Reusable coffee cup built to preserve brew flavour and cut single-use waste. Natural cork band makes carrying hot drinks comfortable and reassuring for daily commuters. Does the KeepCup Brew Cork Reusable Coffee Cup replace takeaway cups for long-term use?

⚡ At a Glance
  • Brewing Quality: Borosilicate/tempered glass keeps flavours clean and resists lingering smells
  • Best for: Commuters and coffee lovers who prefer glass vessels for taste preservation
  • Not ideal for: People who need a thermal, leakproof travel mug for long journeys

Tempered glass body with a natural cork band and a 340 ml capacity. Dishwasher and microwave safe without the lid and not designed to be thermal or airtight.


Clean, untainted flavour - with a tempered/borosilicate glass body

Glass is non-porous, so brewed coffee does not absorb or retain flavours the way some plastics can. User feedback specifically highlights borosilicate glass for taste clarity and resistance to lingering smells.

Better-tasting coffee on every refill, making speciality brews more enjoyable. Reduced risk of stale or mixed flavours when switching drinks during the day.

Comfortable handling - with a natural cork band

A cork band wraps around the glass, providing a tactile, non-slip surface that cushions the hand. The band is a natural material that sits between the hot glass and skin.

Secure, comfortable grip while walking or commuting, reducing the chance of accidental slips. Cork also adds a warm, familiar feel compared with bare glass.

Practical daily use - with dishwasher/microwave compatibility and replaceable parts

Listing notes that the cup minus the lid is safe for dishwasher and microwave use, while reviews mention an upgraded lid and availability of replacement parts. The lid design includes a sip-through opening and improved sealing.

Quick to clean and simple to reheat drinks, with repair options that extend usable life. Upgraded lid design makes drinking on the move more convenient while reducing waste over time.
