We're tea drinkers and I only make tea in a tea pot. I hate it when someone gives me a tea bag in a cup of hot water or makes a cup in the microwave, it always tastes bitter. Forget about ordering tea in a restaurant unless it is a tea shop.
I have tea pots of all sizes, individual, 3 cups for just DH and I and big pots for when family and/or friends are here. I boil fresh water in a big tea kettle, DH says the water must be boiling merrily. I never reheat the tea left in the pot after it gets cold, something DH does in the microwave.
As an aside, I've also found that my regular brand of coffee, Folgers Decaf, has lost its taste, doesn't taste like coffee at all. Cleaned coffee maker with vinegar and no difference in the taste. Just bought Maxwell House Decaf and hope it's better tasting or I won't be able to begin my days at all. May in Jersey
