4 Types of Coffee Beans: How to Choose
Updated - Team Colipse
Types of coffee beans refer to the various species of coffee that come from the coffee plants. There are four different types of coffee beans: Arabica, Robusta, Liberica, and Excelsa, with Arabica and Robusta being two of the most popular types.
Besides species, types of coffee beans are further categorized by their varieties, cultivars, origins, quality, processing method, farming practices, and roast level. Different types of coffee beans come in various sizes, are grown in various countries under different conditions, and are used for different types of coffee drinks.
Regarding the number of coffee bean types, experts at World Coffee Research identify more than 120 coffee varietals—genetically distinct variations within a single species. These varietals, or varieties, refer to naturally occurring variations of coffee. Cultivars, on the other hand, are coffee varieties that have been specifically bred or selected by humans for certain traits, like disease resistance or flavor profile.
The choice of coffee bean type and roast level, combined with the brewing method, significantly impacts the final flavor. This can make choosing the best type of coffee beans and grounds for different coffee drinks a bit complex. The following list shows 4 different types of coffee beans and their characteristics.
The four main types of coffee beans are listed below.
- Arabica
- Robusta
- Liberica
- Excelsa
1. Arabica Coffee Beans
Arabica coffee beans are the seeds of the Coffea arabica plant. Arabica coffee beans originated in South Ethiopia's forests and spread globally by the mid-1700s. Arabica coffee beans are the most popular type of beans in the world. In 2023, Arabica beans made up over 60% of the global coffee supply, with a projected 2024 production of 99.8 million 60-kilogram bags per the USDA’s Foreign Agriculture Service. Brazil supplies nearly 40% of the world's Arabica coffee. Other major Arabica coffee producers include Colombia, Ethiopia, and Honduras.
The two most common types of Arabica coffee varietals are Typica and Bourbon, while rarer types include Geisha (Gesha), Blue Mountain, and Pink Bourbon. The best Arabica coffee beans are those that suit individual preferences for flavor, aroma, and acidity. Many brewing methods are suited for Arabica coffee beans, but they go exceptionally well in drip coffee, single-serve coffee, cold brewing, and espresso.
Arabica coffee is known for its natural sweetness, fruity flavors like berries, apples, tropical fruits, and subtle floral notes of jasmine, hibiscus. It often has higher acidity, described as bright, tangy, or wine-like. Roasting can impart nutty, caramel, or chocolate undertones. However, compared to Robusta, Arabica has a lighter body and a clean, lingering aftertaste.
This table summarizes the key characteristics of Arabica coffee beans.
| Characteristic | Description of Arabica Coffee Beans |

Light to medium roasts best preserve Arabica's natural flavors. Colipse sells Arabica coffee beans that are perfect for a variety of coffee drinks. We recommend the medium roast Arabica Blend.
2. Robusta Coffee Beans
Robusta coffee beans are the seeds of the Coffea canephora plant, native to Central and Western Africa. Robusta coffee grows well at altitudes below 600 meters and is highly resistant to pests and diseases, making it resilient in various climates. This coffee bean is widely cultivated in equatorial East Africa and Southeast Asia, with Vietnam, Brazil, and Indonesia as leading producers.
The two most common types of Robusta coffee beans include Erecta and Nganda. The two most rare types of Robusta coffee beans include Congensis found in Central Africa and Laurentii. The best types of Robusta coffee beans are those that provide a strong, full-bodied flavor with a minimal bitterness and a smooth finish. Espresso, French press, Cold Brew, and Moka pot are among top brewing methods that work well with Robusta.
Robusta coffee is known for its strong, earthy flavor profile, often described as bold and bitter with notes of dark chocolate, nuts, and a slight graininess. Its body is fuller and more intense than Arabica, with a heavier, lingering aftertaste. While Robusta has lower acidity than Arabica, its higher caffeine content creates a robust, pronounced flavor. This strength makes it ideal in espresso blends, enhancing crema and providing a substantial mouthfeel.
The following table shows the key characteristics of Robusta coffee beans.

What are Coffee Bean Types?
Coffee bean types are the seeds of the coffee plant (Coffea), found inside coffee cherries that ripen from green to red/purple and are harvested at peak ripeness for optimal quality. Each cherry usually holds two flat beans. Occasionally, a single round “peaberry” is found. After processing, these become green coffee beans made of carbohydrates, lipids, proteins, and caffeine. The two main types of coffee beans are Arabica (larger beans) and Robusta. Arabica has a smoother, more nuanced flavor with hints of sweetness, fruit, and chocolate. Robusta has a bolder, more bitter taste. Arabica is preferred for quality-focused coffee production.
