I need a 16 oz brew to fill each mug?

Each mug holds 16 oz, so a standard French press batch or pour-over will fill one cup; scale your recipe to the number of mugs you are serving.

Will the KF1010 French press fit under the mug’s rim?

The double-wall glass mugs have a wide opening that accommodates most French press plungers, including the KF1010, for direct pouring without a separate carafe.

How can I confirm the double-wall insulation is working?

After pouring hot coffee, the outer wall should stay cool to the touch while the drink remains steaming — a clear sign the vacuum layer is intact.
