Freeze-dried instant coffee is a soluble coffee made from brewed coffee extract. Ground coffee needs a brewing step to extract the drink; instant granules have already been extracted and dried, so they can be dissolved in water.
The
National Coffee Association’s instant-coffee guide explains the distinction. Freeze drying describes a production method. It does not by itself establish the coffee’s blend, roast, ingredients, caffeine level or taste.
For an MR.VIET range, identify the exact product in the
coffee catalogue and check its specification. A plain soluble coffee and a ready-to-drink mix containing sugar, creamer or flavourings are different formulations, even when both are prepared by adding water.
