Coffee encyclopedia coffee beans begin with the liberation of bitterness

As I said last time, the real taste of coffee is not bitter. But most people still think coffee tastes bitter. Let's find out why.

The first and most important thing is that coffee has freshness. Coffee freshness is the same as tofu, seafood, and fresh milk. Coffee, rich and rich in flavor, begins to deteriorate at a rapid rate once it comes into contact with air. We don't buy tofu that is one month past its production date because its taste has changed and it is not good for our health. Coffee that exceeds the production period of one month is the same reason. Although it does not harm health, it has lost its original pure aroma and taste after roasting for one month.

And even coffee that is not too long past its roasting time but uses bad ingredients will not taste good. Coffee gets a new life through a process called roasting, where it meets fire. Coffee reveals its aroma and flavor through a series of thermochemical reactions. Long-aged or poor-quality green coffee beans will never taste good. Just as there is a difference in taste between old and new rice, old coffee beans and fresh coffee beans are similar in appearance but different in flavor when roasted.

Finally, a word about instant coffee, which is known worldwide. The raw material used to make instant coffee is not ground coffee beans, but prepared coffee drinks that are rapidly compressed and frozen. This is diluted with water and processed with various seasonings or milk preparations for daily drinking. The sweet ingredients in this seasoning can become bitter if they are too concentrated in a rapidly compressed state. This is a coffee making method, right? Of course, the taste made in this way cannot be different from the taste of coffee made with good materials and technology, and it is very different.
