History of Coffee Beans

Origin and Discovery

The history of coffee beans dates back to the ancient coffee forests on the Ethiopian plateau. Legend has it that Kaldi, a goat herder, discovered the effects of the coffee beans when he noticed his goats’ increased energy levels after eating these mysterious red fruits. He took the red fruits to a nearby monastery, where the monks tried boiling them, resulting in a bitter-tasting drink that helped to keep them alert throughout their evening prayers.

This is how coffee was first discovered and began to spread. However, there are alternative versions of the story with different details, including one that attributes the discovery of coffee to Sheikh Omar, a physician-priest, who had been exiled to the desert in Ethiopia. To survive, he boiled the berries of a coffee plant and inadvertently discovered the energizing effects of the fruits.

Upon his return to the city, he quickly gained popularity for his coffee and eventually became the patron saint of coffee. While archaeological findings and written records don’t fully validate this story, it is known that the coffee plant originated from Ethiopia. The name “coffee” derives from the Arabic word “qahwah” and from the Kaffa region in Ethiopia. Research shows that coffee plants have been cultivated in Ethiopia since the 9th century.

The invention of coffee drinks is believed to have started in the medieval period, where people would create an infusion by boiling water and the coffee plant’s fruits. Over time, this technique evolved, and coffee drinkers began roasting the beans of the coffee tree and grinding them for brewing.

Spread of Coffee Cultivation

The cultivation of coffee plants spread from Ethiopia to nearby regions by the 15th century. Coffee cultivation first took root in the Arabian Peninsula, specifically Yemen. The cultivation and trade of coffee were fiercely protected by the Arabs for several centuries, and they would not allow the live coffee trees to be exported. Yemeni farmers even implemented a process to partially boil the beans, making them infertile, to maintain their monopoly on coffee cultivation.

Despite these measures, the secret of coffee cultivation started spreading across the globe as traders and travelers discovered the coffee drink. In the 17th century, Baba Budan, a revered Muslim trader, smuggled live coffee beans from Yemen to India by hiding them in his clothes. This act contributed to the widespread coffee cultivation in India, which has become one of the significant global coffee producers.

The Dutch, who had already established coffeehouses in New Amsterdam (currently known as New York City), played a significant role in spreading coffee cultivation. They obtained live coffee plants from Yemen and began cultivating them in Java, Indonesia’s island, in 1699. The Dutch East India Company rapidly started exporting coffee beans from Java to Europe, which propelled coffee’s popularity as a beverage and trade commodity in the early 18th century.

From the Dutch colonies, coffee beans found their way to the Caribbean and Central and South America. In 1718, one live coffee plant was gifted to the French royal court, then a French naval officer named Gabriel de Clieu managed to transport a cutting from the plant to Martinique in 1720. This single plant served as the origin for coffee plantations in the Caribbean, Central and South America, with Brazil becoming the largest coffee-producing country in the world.

Nowadays, coffee stands as one of the most produced and consumed beverages in the world. With its history of discovery, secret cultivation, and trade, it has shaped the global economy and has become an essential element of various cultures across continents.

Understanding Coffee Beans

Coffee is one of the most popular and widely consumed beverages in the world. The beans used to make coffee come from the seeds of the Coffea plant, and their characteristics have a significant impact on the final taste and aroma of the brewed coffee.

Arabica and Robusta Species

There are multiple species of coffee beans, but the two main ones are Coffea arabica (Arabica) and Coffea canephora (Robusta). They have a few major distinctions that set them apart:

  1. Arabica beans are generally considered to be higher in quality and have a more delicate, nuanced flavor profile. They have less caffeine than Robusta beans, which can make them less bitter and acidic. They are also oval-shaped and have a curved crease on one side.

  2. Robusta beans, on the other hand, are typically seen as having a stronger, more bitter flavor, and they have higher caffeine content. This higher caffeine level can create a more robust and harsher taste. They are rounder, smaller, and have a straight crease on one side.

Many coffee blends available in the market have a mixture of both Arabica and Robusta beans, aiming to strike a balance between the flavors and characteristics of each species. There are also different varieties within each species, which can further influence the taste and aroma of the beans.

Geographical Factors

The geographical factors of where coffee beans are grown are often referred to as their “terroir.” These factors affect the flavor of the beans and include altitude, shadows, climate, and temperature.

Altitude and Shadows

The altitude at which coffee is grown can significantly impact the flavor and overall quality of the beans. Higher altitudes generally produce slower-growing beans with more complex and acidic flavor profiles. Coffea arabica thrives at altitudes between 2,000 and 6,000 feet above sea level, whereas Coffea canephora (Robusta) can grow at lower elevations.

Shadows also play a part in coffee cultivation. Some of the best coffees are grown in the shade, under larger trees, as the protection from direct sunlight results in slower maturation of the cherries. This longer growing period allows for the development of richer flavors.

