This Is How Long The YETI Rambler 20 oz. Tumbler Keep s Coffee Warm?

Advertisements

I recently got a YETI Rambler 20 oz. Tumbler as a birthday gift. I was excited because I had already been really impressed with the YETI Rambler 14 oz. Mug, but was bummed because it doesn’t work very well to take on the road. The mug is too big for the cup holders in my car, so I found myself never taking it with me.

The 20 oz. Tumbler is the perfect to-go size and is even advertised on the packaging to fit into any cup holder in your car, or even boat.

I noticed that the Tumbler was doing a great job all throughout the day, so I thought I’d do an experiment to see how long the YETI Tumbler could keep my coffee warm.

Setting up the Experiment

Around 8:30 in the morning, I brewed a cup of coffee on my Ninja Coffee Bar right into the Tumbler. Roughly every half hour, I checked the temperature using an instant read thermometer called the ThermoPop by ThermoWorks.

Check out the full video of the experiment here:

The Results

• 8:35 a.m.: 178° F (this was immediately after brewing)
• 9:38 a.m.: 159° F
• 10:19 a.m.: 151° F
• 10:50 a.m.: 145° F
• 11:21 a.m.: 140° F
• 12:07 p.m.: 134° F
• 12:38 p.m.: 130° F
• 1:07 p.m.: 126° F
• 1:41 p.m.: 124° F (this was after leaving the cap open for the past half hour)

After 5 hours, the coffee had lost 54° F from brew temperature. Honestly, if you haven’t had your coffee 5 hours after brewing, you’ll probably never drink it. At 124° F, it was still coffee I would drink. I’m super impressed with this product! This is especially great if you are going on a road trip or have a long commute to work. You can also get a slightly larger version of the Rambler that holds 30 oz. but has a smaller bottom so that will still fit into any cup holder.

Conclusion

The Yeti Rambler is a great option for a to-go mug! It keeps it warm for a long period of time, and is super durable. If you are shopping around for one of these, I would also recommend looking at The Carter Everywhere Mug that I wrote about here.
