Exotic pizza chef, Wolfgang Puck, has added his name and brand to single-serving self-heating canned coffee. Puck already has a branded milk-jar shaped coffee drink. The new drink will use calcium oxide (aka quicklime) to heat the coffee/latte as hot as 145 F. No, the CaO will not be in the drink directly although that might be a boon to those with osteoporosis. It will be in a patented recyclable container surrounding the Puck formulated drink. The quicklime will be pressed into a tablet or a “puck.”
The technology, which was known to the Romans, is a patented product from On Tech who will be deploying the technology for hot teas and soups as well as other products.
