I'm from 'The North' in Britain and I was raised to drink tea that would be bitter as hell if it didn't have at least a small amount of sugar and a light dash of milk in it. It's the sort of stuff that 'puts hairs on your chest' and gets me through a hard day's work, much like it did for my forebears.
I also like posh black tea on its own and I personally frown upon people who put loads of milk in the stuff, yet apparently quite a few tens of millions of people in India have it just so.
Crazy, huh?
//obviously, I realize that people around the world have different tastes :P Where I am from literally no one drinks tea with milk, but adding a slice of lemon is extremely popular(I can guarantee that if you order tea at a restaurant it will be served with a slice of lemon to the side), but in the UK it's the opposite - people look at you like you are some kind of demon for adding lemon to tea.
In point of fact, cheap Lidl coffee is actually weirdly really really good.
That's just my crazy taste buds though. The closest explanation for this is being a "supertaster"[1]. I've done the supertaster blue-dye tongue test but compared to my friends we saw no noticeable difference.
I understand it for coffee but tea isn't even bitter. That's just insane.
