Thero

Just-Right Coffee

As a grad student, Thero vacuum-insulated mug Maker Chloris Yang was frustrated with burning her mouth on too-hot coffee and then, inevitably, ending up with too-cold coffee after letting it cool off for too long. Chloris put her book-smarts to use to create a solution that prevents both of those unsavory scenarios. Thero cools scalding hot coffee down to an ideal 140 degrees Fahrenheit in under two minutes and keeps it there for up to five hours. Science is doing the temperature-controlling work here, thanks to phase change material (also known as PCM) sealed inside double-walled stainless steel. It quickly absorbs heat from the coffee and slowly releases it back to maintain that magical temperature. Chloris put thought into the design of the lid, too, and made it spill- and leak-proof, and easy to use with one hand. So every sip can be a perfect one.
