Arabica Beans vs. Robusta Beans. What’s the Difference?

Arabica and Robusta are the two most commonly grown types of coffee beans. Arabica beans are known for their higher quality and are usually more expensive than Robusta beans.

Arabica beans are grown at higher elevations, resulting in more nuanced flavors.

Robusta beans, on the other hand, are grown at lower elevations and are more resilient, making them easier to cultivate. They also have a higher caffeine content, so they are often used in blends to add some extra kick.

According to the International Coffee Organization (ICO), Arabica coffee accounted for approximately 60% of global coffee production in 2020, while Robusta coffee accounted for the remaining 40%.

When it comes to consumption, preferences vary by region. In North America and Western Europe, Arabica coffee is generally more popular. However, in Asia and parts of Eastern Europe, Robusta coffee is commonly consumed. Some countries, like Italy, prefer espresso blends that include a significant percentage of Robusta coffee.

It's important to note that coffee consumption trends can be influenced by factors such as culture, demographics, and economic conditions. Therefore, popularity levels for Arabica and Robusta coffee can differ greatly from one region to another.

Major producers of Robusta coffee include Vietnam, which accounts for about 40% of global production, as well as Brazil, Indonesia, India, and Uganda. While Robusta coffee is generally considered to be of lower quality, specialty Robusta coffees from India and Vietnam are gaining recognition for their unique flavors and becoming more popular among coffee enthusiasts.

Acidity Levels

Arabica coffee generally has lower acidity compared to Robusta coffee. Arabica beans provide a smoother, more delicate flavor profile with lower acidity and higher sugar content, resulting in a sweeter and more balanced cup of coffee.


Robusta coffee beans, on the other hand, have a more robust and earthy flavor profile. They tend to be more bitter and acidic. This higher acidity can be desirable in certain types of coffee, such as espresso, as it helps to cut through the milk and create a more distinct flavor. However, the higher acidity of Robusta coffee may be less appealing to those who prefer a milder, less acidic cup of coffee.

What is the difference between light, medium, and dark roast coffee?

Light roast coffee is roasted for a shorter period, resulting in a lighter color and a more acidic and fruity flavor profile. Medium roast coffee is roasted a bit longer, providing a more balanced flavor profile with notes of chocolate and caramel. Dark roast coffee is roasted for the longest period, resulting in a dark color and a bold, smoky flavor profile.

Should I buy whole bean or ground coffee?

For the freshest and most flavorful cup of coffee, it is generally recommended to buy whole bean coffee and grind it yourself. However, pre-ground coffee can be a convenient option for those without a grinder or with time constraints.

How should I store my coffee beans?

To maintain the quality of your coffee beans, store them in an airtight container in a cool, dry place. Avoid storing them in the refrigerator or freezer, as moisture and odors can impact the flavor. It's also crucial to use your coffee beans within a few weeks of roasting for the best flavor.

What factors affect the flavor of coffee beans?

Several factors affect the flavor of coffee beans, including the region and altitude of cultivation, as well as the processing method used.

The Makeup of Coffee

A coffee bean is a seed found inside the fruit of the coffee plant, known as a coffee cherry. The coffee cherry is a small, fleshy fruit that takes about 9 months to ripen. Once ripe, the cherry is harvested, and the coffee beans are extracted through a process called "milling."

Coffee Bean Makeup

The coffee cherry itself is edible and has a sweet, tart flavor. However, it is typically not consumed in its whole form due to its small size and large pit (the coffee bean). Some coffee farmers and enthusiasts experiment with using the fruit of the coffee plant in different ways, such as fermenting or drying it to make a tea-like drink.

Understanding the coffee plant and the fruit it produces allows coffee lovers to appreciate the complexity and diversity of coffee flavors and aromas.

A coffee bean has two main parts: the outer layer called the "cherry" and the inner seed known as the coffee bean. The cherry is a fruit that grows on the coffee plant and is usually red or yellow when ripe. The coffee bean itself is a small, hard seed located inside the cherry.

The coffee bean has different parts, including the outer silverskin, which is a thin layer typically removed during the roasting process. Beneath the silverskin is the parchment layer, a thin, papery covering also removed during roasting.

The main parts of the coffee bean are the endosperm and the embryo. The endosperm is the bulk of the bean, containing most of its flavor compounds and other important characteristics. The embryo is a small, white nub at the base of the bean, housing the genetic material for the coffee plant.

Roasting affects the composition of the coffee bean. During roasting, the bean undergoes chemical reactions that transform its flavor and aroma. Roasting also affects the bean's structure, making it more porous and brittle, which can impact how it behaves during brewing.

Coffee Growing Seasons

Coffee is typically an annual crop, although some countries like Colombia and Sumatra may have two harvests per year. The main harvest season lasts for several months when coffee cherries ripen and can be picked. It's important to note that the harvest timing can vary due to weather conditions and climate changes, leading to uncertainty in the industry's future.

The coffee growing season varies by region. Generally, coffee plants flower in the spring and summer, and the cherries ripen in the fall and winter. Some regions may have two distinct harvest seasons in a year, while others have only one.

