KeepCup Brew Cork Ace – Lighten Your Load

No, KeepCup are not microwave safe. The glass cup can crack or break in the microwave, and the plastic lids and cork bands are not microwave safe. Always transfer your drink to a microwave-safe container before heating.

The Thermal is best for keeping coffee hot for extended periods. For a barista-style cup, the Brew Cork and Brew Cork Ace are great, but they won’t keep coffee hot as long as stainless steel. If you drink your coffee quickly, the glass cups are fine.

The glass parts of the Brew Cork and Brew Cork Ace are dishwasher safe, but the cork band is not. Remove the cork band and wash it by hand. Other KeepCup models have dishwasher-safe components, but always refer to the care instructions.
