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.

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
