Temperature plays a huge role in the taste of your morning coffee or afternoon tea. Believe it or not, the ideal drinking temperature for coffee or tea is at 135° Fahrenheit and it’s nowhere near the average serving temperature of 160° F. So, most people are left with a scalding hot or lukewarm cup of coffee. California-based Ember Technologies wants to fix the hot beverage epidemic that’s haunting coffee and tea drinkers worldwide – so they created the Ember Mug.


“I started Ember because I was inspired to change the way people experience eating and drinking,” said founder and CEO Clayton Alexander.

Intelligent Design Features

The Ember Mug allows users to select their ideal drinking temperature anywhere between 120° to 145° then it maintains itself for up to two hours (on the go) and all day long on Ember’s charging coaster. With a company-wide mission focused on “making eating and drinking more gratifying through temperature control,” Ember Technologies engineered the only adjustable mug that keeps your coffee at the preferred temperature.


The leak-proof, highly portable Mug allows users to customize their coffee or tea temperature by either connecting to the Ember app or via a rotational dial located at the base of the Thermo mug. In other words, Ember can be used as a connected device or on its own. Giving the user total control over the Ember’s temperature will maintain brew and steep levels in both your coffee and tea. With an optional ceramic Halo Lid ($29.95), you can enhance the aroma of your coffee and tea while maintaining the perfect temperature throughout the day. Burnt tongues give way to the perfect cup of coffee.

The Ember Mug Technology

As the leader in temperature control technology, Ember Technologies developed its own patented phase-change cooling system. If you pour a scorching hot cup of tea from a boiling kettle, Ember’s built-in technology can rapidly reduce the temperature of your beverage by simply rotating the dial at the bottom of the mug or by pressing a button in the smartphone app.

The Ember App

The Ember Mug comes equipped with an iOS/Android compatible smart app that gives you full control over temperature. Whether you want to remotely adjust the temperature of your morning coffee, name your Mug, select from pre-saved hot beverage temps, or switch between Celsius and Fahrenheit, the choice is entirely yours. The Ember app empowers the user to fully customize the drinking experience. Once the user selects their ideal temperature, the Ember app will send a notification to their smartphone letting them know that their favorite beverage is ready to drink.

Bottom Line

Aside from the price ($149.95) being a rather aggressive, this innovative device maintains perfect coffee temperature throughout the day. There is certainly a niche market for Ember, and as Starbucks prices continue to rise, you may want to maintain the taste of your $5.00 Grande Latte a bit longer after purchase.
