Today is wife’s birthday. I gave her a Fellow travel mug, the Carter. She likes it. I tested it.

I took some pictures for the gallery and then compared it to my Yeti. The yeti is 18oz whereas the Carter is 16oz. Both have screw top lids.

I filled them both with coffee that measured 80.7C, and screwed on lids, then filled up a 6oz cup. Left all on counter, ambient temperature was 22.1C

While at work, the first chance that wife gets to drink coffee is after three hours from leaving home. I opened everything up at the three hour mark and measured the temperatures. I am pleased to say the Carter outperformed my Rambler, but also sad to say that.

The temperature of the coffee in the Carter was 69.3C and the Rambler was 68.4C. To be honest, I could not distinguish the difference between the temps after burning my tongue on the first tasting, haha. I can really only start drinking coffee when it hits about the 60C mark. For reference, the cup on the counter had cooled to room temperature, which was 22.4C at this point. It was soothing.

The Carter has a wide mouth and a thin lip. I found the thin lip made drinking very comfortable. The wide mouth meant that I could enjoy the aroma of the coffee to the max. Enjoying the aroma was important at this point, because I was not tasting much at this point.

My wife likes her coffee scalding hot. When I prep her cup in the morning I will heat her milk while preheating her cup with black coffee. After sitting for a bit, I then dump it into mine. This heats her cup significantly, and lowers the temp of my coffee a bit, which means I can get to it sooner.

The Carter came in a little black bag, that the top folds back on. I think this baggy can be used to carry the cup around, as well as provide a little bit more thermal protection for the coffee goodness within.

I will run a couple more temperature drop tests. With the bag, with preheated cup, then with bag and preheat the cup. I am curious to see what the differences will be.
