THE TIME-HONOURED APPROACH
TO THE PERFECT CUPPA
Apparently making the perfect mug of tea is all down to the science. University researchers last year devised a mathematical formula for the ideal brew. The optimum brewing time is two minutes and the ideal amount of milk is 10ml. The
perfect drinking temperature of 60c is achieved six minutes later – but
after 17 minutes and 30 seconds the tea will be past its best as it
falls below 45c. Or, as
the scientists at the University of Northumbria put it in their
formula:
TB + (H2O at 100 degrees centigrade) 2mins BT + C (10ml) 6mins BT = PC (at OT 60 degrees centigrade).
TB means tea bag, BT is brewing time, C is milk, PC means perfect cuppa, and OT stands for optimum temperature.
For the research, commissioned by a milk company, the team spent 180 hours in the lab testing brewing methods, and a panel of volunteers consumed 285 cups of tea.
