My recipe to make a gallon is 6 black tea bags, 4 green tea bags. Supposed to steep in a pot of boiling water for 5-10 minutes. Sometimes I forget and go an hour or two.
Sometimes I dump a little tube of lemonade mix in. My tastes are very unrefined.
I found cold-brewing was so much easier and tastes the same. I put ten tea bags in a gallon of water overnight in the refrigerator. Three to four tea bags in large throat water bottle works well too.
Ok well I do my homemade green drinks. My backyard grows rosemary, parsley and Swiss chard. Add in lemon or lime and a little protein powder in the blender plus water and a dash of turmeric Phytonutrients baby - good for the health and brain. I really do like the taste of Coke but the unhealthy sugary fizz plus leftist Wokeness is one more reason for my green liquid concoction only.
The important thing is finding something you like.
