Arabica Coffee Bean: Source of Elegant Flavors

Origin and History

Coffea Arabica, the world's most consumed coffee type, was first discovered in the high altitude regions of Ethiopia. According to legend, in the 9th century, an Ethiopian shepherd noticed that his goats behaved more energetically after eating the fruits of the coffee tree, and thus the stimulating effect of coffee was discovered. Over time, this plant moved to Yemen and spread there through Arab traders. It takes its name from here, the Arabian Peninsula. Today, Arabica accounts for approximately 60-70% of the world's coffee production.

Growing Conditions and Production Regions

Arabica coffee is generally grown in mountainous regions with an altitude of 600 to 2000 meters. High altitude causes the bean to mature more slowly, which adds more complexity to the flavor profile. This type of coffee is more sensitive to diseases and environmental changes than Robusta; Therefore, it is more laborious and costly to grow.

Arabica coffee is produced primarily in Brazil and Colombia; It is produced extensively in countries such as Ethiopia, Guatemala, Kenya, Honduras, Costa Rica. Each region gives coffee its own unique aroma layers with its climate and soil structure.

Taste Profile: Fine, Aromatic and Balanced

Arabica coffee is known for its soft and balanced taste. It generally has floral, fruity and sweet aromas. Light fruit flavors such as lemon, apple, strawberry; It can combine with sweet notes such as caramel, honey or chocolate. Its body is generally light or medium density. Additionally, it contains less caffeine (1.2–1.5%) compared to Robusta, which supports its smooth drinking.

Thanks to this aromatic structure, Arabica is a favorite of qualified coffee producers and third generation coffee shops. Each coffee bean offers a different experience depending on the farm where it grows, the climate and the processing method.

Which Types of Coffee Are Used?

Arabica beans stand out with brewing methods such as filter coffee, V60, Chemex, Aeropress, Cold Brew and French Press. These methods allow the delicate and layered aromas of the bean to be felt more clearly. It is also preferred in making espresso; It is used alone or blended with Robusta.

Excelsa Coffee Bean: A Rare and Layered Flavor

Origin and Classification

Excelsa coffee bean was first discovered in Africa in 1904 and was classified as a separate species for a while. However, today, it is considered a subspecies of the Liberica species (Coffea Liberica var. dewevrei) due to its genetic structure. Despite this, its taste profile is quite different from Liberica and it has a special place thanks to its unique aromas.

Excelsa is generally grown in small quantities in Southeast Asian countries, especially in places such as Vietnam, Philippines and India. Its share in global coffee production is quite low; For this reason, it is mostly preferred by small producers or boutique coffee shops.

Growing Conditions and Production Areas

Excelsa coffee grows on very high and broad-leaved trees. It likes warm and humid climates and is generally grown at mid-altitudes. It is more resistant than other species, but its yield is low. This makes it rare and valuable.

Taste Profile: Fruity, Slightly Sour and Complex

Excelsa coffee attracts attention with its complex and multi-layered taste profile. Its aroma contains both fruity lightness and deep, roasted notes. Especially sour-fruity flavors followed by roasted chocolate or woody tones give this coffee a unique character.

The flavor profile can sometimes be as lively and sharp as a white wine. For this reason, while it can be drunk alone, it is often used when blended with Arabica to add depth and liveliness to mixtures. The acidity rate is moderate; The taste that remains on the palate is long-lasting.

Uses and Brewing Methods

Excelsa coffee is mostly found in special coffee blends. It offers an unusual drinking experience when used alone, and with this feature it appeals especially to experienced palates looking for a difference in coffee. Its aromatic structure can be highlighted with brewing methods such as V60, Aeropress and Cold Brew.

In recent years, thanks to the third generation coffee movement, boutique roasters and private cafes have started to use Excelsa more frequently. Thanks to its rarity and characteristic taste, it has managed to enter the radar of coffee collectors and gourmets.

Liberica Coffee Bean: An Exotic and Rare Taste

History and Origin

Liberica coffee was first discovered in West Africa, especially in Liberia, in the mid-19th century. It was discovered in the region. Its name was named "Liberica", inspired by this region. Due to the coffee rust disease that affected the Arabica species in the 1890s, it was brought to Southeast Asia by producers looking for alternatives and became widespread there. Since then, it has been grown especially in countries such as Philippines, Malaysia and Indonesia.

Growing Conditions and Production Areas

Liberica has larger trees than Arabica and Robusta and can grow up to 20 meters. For this reason, the harvesting process is quite laborious. Their nuclei are also much larger and characteristically asymmetrical, almond-shaped. Liberica bean likes hot and humid climates; It generally grows at low and medium altitudes.

Although it constitutes a very small part of world coffee production today, it has an important place in local markets and special production. Particularly in the Philippines, Barako coffee is a local example of the Liberica species.

Flavor Profile: Strong, Woody and Exotic

Liberica coffee is quite different from other beans in taste. The flavor profile is often characterized by woody, smoky, sometimes even floral and fruity notes. It attracts attention with its full-bodied and aromatic structure. While for some palates this taste may be described as "strange" and far from the usual coffee flavors, for others it is a unique and impressive experience.

At the same time, it has a balance of low acidity and distinct bitterness. Thanks to its aromatic intensity, it leaves a lasting impression on memories. The exotic character of this bean is very attractive to those looking for a difference in coffee.

Uses and Brewing Methods

Liberica coffee is generally consumed locally with filter coffee or brewing methods. Due to its intense aroma, it can be added to some coffee mixtures in small amounts to create a different depth. Especially third generation coffee roasters aim to offer unusual tastes to coffee lovers by using this species in their special series coffees.

Robusta Coffee Bean: Representative of Strong Flavors

A Species Known for Its Durability

Robusta coffee bean, scientifically known as Coffea Canephora, is more durable than Arabica. stands out with its structure. This type of seed, first discovered in West Africa in the late 19th century, is highly resistant to diseases and hot climate conditions. Therefore, from the perspective of producers, it is easier to grow and less costly than Arabica.

Where is it grown?

Robusta beans are generally grown in regions with tropical climates at altitudes of 200 to 800 meters. Today, the largest Robusta producer is Vietnam. In addition to Vietnam, Brazil, Indonesia, India and Uganda are also among the important Robusta producing countries. Thanks to the efficient production in these countries, Robusta accounts for approximately 30-40% of the world coffee market.

Taste Profile: Hard, Intense and Stimulating

The taste of Robusta is quite different from Arabica. It is harder, denser and distinctly bitter. It is generally characterized by earthy, woody and sometimes nutty aromas. It is low in acidity, which means a flatter flavor profile. However, its most striking feature is its high caffeine content. While Arabica beans contain an average of 1.2-1.5% caffeine, this rate can be up to 2.2-2.7% in Robusta. With this feature, it is an ideal choice for those who have difficulty waking up in the morning or those looking for a strong stimulating effect.

Where is it used?

Robusta coffee is frequently used, especially in espresso mixtures. The main reason for this is the intense taste that Robusta adds to espresso and the thick crema layer it creates. It is also widely preferred in the production of instant (soluble) coffee and Turkish coffee. Although it may be too intense for some palates when drunk alone, very delicious results can be achieved by balancing it with Arabica in blended coffees.

The world of coffee beans offers a richness far beyond that hot liquid poured into our cup. From the elegant aromas of Arabica to the strong and bold taste of Robusta; From the exotic character of Liberica to the surprising flavors of Excelsa, each bean takes our coffee experience to a different dimension.
