I was recently invited to take part in the Thermos Overnight Coffee Challenge. Arriving at Prufrock Coffee in Central London where we were first taught all the hints and tips to be a top Barista (read Mr R's account coming soon).
When the event finished we were given a large Thermos flask (1.2L vacuum insulated beverage flask) with coffee brewed at mid-day and challenged not to open it until the following morning and to report whether the coffee was still hot. It should be because the flask keeps liquids hot for approx 24 hours.
As difficult as it was, I resisted the urge to see if the liquid was still hot! The following morning we tried the coffee. It was warm but not hot. I was disappointed but I had an inkling as to why it was not. The amount of coffee in the flask was only about half capacity.
Many thanks to Thermos for the 1.2L flask and for the 470ml insulated travel tumbler we got to take home. I know these will keep us supplied with hot drinks on the allotment for years to come!
