Today I want to talk to you about one of my favorite caffeine free tisanes (infusions not from the camellia sinensis plant). In the afternoon and evening, I usually switch from caffeinated beverages to caffeine-free ones. There is as much variety in the herbal tea realm as in the camellia sinensis world and I love discovering new flavor profiles. Soba cha, also known as roasted buckwheat tea, comes from a type of buckwheat that is related to the one that is commonly used in the kitchen.
