Can coffee beans be brewed and drunk directly?

Direct brewing of coffee beans

Coffee is a popular drink, and coffee beans are the main ingredient for making coffee. However, many people are confused about whether it is okay to brew coffee directly from beans. In this article, we will explore this issue and give some relevant advice.

1. Coffee beans and ground coffee

First, we need to clearly distinguish between coffee beans and coffee that has been ground into powder form. Coffee that has been ground into powder form is often referred to as "ready-made" or "instant" coffee. This type of product can be brewed directly without any additional processing.

However, raw coffee beans that have not been processed and ground into powder form cannot be used directly for brewing and drinking.

2. What exists in the raw, unprocessed state?

In the raw, unprocessed process, each coffee bean, with its rich and varied individual flavor and aroma characteristics, is covered by a shell called the "carper." The carper is the protective layer of the coffee bean that envelops it and preserves its freshness.

In addition, there is a layer of substance called "bran film" under the peel. The bran film is a sticky substance connecting the flesh and the core.

Finally, beneath the bran is the actual coffee bean kernel, which is what we usually call "green" or "green beans." These raw coffee beans that have not been processed and ground into powder form need to be processed to make delicious coffee.

3. What treatments are required during the raw process?

In order to remove unnecessary substances produced during the original processing and make coffee easier to brew and drink, we need to perform the following steps:

a. Remove the peel:

First, we need to peel each intact coffee orange from the original unprocessed process and remove the peel wrapped in it. This process is usually called "hulling".

b. Remove bran film:

Next, we need to remove the bran film under the peel. This process is usually called "washing beans" or "fermentation". By soaking and rolling the coffee beans, the bran film can be loosened and easily removed.

c. Baking:

Finally, we need to roast the processed coffee beans. Roasting is a key step that can give coffee beans a specific aroma and taste, and change their color and shape.

4. How to brew coffee beans that have been processed in the original unprocessed process?

Once you have completed the above processing steps, you can use the processed coffee beans to brew delicious coffee. Here are some common brewing methods:

a. Drip brewing method:

Drip brewing is one of the simplest and most popular brewing methods. All you have to do is put the ground coffee beans in a paper filter and slowly brew it with boiling water.

b. French Press:

The French Press is a traditional brewing method that produces a strong, rich-tasting coffee. Simply add ground coffee beans and the right amount of boiling water to the French Press, wait a few minutes, and then press the plunger.

c. Espresso:

Espresso is a very strong and full-bodied drink. You can make this type of coffee using a specially designed espresso machine.

in conclusion

In summary, the raw coffee beans that have not been processed and ground into powder cannot be used directly for brewing. Instead, we need to peel, de-shell and roast them to make delicious, fragrant and rich coffee. Once these processing steps are completed, you can use the processed coffee beans to brew your favorite coffee.
