KeepCup Brew Cork – Natural Cork Meets Glass

The Brew Cork is made from double-wall borosilicate glass, which is strong and resistant to thermal shock. The band is made from natural cork, providing an insulating barrier between the hot glass and your hand. The lid is made from plastic (polypropylene) and the lid seal is silicone.

The glass part of the Brew Cork is dishwasher safe. However, the cork band is not – it should be removed and hand washed to prevent damage. Other models like the Commuter and Original have dishwasher-safe glass and plastic parts, but always check care instructions.

The Thermal keeps coffee hot much longer because it is double-wall stainless steel with vacuum insulation. The Brew Cork’s double-wall glass provides some insulation, but it is not as effective as steel. If you want to extend your drink’s temperature, the Thermal is the best choice.
