iced American and cold extraction have different tastes. The former has a stronger and bitter taste, and the smoky taste will be heavier, while the latter has a heavier fruity and sour taste and a smooth entrance.

The making time and temperature of iced American coffee and cold-extracted coffee are different. The former takes only a few minutes. Like hot coffee, coffee is first extracted with hot water at 91-96℃ and then cooled by adding ice cubes. The latter is made with water at room temperature or lower temperature, and the water temperature is usually 2-22℃. Because of the lower temperature, the making process will be longer, taking 12-48 hours.

The caffeine content of iced American coffee is different from that of cold-extracted coffee. The caffeine content of iced American coffee is much higher than that of American coffee because of the high proportion of gouache.

The taste difference between iced American coffee and cold-extracted coffee is that a good iced American coffee can completely retain the original taste of coffee, while cold-extracted coffee itself can fully reflect the subtle taste characteristics of coffee, and the acidity of coffee is milder because of the lower water temperature.

Most of the coffee we drink in our daily life is instant coffee, and coffee made from coffee beans is only used in some regular coffee shops, so if we want to drink good coffee, we still need to go to a store specializing in coffee making.
