What is Arabica Coffee?

Arabica coffee, scientifically named Coffea arabica, is the most popular coffee species, accounting for approximately 70% of global coffee production. The Coffea arabica plant, known for its delicate nature and disease susceptibility, requires specific cultivating conditions. 

These beans, often called "the gold standard," have a superior taste and aroma compared to Robusta. They feature fruit notes, floral undertones, and mild acidity, making them a top choice among consumers worldwide.

Where is Arabica Coffee Grown?

Arabica coffee thrives in high-altitude regions with mild temperatures, abundant rainfall, and ample shade. Each coffee belt region imparts distinct characteristics to the beans due to its specific climate and soil conditions. 

Major Arabica coffee-growing regions include:

  • Kenya: Renowned for its bright acidity, full-bodied flavor, and wine-like characteristics.
  • Ethiopia: The birthplace of coffee, Ethiopia produces a variety of unique, flavorful Arabica beans.
  • Brazil: The largest producer of Arabica coffee, known for its diverse flavors.
  • Colombia: Famous for its rich, well-balanced coffee with a smooth finish.

Growing Conditions

  • Altitude: Arabica coffee thrives at higher altitudes, typically 2,000 to 6,000 feet above sea level. The higher altitude and cooler climate slow the growth of the coffee plant, allowing more time for the beans to develop complex flavors.
  • Climate: It prefers cooler temperatures ranging from 60-70°F (15-24°C) and requires a lot of rainfall, around 60-100 inches (1,500-2,500 mm) annually.
  • Shade: Arabica coffee plants generally prefer shade-grown conditions, which can protect them from direct sunlight and help maintain soil moisture.

Plant Characteristics

  1. Physical Appearance: Coffea arabica plants have dark green, glossy, elliptical leaves with pointed tips; small, white, fragrant flowers that grow in clusters and resemble jasmine; cherries that are initially green, turning red or purple when ripe and usually containing two seeds (coffee beans) with branches growing in a horizontal pattern, forming a dense, bushy appearance.
  2. Sensitivity: Arabica plants are more sensitive to pests, diseases, and harsh weather conditions than Robusta. They are particularly susceptible to coffee leaf rust and coffee berry disease.
  3. Yield: The plants yield less than Robusta but produce higher-quality beans.
  4. Growth: Arabica coffee plants can grow up to 8-12 meters tall if left unpruned, though they are usually pruned to around 2- 3 meters to facilitate harvesting.

How is Coffee Arabica Cultivated?

Cultivating coffee, particularly Coffea arabica, involves several key steps. It starts with selecting high-quality Arabica seeds or seedlings. These seeds are planted in well-draining soil and kept adequately moist during the initial growth stages. Once the seedlings reach a few inches in height, they are replanted directly into the ground. Regular pruning is essential to maintain plant health and prevent diseases.

Roasting coffee beans

Coffee cherries are ready for harvesting when they ripen to a bright red. During this stage, the beans inside the cherries are extracted, processed, and dried. This process varies but typically involves washing, natural drying, or fermentation to prepare the coffee beans for roasting. 

Each step, from seed selection to harvesting, requires careful management to ensure the quality and flavor of the final coffee product.

Coffea Arabica List and Their Varieties

Arabica coffee beans come in various types, each with unique characteristics influenced by their growing conditions, processing methods, and genetic variations. 

There are numerous varieties of Coffea arabica, each offering distinct flavors and characteristics. Some popular varieties include:

SL28

This variety is known for its excellent cup quality, characterized by bright acidity and bold flavors that often include fruity and wine-like notes. It is also prized for its drought resistance, making it suitable for the varying climatic conditions in Kenya.

SL34

Similar to SL28, SL34 is highly regarded for its cup quality, with bright acidity and a balanced flavor profile that can exhibit citrus and berry notes. It is notable for its resistance to diseases, particularly coffee berry disease (CBD), prevalent in many coffee-growing regions.

Gesha

Originally from Ethiopia but popularized in Panama, Gesha (or Geisha) is renowned for its exotic and complex flavor profile. It often features floral aromas reminiscent of jasmine and delicate notes of tropical fruits like mango and papaya. Gesha coffee typically exhibits a silky, tea-like body with a bright acidity that enhances its elegance and refinement. It is highly sought after and commands premium prices due to its rarity and exceptional cup quality.

Ruiru 11

Noted for its disease resistance and high yield, Ruiru 11 is highly resistant to coffee berry disease (CBD) and coffee leaf rust (CLR), making it a robust choice for farmers. The beans are generally smaller and more uniform than other Arabica varieties.

Batian

Developed in Kenya, Batian stands out for its high productivity and resilience to coffee diseases such as berry disease and leaf rust. It combines good cup quality with robust agronomic traits, making it a preferred choice for sustainable coffee farming in regions prone to these diseases.

Blue Mountain

Renowned for its smooth, mild flavor with no bitterness, rich aroma, and medium body. It is considered one of the best coffees in the world for its unique taste and exceptional quality.
