I‘ve been tea total for almost 18 months. Before that I was a whisky fan (the good stuff, Scotch single malt), and missed the many flavors. I found out you can blend your own teas and whereas it won‘t get you drunk you can at least have some kind of tasting experience.
I mostly dabble with herbal and fruit teas, best fresh from a pot (rosemary, thyme), fresh ginger, lemon, orange or tangerine peels, or dried stuff like bamboo leafs, lemongrass, orange blossom. Good open leaf moroccan mint is very nice. You can also use vanilla, cinnamon, whatever you want. As sweetener, rasp some licorice.
