Having used a premium brand for ten years and never found others to be suitable, I tried this and was amazed, it lasts longer odour free than the brand I have been using and is a very stable product, my choice from now on.
These were the best tea bags on here but the last pack was noticeably different, much weaker with a lack of flavour, sorry - going back to my old tea bags.
I used to buy the sugar variety of these regularly years ago but had to give them up due to the sugar. These sugar free ones taste just like the old ones but I have to go easy on them due to the sucralose - for obvious reasons!
