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 cup of coffee or a lukewarm cup if your timing is off. That’s no way to start the day. 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.