What are the Different Types of Coffee Beans?
The four different types of coffee beans are Arabica, Robusta, Liberica, and Excelsa. Arabica beans dominate global production due to their smooth, aromatic flavor with chocolate and caramel notes. Robusta beans, the second most popular, offer a bolder, more bitter taste with a higher caffeine content, often used in espresso blends. Liberica beans, from West Africa and Malaysia, have a fruity flavor with a smoky aroma, while Excelsa beans, reclassified as part of the Liberica family, offer a tart, dark flavor with notes of fruit and spice. Each coffee bean type possesses distinct characteristics that influence the final cup, from its origin and processing method to its roast level and brewing technique.
What are the Best Types of Coffee Beans?
The best types of coffee beans are Arabica. They have smooth, complex flavors with notes of fruit, sugar, and berries, as well as lower acidity and caffeine compared to Robusta. Arabica coffee is the most popular type in the specialty coffee market, making up 60-70% of global production. The beans can be brewed in many different ways, like espresso and pour-over, and it shows the unique flavors of where it's grown and how it's processed.
What Type of Coffee Beans Should I Buy?
You should buy coffee beans based on your preference for flavor, roast level, and brewing method. Arabica beans offer a smooth, mild taste, while Robusta beans provide a stronger, more bitter flavor. Choose whole beans for freshness and a roast level that matches your brewing style, such as light for acidity or dark for boldness. The best place to buy coffee beans online is from specialty coffee stores, like Colipse Coffee, which offers two kinds of coffee beans, Arabica and Robusta, freshly roasted to order.
What are the Different Types of Coffee Beans Varieties?
Different types of Arabica coffee bean varieties include Bourbon, Typica, and Geisha, while Robusta varieties include Erecta and Nganda. Coffee varieties are genetic groups within coffee species, each with unique characteristics shaped by origin (e.g., Ethiopia or Colombia), farming practices, growing region, altitude, bean size, and disease resistance like leaf rust. Different coffee bean varieties have distinct cupping profiles, with significant variations in aroma, flavor, acidity, and body. Nutritional values, including caffeine and mineral content, can also differ.
Some coffee bean varieties, like Caturra, SL34, and Pacamara, result from natural mutations, while others, such as Castillo, Catimor, and Ruiru 11, are hybrids from intentional breeding between different coffee plants. Cultivars are selected coffee varieties maintained through cultivation for traits like disease resistance, high yield, or unique flavor. In the strictest sense, a coffee "cultivar" is a plant variety that has been produced through cultivation and is maintained through farmer-assisted propagation. All coffee cultivars are varieties, but not all coffee varieties are cultivars.
How do Coffee Bean Types Differ Based on Roasting?
Coffee bean types differ based on roasting through the development of varying flavor profiles, acidity levels, body characteristics, and aroma complexities. Coffee roasting is the process of heating green coffee beans to unlock and enhance these inherent qualities.
The main types of coffee bean roasts—Light, Medium, Medium-Dark, and Dark—offer distinct flavors and caffeine levels. Light roasts retain more caffeine and acidity, creating a mild flavor. Medium roasts balance acidity and sweetness. Medium-Dark roasts add caramelized richness, while Dark roasts provide bold, smoky flavors with reduced acidity. This roasting spectrum creates varied taste experiences in coffee bean selection.
How To Choose Coffee Bean Types According to Brewing Method?
To choose coffee bean types based on your brewing method, consider the method's unique traits.
- For espresso, which uses high pressure and a short extraction time, use a dark roast with a fine grind for a strong, concentrated flavor.
- For French press and cold brewing, where the coffee steeps for longer, use a medium-to-coarse grind with medium or dark roasts to avoid over-extraction and bitterness.
- For drip coffee, a medium roast with a medium grind provides a balanced flavor extraction for this popular method.
Single-origin beans from high altitude regions like Ethiopia or Kenya are a great choice for pour-over methods like Chemex or Hario V60 as they allow the nuances of the bean to shine. Specialty coffee blends can be a good option for everyday brewing methods like drip coffee, providing a consistent taste. Single origin coffee beans and blends are among the many types of coffee beans offered by Colipse.
