Coffee plants

There are at least 17 different known species of coffee plants, but commercial production of coffee is mainly limited to the Coffea Arabica (Arabica coffee) and Coffea Canephora (Robusta coffee) plants. In smaller amounts there is some production of two more species that are closely related: Coffee Excelsa, that is mostly found in northern Africa and Coffea Liberica, found in both western Africa and the Philippines.

For all species of coffee plants variations exists, so-called varietals. Some of those varietals are natural, but some have been made by crossing varietals in order to improve for instance harvest or resistance against diseases. Below is a far from complete listing of different varietals per coffee species.

Arabica

Arabica plants are considered to give the best tasting beans from the main coffee species. The plants were discovered by Europeans in the Middle-East (hence the name Arabica). Arabica plants have very specific demands on their environment, which makes them more difficult to cultivate. The plants require soils rich on minerals (for instance volcanic soils) at at least 500m altitude, a moderate temperature around 20 degrees centigrade and sufficient rainfall.

Tipica

Tipica is considered one of the oldes varieties of the coffee plant. The tipica plant is tall, up to 4m. The plant has a low production but the beans are of excellent quality.

Bourbon

Bourbon coffee plants are the descendants of the coffee plants the French planted on Bourbon Island (nowadays known as Reunion). In the late 19th century the Bourbon coffee plant was exported and planted in Brazil from where it spread over latin-america. Bourbon plants have a 20-30% higher production than Tipica plants but with equally good quality beans. Bourbon plants grow best at high altitudes, between 1200 and 2000 m.

Harar

Harar is one of the oldes coffee beans still in production and can be found almost exclusively in Ethiopia. Harar coffee has a typical mocha flavour, but due to very simple harvesting techniques Harar coffee varies a lot in quality.

Caturra

Caturra is a mutation of the Bourbon plant that was discovered in Brazil in ... The Caturra plant has a high production and good quality, but has the downside that it needs a very rich soil and more care. Caturra plants can grow on slightly lower altitudes than Bourbon plants; between 500 and 1800m.

Mundo Novo

A natural hybrid between Tipica and Bourbon created in the 1940s. Called after the town of Mundo Novo in Brazil.

Maragogype

A variety of Tipica discovered in Brazil. The plant is taller than the Tipica plant and has a low production. The exceptionally large beans give a coffee with a very particular taste.

Catuaí

A man-made hybrid between Caturra and Mundo Novo made in Brazil in the 1940s. It is a short strong plant that is favourite in areas with harsher climates.

Blue Mountain

Coffee was brought to the Jamaican Blue Mountain area from other Carabean islands by the English. It has turned into a whole new variety of high-quality coffee plants that produce excellent coffee.

Catucaí

Yellow and Red Catucaí originates from Brazil, the names referring to the distinct colours of the berries. Some Catucai is also grown in Asia, for instance in southern India.

Pache

There are two variations of the Pache plant, Pache comun and Pache colis. They are variations of the Tipica plant and were first discovered in Guatamala. The Pache plants grow on high altitudes (2000-3000m) and give a mild tasting coffee.

Pacas

A natural variety of Bourbon that is mainly found in El Salvador.

Pacamara

A man-made hybrid of Pacas and Maragogype from El Salvador.

French Mission

A variation of Bourbon found in East Africa.

Catimor

Catimor coffee is a variation from the Middle East with a very sharp taste and smell. It is foten used to spice up blends of coffee.

Robusta

Robusta coffee plants were discovered in Congo and are nowadays much cultivated. Though less rich in taste than Arabica, it has the commercial advantage that it grows well in easy-accessible lowlands in combination with being resistant agains many diseases. The beans are smaller than the Arabica beans and less rich in flavour.

Kopi Luwak

The most famous Robusta from Indonesia. Collected from the droppings of the Civet cat.

Liberica

Liberica coffee originates from the forests of Liberia (hence the name) and Ivory Coast. It's beans are almost double the size of Arabica beans. Though the plant grows well in dry araes it is unfortunately very sensitive for diseases and therefore commercially less attractive.

Kape Barako

This coffee is almost solely found in the Philippines where it is even preferred over Arabica coffee. It has very large beans and is known for its strong taste and pungent aroma.

Excelsa

Excelsa coffee was discovered in 1904 and originates from around Lake Chad, a shallow lake found on the borders of Chad, Nigeria and Niger in Africa. One of the big advantages of Excelsa coffee is that it grows well in dry areas and is resistant agains many diseases. It is now also found on the Philippines and Java (Indonesia) and sometimes mistakingly sold as Kape Barako coffee.

Arabica - Robusta hybrids

Some attempts have been made to create new coffee plants as hybrids from Arabica and Robusta plants in order to get Arabica quality beans but with the toughness and resistance of Robusta plants. Generally the taste of those hybrids is far better than the taste of Robusta coffee but not as good as pure Arabicas. Hybrids of Arabica and Robusta are referred to as Arabustas.

Timor, Colombia, Castillo and Tabi

All hybrids created in Colombia in an attempt to make a coffee plant that is more resistant agaisn the leaf rust disease. Timor is the original hybrid between Arabica and Robusta while the others are further hybrids between Timor and various Arabica plants, mostly Caturra, Bourbon and/or Tipica.
