Especially chai B)
And rooibos. and peppermint.
But my most favorite of all is Celestial Seasons (don't judge me!!!) Bengal Spice, because the roast chicory is a million times tastier than black tea, but has no caff.
But it's really hard for me to pick a favorite. I also freakin LOVE CS Candy Cane Lane.
And Good Earth Sweet and Spicy (protip: add Jager Spice, that's what they drink in Heaven)
in fact, I don't think I've ever had a proper tea I didn't love.
