Coffee beans are known as one of the most popular drinks in the world, but not everyone knows how to distinguish coffee between two main types of beans: Arabica and Robusta. While they are both sources of our favorite coffee, they offer different experiences in terms of taste, shape, size, and price.
Before we dive into each, let’s explore why the distinction between Arabica and Robusta is important not only for consumers but also for coffee producers across the globe.
Understanding the characteristics of each type of bean will help you choose the coffee that best suits your taste and needs. Let’s find out about the characteristics, flavor, size, caffeine content, differences, and how to choose between Arabica and Robusta!
Distinguish coffee: Characteristics of Arabica coffee beans
Arabica coffee beans, with the scientific name Coffea Arabica, are the most popular coffee, accounting for about 60-70% of global coffee production. The main distinguishing feature of Arabica beans is their oval shape, usually 6-8mm long, which is different from the smaller size of Robusta beans. When it is green, Arabica beans are light green or turquoise, and after roasting, they turn bright brown, creating an attractive and even appearance.
Arabica beans also have a mild, sweet taste, often bringing a mild sour taste and a sweet aftertaste after enjoyment. Many people love Arabica because its caffeine content is between 1.2-1.5%, which is lower than that of Robusta beans, which makes it feel lighter to enjoy. This lightness is also the reason that Arabica is often preferred in high-end cafes and in espresso products.
Flavor and color
The taste of Arabica coffee beans is one of the main reasons why it stands out in the market. With a blend of mild sweetness and sourness, Arabica creates a sophisticated coffee experience. A cup of Arabica coffee usually feels comfortable and pleasant, like a soothing afternoon over a hot cup of coffee. Many people also mention that fruits such as cherries, oranges, or strawberries can be evident in the taste of Arabica coffee.
- Color: Arabica beans are turquoise before roasting and turn bright brown when done. This creates a layer of oil that covers the surface of the grain, which represents its premium quality.
- Time tolerance: Arabica beans are often criticized for being more perishable than Robusta due to their higher natural sugars and moisture content, making them susceptible to oxidation and loss of their precious flavor.

Distinguish coffee: Characteristics of Robusta coffee beans
Robusta coffee beans, with the scientific name Coffea Canephora, are also one of the two main types of coffee. Robusta’s distinctive features include its high durability and good resistance to pests and more extreme climatic conditions. Robusta beans are typically smaller than Arabica, having a round shape and a light green color before roasting.
Robusta beans are often consumed more in instant coffee and espresso thanks to the rich taste and thrill it offers. This has led to the popularity of Robusta in some cafes and many cheaper coffee products.
Distinguishing Arabica and Robusta Coffee: Taste and Color
The flavor of Robusta coffee beans is often described as bold and has a strong bitterness, with a hint of earthy and fleshy aroma. This is in contrast to the mild sweetness of Arabica. In terms of color, Robusta beans before roasting are usually bright green and when roasted, they turn dark brown but are usually less shiny than Arabica.
- Richness: The bitterness of Robusta is not only overwhelming, but it also creates a strong feeling, giving the feeling that someone is “urging” you to start your day.
- Intended Use: Due to its strong taste and ability to foam crema, Robusta is often dominant in espressos, helping to create a thicker and richer foam.

Distinguishing Arabica and Robusta coffee beans
Once we understand each type of coffee bean, we can delve into the more detailed distinction between Arabica and Robusta. It’s not simply the difference between taste or size, but also the factor of price, market, and expectations from consumers. In today’s global context, there are constant debates about which coffee to choose to serve your needs.
Differences in taste
Taste is the biggest determinant in distinguishing between Arabica and Robusta. Arabica beans usually bring light, pleasant notes with fresh fruity notes, while Robusta beans stand out with a strong bitterness, like a rolling wave. When enjoying a cup of coffee, one can immediately feel this difference.
- The blending method also affects the flavor: Arabica beans can be extracted better in gentle brewing methods, while Robusta works better in more aggressive methods such as espresso.
- Consistency in flavor between different coffee products is also an important factor. Arabica beans generally offer more stability in terms of flavor, while Robusta can vary quite a bit depending on environmental factors.
