FrontStreet Coffee - Introduction to Three Major Coffee Varieties

1. Arabica

Arabica coffee plants are usually short, with slightly slender green leaves and small oval fruits; the variety is also known as small-seeded coffee. It offers outstanding flavor, a captivating aroma, and bright fruit acidity. The beans have uneven surfaces and an S-shaped central crease, and Arabica accounts for roughly 65%-70% of the world's coffee trade. It is generally considered the only coffee variety that can be consumed on its own. The character of high-altitude regions comes through especially well. Although it is genetically disadvantaged (a specific chromosome count, monoecious, primarily self-pollinating), which leaves it with weak vitality and poor resistance to pests and disease, its high commercial value keeps it the most widely cultivated variety. The famous Blue Mountain coffee is a genetic mutation of Arabica.

2. Robusta

Strictly speaking, the variety that originates from Coffea canephora is known as Robusta only by nickname; its proper name is Canephora, and it is native to the Congo in central Africa. Compared with Arabica, it has stronger vitality, better resistance to pests and disease, and lower cultivation and management costs. Its beans are uniform in shape. Unfortunately, it falls short in flavor, and its caffeine content is roughly twice that of Arabica beans in the same quantity, so it is not well received by coffee drinkers. Compared with Arabica, Robusta has less noticeable acidity but a prominent bitterness. Its flavor is relatively simple, yet it is rich in oils, which is why Robusta is widely used in instant coffee and canned coffee.

In fact, premium-quality Robusta exists as well. These days some traditional roasters blend a higher proportion of Arabica with a small amount of Robusta for their espresso beans. This slightly lowers the cost of the final blend, increases yield, and adds richer oils, a more distinctive bitterness, and excellent layered complexity.

3. Liberica

Liberica coffee trees are tall evergreens with upward-growing trunks and large fruits. They have strong vitality but relatively poor flavor, aroma, and resistance to pests and disease. Most Liberica is traded in West Africa. With weak commercial value, it is now grown mainly for species preservation or scientific research and is rarely discussed in detail.

The main producing countries include Indonesia, Vietnam, and the West African nations centered on Côte d'Ivoire, Algeria, and Angola. West Africa is the origin of Liberica coffee, and the plant adapts strongly to a wide range of environments, whether hot or cold, humid or dry, with the one exception that it is susceptible to leaf rust disease. Because its flavor is inferior to Arabica, it is traded only domestically in some West African countries (Liberia, Côte d'Ivoire, and others) or cultivated for research purposes.

Key Point

"Arabica" is not synonymous with good coffee. Even among Arabica varieties, there are grade differences.

FrontStreet Coffee Recommendation

Blue Mountain is the classic example of what a mutation of Arabica can become at its best, and strictly speaking only coffee grown in a defined area of Jamaica's Blue Mountains and certified by the Jamaican government may be called Jamaica Blue Mountain Coffee. The Blue Mountain range rises in eastern Jamaica and includes the island's highest peak at 2,256 meters; near-constant mist gives the range its name. High altitude widens the day-night temperature difference and lengthens the fruit's ripening period, fertile volcanic soil supplies nutrients, and steady, even rainfall lets the cherries accumulate sugar and aroma slowly. The result is the delicate texture and balance the coffee is famous for.

FrontStreet Coffee's Blue Mountain No.1 sits at the top of the grade scale and comes from the historic Clifton Estate, where coffee has been planted and processed since roughly 1750. The estate's growing and processing area sits at an average of 4,300 feet (1,310.64 meters), where gentle afternoon cloud, ample sunshine, and mineral-rich soil extend the cherries' maturation. Traditional Blue Mountain is shipped in wooden barrels of 15, 45, and 70 kilograms, and each barrel is itself a mark of the genuine article. Roasted medium-dark to emphasize body and that classic bittersweet balance, the cup is very clean, complex, and gentle, with chocolate sweetness and a lasting fruit finish. FrontStreet recommends a Kono dripper, 15 grams of coffee for one serving, a rest of 4-7 days counted from the roast date, a grind slightly coarser than for a light roast - about the texture of granulated sugar - water at 87-88°C, and a 1:15 ratio, poured in three stages: 30 grams of water for a 30-second bloom, then up to 120 grams, then up to 225 grams.