In Central and South America, the main coffee harvest season is typically from September to December. In East Africa, the main harvest season is from April to July. Indonesia's harvest season varies by region, with some areas having two harvest seasons per year.

Weather patterns and other factors can influence the timing and quality of the coffee harvest. Excessive rainfall or drought can impact the crop's quality and yield. Coffee farmers must also monitor pests and diseases that can affect their plants.

Understanding the coffee growing season helps coffee lovers make informed choices when purchasing and brewing their favorite coffee.


Coffee is usually harvested by hand, with workers selectively picking only the ripest cherries. This labor-intensive process is known as selective picking. In some cases, machines are used to strip all the cherries from the trees at once, but this method can result in a lower-quality harvest with more unripe or overripe cherries.

After harvesting, the cherries are sorted to remove any debris or damaged cherries. They are then processed to remove the outer layers and reveal the coffee beans inside. The specific processing method depends on the region and desired flavor profile.


Proper storage is essential for maintaining coffee quality. Green coffee beans can be stored for several months to a year, depending on conditions. Ideally, store green coffee in a cool, dry place with consistent temperature and humidity levels.

The length of time coffee can be stored varies based on factors such as coffee type, processing method, and storage conditions. High-quality Arabica coffees may begin losing flavor and aroma within a few months of harvesting, while Robusta coffees can be stored for longer periods.

It is generally recommended to use green coffee beans within six months to a year of harvesting for the best flavor. Roasted coffee should be consumed within a few weeks to a month for optimal freshness. However, coffee can still be consumed beyond this timeframe, although the taste may not be as fresh or flavorful.

Shipping Times

The time it takes for coffee to reach its destination depends on harvest time, export periods, and ocean voyage duration. For example, coffee from El Salvador can be exported to the US in just two weeks, while coffee from Congo or Rwanda may take up to two months to arrive.


Latin American coffees offer good body, acidity, and a hint of fruitiness. They have flavor notes that are often chocolatey, nutty, or with a slight citrus overtone.

  • BRAZIL – Brazil is one of the world's top coffee producers. Its coffees are known for their nutty and sweet characteristics, full body, and suitability for espressos. Some beans from Brazil may have flavor notes of spice or citrus.
  • COLOMBIA – Colombian coffees are well-balanced with a medium body. They offer caramel sweetness and subtle nuttiness. These coffees have moderate acidity that complements their inherent sweetness.
  • GUATEMALA – Guatemalan coffee is rich and flavorful due to its volcanic soil. It has slightly higher acidity and a hint of smokiness, which distinguishes its taste. These unique qualities make Guatemalan coffee popular among coffee lovers.


African coffees are known for their higher acidity and bright flavor notes. They often have fruity, floral, and sweet taste characteristics.

The major growing regions in Africa are Ethiopia and Kenya.

  • ETHIOPIA – Ethiopia is the birthplace of coffee with a wide variety of coffee varietals that are still grown wild. Ethiopian coffees have a fruity, wine-like profile. Dry-processed coffee offers taste notes of blueberry or strawberry with a heavy, syrupy mouthfeel. Wet-processed coffee has delicate floral nuances and a lighter body.
  • KENYA – Kenyan coffee is bold, vibrant, and juicy, making it highly prized and priced. Kenyan AA beans are well-known for their larger size. Kenyan coffees have a savory to sweet taste, with tartness reminiscent of tomatoes or black currants. Overall, they are well-balanced with pleasant nuances that coffee aficionados appreciate.

Regions and Flavor Profiles

The flavor of coffee beans is influenced by the region in which they are grown. Here are some common coffee growing regions and their associated flavor profiles:

Coffee Profiles

What region produces the best coffee?

The notion of the best coffee region is subjective and depends on individual preferences. However, Central and South America, Africa, and Asia are well-known coffee growing regions.

The cupping process

Professional coffee tasters, known as "cuppers," follow rigorous protocols to assess coffees. They use a tasting format that evaluates fragrance, aroma, flavor, aftertaste, acidity, body, uniformity, and defects. This detailed analysis helps inform producers about farming and processing practices, set market value, and determine ideal customer demographics.

As a coffee drinker, understanding the efforts put into developing accurate flavor profiles can empower you. Cuppers and coffee quality graders provide detailed information about coffee tastes. You can also track your preferences through a Brew Log, observing the countries, growing regions, and flavor attributes you gravitate towards.

What is the best type of coffee bean?

The best type of coffee bean is subjective and depends on personal tastes. However, Arabica beans are generally considered to be of higher quality.


Asian coffees are known for their bitter and earthy flavors, often with notes of dark chocolate, earth, and herbs.

Asia is emerging as a promising coffee-growing region. While Vietnam and Indonesia are major coffee exporters, specialty coffee production in Thailand, Malaysia, and Java is also on the rise.

  • INDONESIA – Sumatra coffee offers a bold, dark, and full-bodied experience. It has a distinct smoky, musty, and earthy quality, making it perfect for dark roasts. Some coffees from this region have complex flavors of dark chocolate and herbs that are unique to their growing locations.
  • MALAYSIA – Malaysian coffee is primarily made from Liberica coffee beans, which produce fruity, nutty flavors with a clean aftertaste. Malaysian coffee is known for being very strong in taste as well.
