For hot tea I like the caffeine free herbal teas and I heat up a cup of water in the microwave for about 1 minute and 30 seconds and then I put a tea bag in the hot water with a spoon to weigh it down and I let it steep for a few minutes. If I want another cup then I do the same thing and I reuse the same tea bag. I don't add anything to it.
For cold tea I like Lipton with lemon but no sugar. I've also been buying some premade tea from Trader Joes. It's green tea made with white tea leaves and it has mint added to it too. It comes in a jug and I just put it in the refrigerator. It sure tastes good.
When I lived in S.C. I always thought that the tea was too sweet. People in the south love very sweet tea but I've always preferred it just plain with lemon.
