DON'T squeeze tea bags when you remove them from your cup or you will squeeze tannins into your tea making it bitter. Use filtered water to avoid minerals in tap water which can make tea cloudy or bitter. To prevent food odors from being absorbed, COVER cooled tea being used for iced tea when storing it in the refrigerator . Freeze some tea into ice cubes and use as ice so your tea will not become diluted from using regular water ice cubes.
