Is stainless steel good for cold coffee and iced lattes?

Yes — stainless steel is ideal for iced coffee and lattes. It’s durable and reusable. The high quality 8/8 electropolished steel used by KeepCup ensures there is no taint to taste and it doesn’t retain flavor, keeping your drink fresh every time. Plus, it’s endlessly recyclable and made to last. Discover more about KeepCup materials and how we prioritize a sustainable supply chain and recycled content.t

What is the best travel mug material for hot and cold drinks?

It depends which you care about more: temperature or taste.

  • Insulated stainless steel: Best for keeping drinks hot or cold for hours. Electropolished rather than ceramic-coated, so there is no flavor taint.
  • Tempered glass: Best for taste. For the delicate flavors of specialty coffee it is hard to go past glass — tactile, beautiful, and it carries nothing forward from the last drink.
  • Lightweight plastic or Tritan: Lightest and most practical for commuting and everyday carry, with 50% recycled content.

If you want one cup that does everything, insulated steel is the safest choice. If coffee is the point, choose glass.

What’s the best material for reusable cups and travel mugs?

The best material depends on your lifestyle. Stainless steel keeps drinks hot or cold for longer, glass gives a clean cafe feel, and lightweight plastic is perfect for on-the-go ease. Every KeepCup is made with durable, food-safe, and recyclable materials designed for daily use.

Can I use my KeepCup Cold Cup for iced lattes?

Absolutely! Whether you’re pouring an oat milk iced latte or a classic iced mocha, the Cold Cup is up for it. Designed to feel like a real cafe cup, it fits neatly under espresso machines and in car cup holders.

Which KeepCup Insulated Cold Cup should I choose?

Both are vacuum insulated, electropolished stainless steel with a central straw valve — no taint, cold to the last sip.

The Commuter Iced Coffee Cup has a screw-fit colored Tritan lid for a more secure, personal carry. The base is also compatible with the Commuter Travel Mug lid and Bottle lid — so one base covers every temperature.

The Thermal Cold Cup has a clear press-in lid. A simpler approach — and you can see exactly what's inside. Sometimes that's the whole point.

Can I microwave my KeepCup Thermal?

While it has a smooth electropolished finish for great taste but NO, you cannot microwave the KeepCup Thermal. None of the KeepCup stainless steel product range can be used in the microwave. If you love to microwave, we recommend KeepCup Brew or our plastic range on low temperature.
