Unlike many of the other Serious Eats reviews I’ve done, this review lent itself well to a control group: a mug of coffee simply left on the counter. The Ember Travel Mug² uses seven temperature sensors, a rapid cooling system, a microprocessor-controlled heating system, and temperature presets to easily dial in your perfect temperature.

The mug will only keep liquid warm between 120-145°F, so if you want something hotter or cooler, this mug can’t do it. There’s no uniform understanding of the relationship between temperature and flavor (our article notes, for example, that “beer turns bitter when warmed from its typical serving temperature; coffee, on the other hand, has been found to taste less bitter when cooled down from piping-hot. I’d argue you need a good gooseneck kettle to make a great pourover, or a decent machine to make great espresso at home, but you absolutely do not need a temperature control mug to enjoy coffee. The sleek mug is available in a range of colors, and we found it comfortable to drink from (though the lid does become hot and condensation can drip from it as you lift and replace it).Although it’s supposed to maintain a temperature of 130 degrees, it only did so for around 15 minutes before cooling down. Based on the results from the SmrtMugg Pro — it was the top performer in our tests but is currently unavailable — we feel confident recommending this SmrtMugg model.

Although the mug held up in performance, I did notice that the digital interface was starting to wear (when I set it to heat at 135°F, half of the “5” would no longer flash). Ohom's Ui Mug earns its place on your desk or counter by offering multifunctionality: Not only did it keep coffee warm for 90 minutes when the lid was in place during our testing, the Qi warming plate can also be used to charge your cell phone and even some wireless earbuds. It's easy to use — simply push the large button on the bottom — then pair it with the Ember appto set your temperature preference, which defaults to a drinkable 135˚F.

In cases where DPD is not possible (Scottish Highlands), we will send via Royal Mail Tracked 24, as DPD do not offer a Next Day Service to these areas. as it continued to "cook," but we found that for shorter periods, heated mugs did keep coffee hot and that warmer coffee was more palatable than cooler coffee.
