I make ice tea year around. It's mostly what I drink. I heat a gallon of water in the microwave for 10 minutes. I use a gallon tupperware pitcher. Put the sugar in, then pour the hot water over it, stir & add the tea bags. I use Celestial Seasonings herbal tea. I let the bags in & toss them when my tea is all gone. My tea is never cloudy or has a bad taste the next day or after.
