My family is from Kentucky. Thank you. You are so right. Sugar added to the tea then put in the sun can brew bad stuff. Set it on your counter to cool down just a bit about 5. Min. . Then put in fridge. I do add sugar after it is cold. . But. I have started boiling water or using well water. If boiling, let it cool down. Then add tea and put in sun. Thank you Anne for your insight
