REAL LIFE: ‘We had to make very tough choices’

Have your say

A UNIVERSITY of Portsmouth researcher has claimed the size of the coffee grain is the most important factor in creating a perfect cup of coffee.

Dr William Lee said a better understanding of the physics and chemistry of coffee brewing could lead to better-designed coffee machines.

He said: ‘What makes the best coffee is hideously complicated – from the shape of the filter, to the scale of a single grain, to the flow rate of water and which machine or tool is used, there are an enormous number of variables.’
