📹 What are the Best Cups and Mugs to Keep Coffee Hot?

Learn how common types of drinkware fare when determining the best coffee mugs to keep coffee hot all day.

We did a heat retention test on a standard ceramic mug, a single-walled glass mug, a Bodum Bistro double-walled glass mug, a double-walled vacuum-insulated stainless steel Camelbak Camp Mug with and without a lid and a standard paper to-go cup with a lid to see which is the best at keeping drinks warmer, for longer. All of the cups were left out on the counter overnight and were not preheated. We poured 6 ounces of freshly brewed coffee into each one and recorded how the temperature changed over 2 hours.


At the start of the test, all of the samples started out at 170 degrees Fahrenheit. 

Temperature (°F) 2 hours after brewing:

  • 124°: Camelbak double-walled, vacuum-insulated stainless steel Camp Mug with a lid 
  • 92°: Camelbak double-walled, vacuum-insulated stainless steel Camp Mug without a lid
  • 80°: Bodum Bistro double-walled glass mug
  • 80°: Ceramic Mug
  • 80°: Single-walled glass mug
  • 80°: Paper to-go cup with a lid


Regardless of the material, we recommend preheating your cup or mug to keep your coffee hotter for longer. Some espresso machines have a built-in cup warming tray, which makes pre-heating a no-brainer. If your machine doesn’t have a cup warming tray, just rinse your desired cup or mug with hot water before brewing.
