Roasted coffee beans

If you’re a coffee lover, you may get more impressed by knowing about the roasting process of coffee beans. Originally, coffee beans are small ruby red berries that go through so many different actions to become a tasteful cup of coffee that we always enjoy.

Firstly, the raw coffee seeds are dried to remove the outer skin and pulp. The dried raw coffee seeds are the ones that we know as green coffee beans. We can consume these beans as green coffee, or pass them to the roasting process. The roasting process requires great care and science, and the coffee beans are tasted several times during roasting. Because there’re specific moments in which beans start to crack, and release sugar, so if coffee experts don’t pay enough attention during making roasted coffee beans, they’ll ruin a large number of beans that are harvested and proceed with a lot of care and are exported from very unique regions.

Roasting Coffee

Unroasted coffee beans, known as green beans, contain the same amount of caffeine, and acidity level. However, the unique aroma and flavor of coffee are locked inside beans, so in order to get the fresh taste and smell of coffee beans, they need to get into the roasting stage.

Roasting coffee is a process that leads to both chemical and physical changes in coffee beans. Coffee experts put raw coffee beans exposed to very high temperatures, then put them into the cooling process very quickly by using special equipment. Roasting coffee beans completely changes the weight and appearance of beans and brings out a special flavor from coffee beans. You should know that you can keep unroasted beans as long as you wish, but once the beans are roasted, they may diminish and lose their flavor and smell after a while.

After you figure out all the information needed about the type of coffee beans you like, you should learn about the function of roasting too. Roasting contains step-by-step actions that are explained below:

  1. Drying: After being harvested, raw beans usually contain some water, so in order to get rid of the moisture, beans need to be dried.
  2. Turning from yellow to light brown: once beans lose all the moisture and water, they start changing color to light brown because of the chemical changes.
  3. Steam: when heating beans, steam will also rise from beans meaning the water inside coffee beans is evaporating.
  4. Cracking: after a while, the sugar inside beans starts to caramelize and you hear a cracking sound which means that the beans have expanded and they’re lightly roasted. Then, if you hear a second crack, it indicates the medium roast level. So, the more you wait, the more your beans get roasted.
  5. Cooldown: when the heating process ends, beans should be moved to another colander to cool down.
  6. De-gassing: finally, the beans should be allowed to de-gas for about a day in a container. After that, the roasted coffee beans will be ready for brewing.

As you can understand, there’s a great combination of science and art in making roasted coffee beans, and not everyone can make a rich coffee.
