Coffee is too hot to safely drink when brewed at the typical brewing temperature, which is about 195˚F/90˚C. It must cool to around 155˚F/68˚C to drink without burning us. Vacuum insulated travel mugs work extremely well, which means our coffee stays way too hot all the way to work if we keep the lid in place.

If we remove the lid on our way to work, we often spill it on our clothes, which nobody likes. On our desks, with the lid removed, the coffee cools. We check email, do a short meeting. We drink a few sips. We do a few other tasks, come back, and the other 60% of our coffee is cold. Nobody likes that either.

We can’t put the steel mug in the microwave (well, only once) so we find another cup, transfer, etc. Once again, nobody likes that. We have solved all these problems with our patented device, the CoffeeThrottle™.

Our device lowers our coffee temperature to comfortable drinking temperature in 2 minutes so we can enjoy it right away. Later, as our coffee cools, the CoffeeThrottle™ restores the recovered heat back into our coffee, making it warmer longer. It’s an insert to our regular coffee mugs that works immediately with most top brands of cups with no modifications, and we can easily move it from cup to cup once it comes out of the dishwasher.
