You may not think insulated bottles, what you probably think of as a Thermos, would be lust-worthy tech, but damn I love my Zojirushi. By putting a partial vacuum between my perfectly-brewed 205F coffee from the outside world, my Zojirushi will keep my coffee hot for a long time. A very long time. The upshot is that I can make an awesome Kone of coffee at 8AM and finish it at three or four hours later, without losing precious temperature or breaking those complex organic molecules that make it taste soooo good by reheating the brew.
However, the best thing about the Zojirushi 17-oz Thermal Mug isn’t its insulating prowess, but the lid. In place of a spout and a tiny mug, Zojirushi uses a button-activated flip-top lid with a basin perfect for sipping extremely hot coffee, without scalding your tongue. And for those rare times you don’t want instant access to a near-boiling beverage, you can activate the safety catch with no fear of accidental leakage.
