If you want to avoid caffeine, go herbal or rooibos. A little bit of caffeine is in green and white teas, and (I’ve read) also decaf black teas.
Black teas (lots of caffeine) are my preference, and it’s up to whether or not you want a flavor. English Breakfast is a good basic black tea. Earl Grey will always have bergamot and that’s a distinctive flavor.
Then, depending on the brand, flavors can be added like nut (chestnut, almond, etc) or butterscotch or berries.
For black tea, you’ll also see labels like Ceylon, Assam, Darjeeling - I’m not enough of a connoisseur to differentiate between those; I just buy what I like the taste of.
Also, if you are eating while drinking tea, the tea can affect how you perceive the flavors. I like dark chocolate (Ghirardelli 86%). Some black teas make the chocolate taste amazing. Some black teas make the chocolate taste drier than baking chocolate. It’s a bit of trial and error.
Good luck! 🫖 #tea #teastr
