How Costa Rica Grows and Processes Specialty Coffee

When you taste a bright, clean cup of Costa Rican coffee, you’re experiencing more than just good farming — you’re tasting the results of strict national policies, ideal volcanic soils, and a climate fine-tuned by elevation. But what exactly makes Costa Rica’s coffee so consistent, and how does each step from tree to cup shape the final flavor? Let’s break it down.

Costa Rica grows 100% Arabica coffee, legally banned Robusta in 1989, and also restricts Cartimor varieties. Key cultivars include Caturra and Catuai. Coffee is handpicked between August and April, processed mostly via traditional washed methods, then dried on patios for around seven days or, less preferably, via machine drying in 24 hours. The country has eight defined coffee regions, graded by altitude and bean density, with Tarrazú among the most famous.

Why Costa Rica Only Grows Arabica

Costa Rica produces exclusively Arabica coffee. In a rare move, the government passed national legislation in 1989 to prohibit the cultivation of Robusta. This ban was later extended to limit the planting of lower-quality Cartimor varieties. As a result, commercial coffee production in the country focuses solely on traditional, higher-quality Arabica cultivars.

Common Coffee Varieties in Costa Rica

The most commonly grown coffee varieties in Costa Rica are Caturra and Catuai. These cultivars are favored for their adaptability to the country’s volcanic soils and high-altitude conditions. Other varieties may exist, but the national emphasis on quality and the legislative restrictions have kept the coffee gene pool focused on traditional, high-performing Arabica types.

Harvesting Coffee in Costa Rica

Coffee in Costa Rica is harvested entirely by hand. The harvest season typically runs from August to April, but the exact timing depends on the altitude of the growing area. Higher elevations see later harvests due to slower maturation, while lower areas may begin earlier. Careful selective picking ensures only ripe cherries are collected, which is critical for quality processing.

How Coffee Is Processed in Costa Rica

The dominant method is traditional washed processing. After harvest, coffee cherries are depulped, fermented to remove the mucilage, washed, and then dried. Drying is most often done on patios for around seven days until the moisture content reaches 12%. Once dry, beans are stored as parchment. Some producers use machine drying, which can reduce drying time to 24 hours, but this method is often considered to negatively affect the final cup profile.

Understanding Costa Rica’s Coffee Grade System

Costa Rica grades its coffee based on altitude and bean density. Generally, the higher the altitude, the denser the beans. Higher-density beans, grown in cooler temperatures, develop more slowly and are classified as 'Strictly Hard Bean' (SHB) or 'Hard Bean' (HB), indicating premium quality. Lower-altitude beans are less dense and fall into medium or lower grades. Altitude and density are directly correlated: elevation slows ripening, increasing bean density and complexity.

Costa Rica’s Eight Coffee Regions

Costa Rica’s coffee is divided into eight main producing regions. One of the most renowned is Tarrazú, located southeast of the capital San José. Tarrazú is celebrated for its high-altitude farms and is often called 'Costa Rica’s Bordeaux.' Another important zone is West Valley (Valle Occidental), situated about 12 km north of San José and influenced by the fertile soils of the Irazú volcano. Each region offers unique flavor profiles shaped by climate, soil, and altitude.

Organizations Supporting Coffee in Costa Rica

The National Coffee Institute of Costa Rica, known as iCafé, supports and regulates the country’s coffee industry. This government-backed organization oversees research, quality control, and promotion of Costa Rican coffee both domestically and internationally.

Frequently Asked Questions

Why doesn’t Costa Rica grow Robusta coffee?

Costa Rica banned the cultivation of Robusta coffee in 1989 through national legislation. The law was enacted to protect the country’s reputation for high-quality Arabica production. This ban also extends to restricting less desirable Arabica hybrids such as Cartimor, ensuring the focus remains on premium cultivars like Caturra and Catuai.

What are the main coffee varieties grown in Costa Rica?

The most widely cultivated coffee varieties in Costa Rica are Caturra and Catuai. These Arabica types are chosen for their performance in the country’s volcanic, high-altitude conditions. While other varieties may be present, the national emphasis on quality has limited planting to traditional, high-yielding Arabica cultivars.

How is coffee processed in Costa Rica?

The majority of Costa Rican coffee is processed using the traditional washed method. This involves depulping, fermenting to remove mucilage, washing, and then drying the beans to 12% moisture, usually on patios over about seven days. Some producers use machine drying, which takes only 24 hours but is often thought to compromise flavor quality.

What grading system does Costa Rica use for coffee?

Costa Rica grades coffee based on altitude and bean density. Higher altitudes produce denser, harder beans classified as Strictly Hard Bean (SHB) or Hard Bean (HB). These are considered premium due to slower cherry development in cooler temperatures. Lower-altitude beans are less dense and graded lower accordingly.

Which are the main coffee-growing regions in Costa Rica?

Costa Rica has eight main coffee regions. Tarrazú, southeast of San José, is the most famous and often dubbed 'Costa Rica’s Bordeaux.' West Valley, about 12 km north of the capital and influenced by the Irazú volcano, is another key region. Each area has distinct growing conditions that influence the coffee’s flavor.

Who regulates coffee production in Costa Rica?

The National Coffee Institute of Costa Rica, or iCafé, is the governing body responsible for overseeing coffee production, research, quality standards, and international promotion of Costa Rican coffee.
