Secret to the perfect cuppa finally revealed
A new guide to making the perfect cup of tea may finally settle the question of when to add the milk in a breakthrough that will be a blow to many purists.
The British Standards Institution (BSI) has released a guide called Preparation Of A Liquor Of Tea For Use In Sensory Tests that sets out what it deems to be the essentials for a perfect brew.
According to the BSI, the milk must be poured into the cup before the tea, which should be brewed for six minutes.
The standard could finally end the debate around whether milk should be added to the cup before or after the tea.
But the BSI has gone further still, determining that a pot made of porcelain is an essential, and there must be at least two grams of tea to every 100ml of water.
The temperature cannot go beyond 85C (185F) when served but should be above 60C (140F) for "optimum flavour and sensation".
As the average tea bag contains 1.5g of tea leaves, at least two tea bags should be used for a small pot, and four for a large one.
