Tea drinkers across the country have been asked to reveal their desired colour - the first indicator of strength. And one particular hue has won comprehensively.
What do you think of this?
Hotel chain Premier Inn is behind the survey. The company polled 1,000 Brits from around the UK to put the graph together.
Tea colour prompts debate. I know one northerner who recently posted a photo of a weak cuppa next to a strong one. She claimed the light, milky option was the favoured choice of southerners.
And then there are biscuits. What's the perfect accompaniment? A Rich Tea comes out top when dunked.
But what about Digestives? Hobnobs?? It's all a bit of a mess, frankly. McVitie's even told us recently that Chocolate Digestives are actually upside-down. Really?
Oh. Yes. And then there's the long-running and ridiculous argument about whether milk should be poured in first.
To settle the trivial milk disagreement, Fortnum & Mason has a handy explainer...
"Putting the milk in last was considered to be the 'correct' thing to do in refined social circles. In the early days of tea-drinking, poor-quality cups were inclined to crack when hot tea was poured into them, and putting the milk in first helped to prevent this.
"When finer and stronger materials came into use, this was no longer necessary – so putting the milk in last became a way of showing that one had the finest china on one's table. It became a 'social-divider', and not about taste.
"Having said that, there is a good reason for adding the milk last – it's easier to judge the correct amount of milk to add once you have seen the strength and colour of the tea.
"On the other hand, putting the milk in first means that the fat in the milk emulsifies in a different way when the tea is poured, which does change the flavour of the tea, giving it a more even, creamier flavour.
"It also cools the tea slightly to a more acceptable drinking temperature."
Ultimately, Fortnum & Mason says drink tea however you like.
