If you're a coffee enthusiast, you may have noticed that the taste of coffee can vary from one place to another, even when using the same type of coffee beans.

The secret behind this lies in the selection of coffee beans by each vendor.

But what makes these small coffee beans capable of creating such diverse flavors? Before we delve into this question, let's first grasp the basics of coffee beans.

Coffee beans are the seeds of plants belonging to the Coffea genus. They grow in regions between 30 degrees south latitude and 25 degrees north latitude, and their flavors vary depending on the climate and region where they're cultivated. Workers harvest, roast, and grind these beans, turning them into the delicious coffee that many of us enjoy.

Freshly ground coffee beans contain the most original and undamaged flavors and layers. This is why coffee brewed with freshly ground beans tends to have a superior taste and aroma compared to using pre-ground coffee. If you've ever felt like the coffee sold in cafes lacks a certain flavor, it's likely because they're using pre-ground coffee instead of freshly ground beans.

While commercially available coffee powder is convenient, it's prone to moisture and deterioration, which can compromise the freshness and original flavor of the coffee. For those seeking the most flavorful and full-bodied coffee, opting for freshly ground beans from a grinder is undoubtedly the best choice.

Since coffee beans are the essence of a delicious cup of coffee, and different types of beans create different flavors, how can we distinguish between them? What exactly is Arabica coffee, a term we often hear? And what about Blue Mountain Coffee? Let's explore various types of coffee beans to gain a better understanding.

Though there are hundreds of coffee varieties worldwide, Arabica and Robusta beans are the two most commonly cultivated types. Arabica beans dominate the market share, accounting for 75-80%, while Robusta beans make up about 20%. Here's a closer look at each:

Arabica Coffee Beans: These beans are less resistant to pests and diseases and thrive in highland areas. They have lower caffeine content but higher fat and sugar content compared to Robusta beans. Arabica beans offer a sweet and sour taste reminiscent of plums and fruits, making them highly prized for their flavor and aroma. They are typically more expensive than Robusta beans and are often used to brew specialty coffees or single-origin brews.

Robusta Coffee Beans: Robusta beans are highly resistant to pests and diseases and can adapt to various soil conditions. They grow quickly and yield a large coffee output, making them more cost-effective than Arabica beans. Robusta beans have higher caffeine content and lower sugar content, resulting in a more bitter and robust flavor profile. They are commonly used to produce instant coffee and canned coffee.
