I’m British, so black tea with milk (or substitute) and some kind of sweetener to taste is what most of us (and most of Ireland too) go for.

As for which black tea, we don’t really consider that unless we’re at least a couple of levels into serious tea drinking. Most supermarkets sell own-brand and name brand tea bags that we gladly grab every time we’re in a supermarket, but what’s in them is generally a blend made for taste more than anything else.

I am not sure how tea purchasing works in other countries. Sometimes what we drink is called “breakfast tea” or “builder’s tea”, if that helps.
