...that caffeine is very water soluble and so, if you want to have a cup of tea at bedtime, the best way is to pour a little boiling water on teabag, wait a second then remove teabag. Then throw that tea away. Start again to make a cup of tea using the same teabag, which will have lost most of its caffeine? And there you have -decaffeinated tea.
I make a large pot of Assam . When it's right remove tea bags and it's perfect for at least four cups/ mugs even. If I use leaf then I have to strain into a fresh pot which is a faff.
I like tea fairly strong but when I first went to DH's house his DM used to make tea that coated the sides of the cup. Strong Builders' Tea wasn't a strong enough description of it
But what if everyone doesn't want the same strength? I like my tea very weak so, if I'm with people who prefer it stronger, I have the first cup and then they let it brew a bit longer.
I, like my grandmother before me, always, when pouring tea from a teapot (usually when in a caf) pour half cups all round first. Then everyone's cuppa ends up the same strength. #perfection
Talking about sharing teabags, when DH was working for a certain company, various offices had their own tea group. One of them was organised in the following way: they used one teabag per session and person A would have the teabag for one minute, person B had the same teabag afterwards for two minutes and then person C would have the teabag for as long as they liked. Then next teabreak they changed roles!
That's all very well jingle, but the tea will be horrible. DH sometimes has an economy drive and insists that we use one teabag for two cups. It's dreadful if you have the second cup. As you might have guessed, I have navvies tea!
