I am in Paris this week, and I visited one of the most wonderful and storied tea stores in the city and the world - Mariage Freres. Since 1854, this tea house has been delighting customers with unique flavors and combinations. They were early to the blue tea train too. They told me that they introduced their first blue tea about 6 years ago.
This is their Cactus Bleu that is for gorgeous blue iced tea.
