Why does freshly ground coffee taste better than instant coffee?

Why freshly ground coffee tastes so much better than instant coffee? what's the difference?

After looking at the above steps, I found that coffee is not so difficult to grind. A cup of coffee made from coffee beans is really much more mellow and tastier than fancy coffee and instant coffee. Finally, remember to carefully clean the coffee-making utensils with hot water after brewing coffee, and then put them into clean water. Do not put the filter cloth in a dry place, you must first prepare coffee drinking utensils, everything is the first thing, we should prepare coffee bean grinder, these two are used to grind coffee beans later, and then there is a siphon pot, which is the main tool for making coffee later. If you want to grind a good coffee, the stirring spoon is also indispensable. Then we can grind the beans. The first step is to put the coffee beans into the bean grinder and put in two tablespoons. Then clean up our most important coffee machine siphon pot with boiling water, and then put the water into the pot, remembering that you have to heat it over high heat, and when the hot water in the pot is no longer bubbling, we can put the coffee powder into the pot and stir it with a coffee spoon to make sure the coffee powder is free. When all this is done, we will wait quietly until it has been boiled for a minute, gently shake the siphon pot left and right, and then turn off the fire. Finally, pour the coffee into the cup, and finally put a bag of milk or sugar, and a cup of full-bodied coffee will be freshly baked!

First, the grinding leaves out all kinds of additives and cream, as well as wood fiber, pectin, carbohydrates and so on. You are responsible for your health.

Second, freshly roasted beans, plus your own practice, you will get a feast of coffee with thousands of fragrances, and then you will drink the floral aroma of coffee. Which one would you choose compared to flavor additives?

By the way, why do you have to have decaf? Arabica's own caffeine is relatively low, you said you go to drink low-caffeinated beans, have you really drunk that taste? Are you sure you can drink all kinds of astringent and bitter tastes? So far, the real low-caine and delicious coffee beans don't seem to have been found. Going back to the coffee itself, is it really good to have low caffeine? Just like you buy a sour green apple to eat, what you enjoy is the sour taste of the apple. Suddenly, one day, you buy a green apple without sour taste. Don't you feel strange?
