I'm a iced tea junkie!lol Some of my "GOURMET" iced teas are called "ICE TEA" because is how we said it, in south central pennsylvania in the 70s.lol If you buy a sample of iced tea,it would make one quart. (half w/tea and half with cold water or ice) A 3oz bag make a lot of iced tea, depending how strong you would like it. Mix -shake the bag everytime you make TEA. Some of my iced tea blends are light and some are stronger then others. If it is an herbal iced tea, you can steep it much longer to get a stronger flavor. For a half-gallon: I use two level tablespoons. Also depends what you like. You can cold brew over night or use hot water. Enjoy my "GOURMET" Ice Tea Creations.
