This is a simple iced latte recipe made from coffee with no sweeteners. PLEASE use a good quality coffee; I use Starbucks Sumatra. My husband likes to add a bit of flavored coffee syrup to his, but I like mine unsweetened. My hubby was surprised at how good it was unsweetened. He thought it had a sweetener in it. He thinks that as is it tastes just like a Starkbucks Frappuccino. I'm not sure I remember exactly how theirs tastes- but it can't be much better than this. This recipe makes 2 quarts. It never lasts more than a day or two here. We love this drink.
