Is hanging-ear coffee pure coffee powder which is the better difference between hanging-ear coffee and instant coffee?

Hanging-ear coffee is pure coffee powder without adding other additives. The production process of hanging-ear coffee is to grind the coffee beans into coffee powder, then put the coffee powder into a hanging-ear coffee bag, seal it, and make it by packaging. What's the difference between hanging-ear coffee and instant coffee? Instant coffee can not be regarded as pure coffee powder, because most instant coffee has the addition of granulated sugar and plant fat powder. The production process of instant coffee is very different from the coffee we drink in coffee shops. Instant coffee is first roasting a large number of raw coffee beans into ripe coffee beans, then crushing them into coffee powder and extracting them with industrial boilers to get espresso. Then quickly freeze and preserve the flavor, grind the frozen espresso liquid and dehydrate it in vacuum to get the instant coffee powder. Finally, add seasoning and package to the instant coffee we usually drink. So which one of them is better? Personally, I recommend hanging-ear coffee, the quality of hanging-ear coffee beans will be better than instant coffee beans, and there is no added sugar, plant fat powder these. It tastes healthier, too.
