Sorry but I can't help (always stock up on Twinings when I'm back in the UK).
Don't tell anyone else but I go to Wilkinsons and buy Typhoo One Cup and it's fine, I prefer it to Twinings. I know, I just do..!
The tea is only one component in a good brew.
I don't like Yorkshire Tea, over-rated. Perhaps it's the water thing.
Bleugh! Don't tell me you put UHT milk in tea. I stopped putting any dairy products in my cup decades ago, and now, when I'm back in blighty, I take my tea as nature intended there, too. Once you go black, you never go back. Or something like that.
Fresh milk only, full fat brings out the flavour of the tea.
I like Tetley here :(
Polska Tetley? Not for me thanks.
That's not tea, it's milky water! You might as well not bother with the tea bag at all!
I used to work with someone who drank tea like that, they also loved trashy take away sandwiches.
