Twitter has marked the fifth annual National Tea Day in Britain with a debate on the perfect cup of brew.

Kicked off by Delish, the catering company posted a selection of 16 teas of different shades to their Twitter account , asking followers 'which colour is right'.

The thread started a lively debate on the best method to make the perfect cuppa, and many slammed the fourth row - calling the paler shades of tea an 'abomination'.

Meanwhile others argued that milk should always be added after the tea has brewed, explaining that the fat content in the milk 'stops the milk from brewing properly'.

Taking to Twitter today, Delish wrote: 'It's National Tea Day! But it raises lots of questions including - what colour is right (see the scale below) and milk before or after the hot water? 

'How ever you make yours, take time to have a cuppa and have a lovely day'.

And shade '2D' proved to be one of the most popular, the exact middle shade from the selection.

One user wrote: 'D2 is optimal. The bag and the milk should never touch', while another added: '2D but milk first before water'.

Disagreeing, another said: '2D, Yorkshire Gold; milk first - controversially', and another tweeted controversially: 'Always milk first and the water has to be a rolling boil'.

'D2 and B3 and I always put the milk in last. Yorkshire Gold to see me through today. Hope you enjoy yours today too'.

Winning another vote, a user wrote: 'D2, the only one that's not too dark, weak nor skimmed.'

Addressing the lockdown another wrote: 'Depends on milk deficit and rationing in your fridge and in household.. As you only are allowed to buy 1pk '.

And slamming the lightest coloured row 4, one wrote: 'It's tea flavoured milk!'.

Others shared their more complex tea making skills, with a tea lover writing: 'At work, depends if teapot (bag or leaves) or teabag in mug to brew. Most like me brew with a tea bag (or 2) in mug with boiled water, leave 2 - 4 mins depending, then after spooning out bag pour milk (3 types) to desired colour (but a few put teabag & milk in then water'.

Another said: 'D2. Bag first, squeeze bag with spoon against the cup to extract all the flavour add milk whilst swirling with a tea spoon. No sugar.'

And naming a common pet hate of tea making, one tweeted: 'I'd also add put used tea bag straight in the bin don't let it sit on a spoon by the sink some people even have trays for used teabags? Why? The bin is right there and is only a tad more effort'.
