To prepare ice coffee from the best coffee it depends on what kind of coffe you purchase because there are various brewing methods, with the fundamental division being cold brew– brewing the coffee cold, yielding different flavor, but not requiring cooling – or brewing hot and then cooling, generally by simply pouring over ice or into ice cold milk. In case of hot brewing this can be normally brewed coffee (drip, press pot), or espresso. In case of hot brewing, sweeteners and flavorings are often mixed into the hot coffee before cooling, due to higher solubility in hot water. Alternatively, syrup (sugar pre-dissolved in water) may be used. Pre-packaged iced coffee is available as a grocery item in several countries. Regardless of brewing method, iced coffee is generally brewed at a higher strength than normal coffee, due to the dilution caused by the ice. Iced coffee is a cold variant of coffee. The iced latte and iced mocha are examples.
But for instance in India ice coffee usually consists of instant coffee mixed with cold/frozen milk in a blender, producing a thin, coffee-flavored smoothie or often mixed with vanilla for icy thick experience. South Australians, especially in Adelaide, are also known for this. A more upscale version is popular in the espresso bar chains Barrista and Cafe Coffee Day. This is made with a shot of espresso and cold milk, similar to a latte.
Vietnamese iced coffee, also known as Ca phe da or cafe da (literally “ice coffee”) is totally varies from the abow mentioned ones. Because- at its simplest, –Ca phe da is made with coarsely ground Vietnamese-grown dark roast coffee individually brewed with a small metal French drip filter into a cup containing about a quarter to a half as much sweetened condensed milk, stirred and poured over ice. The coarse grind allows the use of the cà phê phin.
Ingredients for four glasses: 8 teaspoons of coffee powder/isntant coffee, 600 ml water, sweetened condenced milk
Methods: Prepare coffee. Fill the half of the glasses with shaved ice or ice cubes. Pour over ice the hot coffee and add 2-to 4 sweetened condenced milk. Stir it well with a coctail stick. It may be served already chilled, or poured hot over ice. Because sugar does not dissolve readily into cold liquids, it must be added either directly to the hot base, or to the finished product in the form of syrup.
