St. Dalfour is a French company. That is all I know about them. The box says this contains organic Ceylon tea with the all natural flavor of bergamot. The bags are individually wrapped in foil envelope. I don’t know if the box I tried was mislabeled or if it really is their take on Earl Grey tea. I enjoyed it but it tasted like a cinnamon flavored tea not Earl Grey. Much more subtle than the Bigelow cinnamon tea I drank years ago. Not bad but not what I was expecting.
