Coffee Beans: Dive in the aroma of coffee from seed to sip

Coffee is one of the most popular beverages in the world. Coffee beans are the seeds found inside the red or purple fruit known as the coffee cherry. Because of this, coffee beans are a key cash crop and export product, generating great revenue.

Coffee is believed to have originated in Ethiopia, where a goat herder named Kaldi discovered its revitalizing powers. It expanded to the Arabian Peninsula in the 15th century and by the 17th century, it had spread throughout Europe, stimulating intellectual discussions in coffeehouses. 

Coffee beans are now a global phenomenon, valued for their rich flavors and energizing properties. The maximum amount of coffee is produced in the equator region of the world and the majority of coffee beans are produced in Brazil, Vietnam, Colombia, Indonesia, and Ethiopia.

Types of coffee beans 

Coffee beans are classified into several varieties, each with its distinct flavor, aroma, and properties. Environmental factors like climate, elevation, and soil type can impact the flavor of coffee beans, thus the location of vegetation plays an important role in altering the characteristics and aroma of coffee beans.

There are four types of coffee beans. Arabica and Robusta are more common varieties of coffee beans while Liberica and Excelsa are comparatively lesser-known varieties. 

The four kinds of Coffee Beans 

Arabica 

Arabica coffee beans are considered the highest quality and most popular variety worldwide. These coffee beans are native to Ethiopia, although they are grown in a variety of tropical and high-altitude regions around the world. When roasted, the Arabica bean, which is dark brown and velvety to the touch, develops a broad flavor profile ranging from somewhat sweet and fruity to nutty. These coffee beans are generally oval, with a prominent center crease, and larger than Robusta beans. It is more expensive than Robusta due to its fragile characteristics.

Robusta 

Robusta is the second most popular kind. While Robusta beans are native to Sub-Saharan Africa, they are now grown primarily in Africa, Indonesia, and India. These coffee beans have a more intense and bitter flavor, with undertones of wood and nut.

Because of their bitter flavor, Robusta beans are frequently used in coffee blends to complement other coffee characteristics. This coffee bean is less common on its own, with the exception of instant coffee or espresso beans. These larger and more round coffee beans are rather used in blends to complement other coffee characteristics.

Liberica

Liberica coffee beans are native to central and western Africa, particularly tolerant of harsh temperatures, low elevations, and humid climates. These coffee beans are almond-shaped seeds with a flowery and slightly fruity aroma. It is known for its complex and unique flavor with woody, smoky, fruity, and floral undertones. While it may be used alone to make brewed coffee, the distinct flavor of such coffee beans makes it a popular mixing ingredient making a creative way to add a stronger flavor to the existing recipes.

Excelsa

Excelsa beans were first discovered in Africa, but today the majority of them are grown nearly exclusively in Southeast Asia. These coffee beans, which have a somewhat extended oval shape grow well at medium altitudes and prefer warm climates. Excelsa coffee beans are noted for their extremely complex flavor profile. They are frequently used in coffee blends due to their tart, fruity, and complex flavor to add depth to the coffee. These unique coffee beans combine the light and dark roast traits.

Harvesting of coffee beans

Harvesting coffee beans is a crucial step in coffee production since it affects the quality of the finished product. Coffee cherries, which enclose the beans, are usually harvested when they transform from green to a bright red or yellow, indicating ripeness. The ripening time varies from 6-8 months for Arabica and 9-11 months for Robusta.

Two methods of harvesting 

The following are two primary methods of harvesting coffee beans- 

Hand Picking 

Selective Picking: Workers handpick just ripe cherries, leaving unripe ones to mature. This labor-intensive method yields high-quality beans and is frequently used in specialty Arabica coffee.

Strip Picking: Entire cherry branches are harvested at once, giving both ripe and unripe fruit. This is faster and less intensive, but it requires post-harvest sorting to separate high-quality beans.

Mechanical Harvesting 

Mechanical coffee harvesting uses machines to efficiently remove coffee cherries from trees, making it perfect for large-scale plantations on level terrain. The machines shake branches or utilize stripping mechanisms to release cherries, which are then collected in trays or on tarps. This process is faster and less expensive than human harvesting, enabling large-scale production. However, it frequently harvests both ripe and immature cherries, necessitating post-harvest sorting to ensure quality. While newer machines are intended to reduce tree damage, they are less exact than hand-picking and unsuitable for quality coffee. Mechanical harvesting is commonly employed in places like Brazil.

How long do coffee beans last 

The shelf life of coffee beans depends on whether they are roasted or unroasted and their exposure to air, heat, light, and moisture and determines how long do coffee beans last.

Roasted coffee beans undergo a ‘degassing’ process, which replaces carbon dioxide with oxygen. Too much carbon dioxide in the coffee can give it a sour, acidic flavor, which is why most roasters recommend waiting at least a few days after the roast date to brew. Roasted coffee beans stay fresh for a week or two after being exposed to air and moisture. If proper care is taken it can even last for a month giving a more aromatic and robust flavor.

Due to long storage times, qualitative deterioration in the coffee beans occurs. The unroasted or green coffee beans may be stored for up to twelve months without losing flavor or aroma if kept stable, cold, dark, and pest-free.

Storing the coffee beans in the freezer can help to keep them fresher for longer, but they can also impair the flavor and aroma. The moisture produced by this condensation infiltrates the coffee beans.

Impacts of coffee beans 

Coffee has become a staple beverage in a large population’s daily life. The impact of coffee beans has multiple dimensions, including health, economy, and society.
