The mug keeps 10 ounces of coffee at whatever temperature you want, for as long as you want.
Over the last couple of weeks, the Ember Ceramic Mug has changed all of this. I usually fail, and end up tossing (or begrudgingly chugging) about a third of my mug's contents when I head back for a refill. Then begins a careful countdown: I have to wait a few minutes for the joe to cool, then drink it as fast as possible before it gets cold.
I fill it to the brim with the delicious Stumptown brews WIRED provides and bring it back to my desk. My daily coffee routine goes something like this: I arrive at the office, drop my bag next to my desk, grab my mug, and head to the kitchen.
