Most people think that coffee beans grow on trees. However, this is not the case. Coffee beans are actually the seeds of coffee cherries.
Coffee trees can grow up to 30 feet tall, but most are pruned to about 10-15 feet so that the coffee pickers can reach the coffee cherries.

The coffee plant, called Coffea, is a small bush that grows to about 10 feet tall. It has glossy dark green leaves and white flowers that have a jasmine-like scent. The coffee plant blooms and fruits all year round, but the peak harvesting season is between October and February. After the flowers are pollinated, small green berries or “coffee cherries” grow. It takes about 9 months for the cherries to ripen and turn red.
The coffee plant
The coffee plant is a bush or tree that can grow up to 10 meters (about 30 feet) tall, but is usually cut shorter. The leaves are dark green and glossy, and the flowers are white with a yellow center. The fruit, called a coffee cherry, turns red when it is ripe.
Inside the cherry are two beans. Coffee beans are roasted and ground to make the coffee we drink.
The coffee bean
Coffee beans are the seeds of berries that grow on coffee trees. The coffee tree is native to Ethiopia, and was first cultivated in Yemen. Coffee plants are now grown in more than 70 countries around the world, with Brazil being the largest producer.
Coffee beans are actually the pits of coffee cherries. Once the cherries are ripe, they are picked by hand and the beans are extracted. The beans are then dried, either in the sun or in large commercial drying machines.
After they are dried, the beans are hulled to remove the outer skin. The green coffee beans that remain are then graded and sorted before being roasted. Roasting is a key step in developing the flavor of coffee, and different roasts will produce beans with different flavors.
How coffee is grown
Coffee trees are actually bushes that can grow up to 10 feet tall, but are typically pruned to 6-8 feet to make picking the coffee cherries easier. Each tree can produce about 1 pound of coffee per year. The coffee tree flowers in the spring, and the cherries ripen by fall.
How coffee is harvested
Coffee is harvested by hand. The coffee cherries are picked and then sorted by ripeness. The ripe cherries are then pulped to remove the outer skin and the inner parchment. These two layers will be removed in one process called depulping. The coffee beans are then fermented in tanks for about 12-48 hours.
How coffee is roasted
Coffee roasting is the process of transforming coffee beans from their raw, green state into the roasted coffee that we know and love. While the specifics of roasting can vary slightly from one coffee roaster to another, the process generally follows these four key steps:
1. The coffee beans are heated until they reach their first crack.
2. The beans are then removed from the heat and allowed to cool slightly.
3. The beans are re-heated and roasted until they reach their second crack.
4. The beans are again removed from the heat and allowed to cool before being packaged and sold.
How coffee is brewed
Coffee is brewed by putting ground coffee beans in hot water and allowing them to steep for a period of time. The longer the coffee beans steep, the stronger the resulting coffee will be. The strength of the coffee can also be adjust by changing the grind of the beans, adding more or less water, and changing the brewing time.
The health benefits of coffee
Coffee beans are the seeds of coffee cherries. They are usually roasted before being brewed into coffee. Coffee beans contain caffeine, which can have positive and negative health effects.
Coffee beans contain antioxidants, which can protect your cells from damage. Antioxidants can also help prevent chronic diseases such as heart disease and cancer. However, too much caffeine can have negative effects, including anxiety, insomnia, nausea, irritability, and an increased heart rate.
If you enjoy drinking coffee but are concerned about its effects on your health, you may want to consider switching to decaffeinated coffee or limiting your intake.
The different types of coffee
There are two types of coffee plants – Arabica and Robusta. The Arabica coffee plant is native to Ethiopia and Yemen. It grows best in high altitudes, between 2,000 and 4,000 feet, in countries like Brazil, Colombia, Guatemala, and Peru. The Robusta coffee plant is native to Central Africa. Robusta coffee beans contain more caffeine than Arabica beans.
Coffee plants are evergreen shrubs or small trees that can grow up to 10 meters (about 33 feet) tall. Coffee plants usually have glossy green leaves that are 8-16 centimeters (3-6 inches) long and 2-5 centimeters (about 1 inch) wide. White or light green flowers bloom on the coffee plant. These flowers have a sweet fragrance and they grow in clusters of 10-15 blooms. After the flowers fall off, the coffee plant produces small oval berries called “coffee cherries.” It takes about 9 months for a coffee cherry to ripen.
The history of coffee
Coffee is a brewed drink prepared from roasted coffee beans, which are the seeds of berries from the Coffea plant. The genus Coffea is native to tropical Africa (specifically having its origin in Ethiopia and Sudan) and Madagascar, the Comoros, Mauritius, and Réunion in the Indian Ocean. Coffee plants are now cultivated in over 70 countries, primarily in the equatorial regions of the Americas, Southeast Asia, India, and Africa. The two most commonly grown are C. arabica and C. robusta. Once ripe, coffee berries are picked, processed, and dried. Dried coffee seeds (referred to as “beans”) are roasted to varying degrees, depending on the desired flavor. Roasted beans are ground and then brewed with near-boiling water to produce the beverage known as coffee.
