I've just ordered another 9 boxes of Ahmad Ceylon tea bags from Amazon, so that's my favourite at the moment. Amazon kindly upgraded my free delivery to next day courier delivery but the courier delivered them to the wrong address. I got them this morning from the householder.
I tried Luaka Organic Ceylon bags recently and didn't like them at all.
I think Jacksons Fairtrade Kenyan tea bags are delicious, but there's no way I'm paying full price for them from Twinings. Three months ago I finished the last of 20 boxes I had that cost me 39p a box from B&M.
Sadly B&M haven't had any decent tea in for ages. Before they opened up we had a 'Nice Price' chain store locally (they went bust about 5 years ago) and I was able to buy Tetleys Organic Orange Pekoe bags in small cardboard containers that had been imported from Canada.
I actually emailed and phoned Tetleys to ask them why the bags weren't sold in England and they said (reading between the lines) that we weren't discerning enough, so they had no plans to sell them here.
It was exactly the same story with Tetleys loose Orange Pekoe, also imported from Canada.
I avoid all the cheap tea bags and there's nothing I hate more than being given cheap weak tea when visiting, apart from instant coffee that is. Still, there's no escape from being given horrible beverages, so I just keep quiet, smile, and say it's delicious!
