Heat retention curve, EM77, ABS
Stelton get many questions in regards to how long our jugs/mugs keep the coffee/tea warm. Our engineers have measured how long boiling water keeps warm after pouring into our assortment of vacuum jugs and mugs.
Please, see the result to the left. The temperature is shown vertical and the hours horizontal. The red hatch area shows the recommended serving temperature. The curve shows that the coffee when served in the vacuum jug still can be served after more than 5 hours. Whether the coffee still tastes fresh or a new jug should be brewed is up to you.
