I've been finding a lot of information lately on chemicals in tea. This video was published in August 2014. It will be interesting to see what strides have been made with regard to the quality and purity of these brands.
I grew up drinking Red Rose tea in Canada. For many years now the brands of tea bags that I buy have varied from Salada to Tetley and also many brands of loose teas.
I was happy to hear that Red Rose was the only tea mentioned in this video that is pesticide free. Until I have done more research on the subject, I'll be switching back to Red Rose tea. A nice perk is the little Wade figurines included in some boxes.
Some of the figurine series have become quite collectible.
The last box of Red Rose tea I purchased had this Wade figurine from the American Heritage Series called Tea Crates.