Climate and Temperature

Coffee plants are sensitive to their environment, and slight changes in climate or temperature can affect their growth and flavor development. Generally, coffee plants prefer an average temperature between 60 and 70 degrees Fahrenheit and require roughly 60 inches of rainfall each year.

Regions such as Central and South America, Africa, and Indonesia are known for producing high-quality coffee beans, partly due to their ideal climate conditions. However, climate change is posing a new threat to coffee cultivation globally, as shifts in temperature and rainfall patterns can cause issues with pests, diseases, and crop yield.

Anatomy of a Coffee Bean

A coffee bean is made up of several layers that each contribute to the flavor of the brewed coffee. The outermost layer is the parchment skin, which is removed during processing. Underneath the parchment skin is the silver skin, a thin, delicate layer that often remains on the bean even after roasting.

The actual beans themselves are made up of a combination of sugars, starches, proteins, oils, lipids, organic acids, and various other compounds. These components contribute to the flavors, bitterness, acidity, and aroma of the final brew. When coffee beans are roasted, these compounds undergo chemical reactions, such as the Maillard reaction and caramelization, which result in the development of new flavors and aromas.

Understanding the characteristics and variables of coffee beans is essential to appreciating the complexities of their flavors and aromas. It helps us make informed choices when selecting raw beans for roasting or when purchasing a bag of our favorite blend to brew at home.

Coffee Bean Processing Methods

Coffee beans are the seeds of the Coffea plant, and with the global demand for coffee, there are several methods to process coffee beans. Each method affects the taste and properties of the final coffee.

Wet Process

The wet process is a method that uses water to remove the coffee fruit’s outer layers and pulp before drying the beans. This method is considered to produce cleaner and consistent coffee flavors. There are two main sub-methods in the wet process: the washed process and the honey process.

Washed Process

The washed process, also known as the fully washed or wet processing, is the most common method of coffee bean processing. It involves the use of water and a pulping machine or depulper to remove the coffee cherry’s outer skin and most of its pulp while still fresh.

The beans, still with some mucilage (a sticky substance) on them, are then fermented in water tanks for about 24 to 72 hours. During this time, natural enzymes break down the remaining mucilage. After the fermentation, the beans are rinsed to remove any remaining mucilage and to clean them. Once washed, they go through a quality check to remove any damaged or defective beans.

The coffee beans are then spread out to dry on raised beds, cement patios, or drying machines until they reach the desired moisture content of around 11%. The washed process produces a bright and crisp acidity in the final coffee, with a medium body and distinct, clean flavors. It is favored in many countries, such as Colombia, Kenya, and Costa Rica.

Honey Process

The honey process is a variation of the wet process, where the coffee cherry’s outer skin is removed, but the mucilage is not entirely washed off before drying. The beans are allowed to dry with the remaining mucilage, which gives them a sticky, honey-like coating, hence the name “honey process”. There are several types of honey process, such as yellow, red, and black honey, depending on the amount of mucilage left on the beans and the drying conditions.

The honey process produces a coffee with a delicate balance of flavors, combining the fruity notes of dry-process coffee and the clean acidity of washed-process coffee. This method is popular in countries like Costa Rica, El Salvador, and Nicaragua.

Dry Process (Natural)

The dry process, also known as the natural process or sun-dried process, is the oldest and simplest coffee bean processing method. In this method, the coffee cherries are laid out in the sun to dry for about 2 to 4 weeks, with the beans still inside the fruit. The cherries are turned regularly to ensure even drying and to prevent spoilage.

Once the cherries have reached the desired moisture content of 11% to 12%, they are hulled to remove the dried fruit and outer layers. This method produces coffee beans with a more prominent body, lower acidity, and fruity, winey flavors. The dry process is commonly used in regions with limited access to water, such as Ethiopia, Yemen, and Brazil.

Semi-Washed Process (Pulped Natural)

The semi-washed process, also known as the pulped natural process, is a combination of the washed and dry processes. The coffee cherry’s outer skin and some pulp are removed, like in the washed process, but the remaining mucilage is left on the beans as they are dried, similar to the honey process.

The result is a coffee that has the body and sweetness of the dry process, combined with the acidity and cleanliness of the washed process. It produces a well-balanced coffee flavor without the extreme fruity notes found in naturally processed coffees. This method is gaining popularity, particularly in Brazil and some parts of Colombia.

Experimental Processing Methods

In addition to the traditional coffee bean processing methods, there are several experimental methods driven by the desire for new flavors and sustainable practices. Some examples of these methods include:

  1. Anaerobic Fermentation: This method involves fermenting the beans in airtight, oxygen-free environments for a controlled period, promoting the development of unique flavor profiles.

  2. Carbonic Maceration: Inspired by wine-making techniques, this method allows the cherries to ferment with added carbon dioxide, enhancing the fruity flavors of the coffee and creating a distinct aromatic profile.

These experimental processing methods illustrate that there are endless possibilities for innovation within the coffee industry, appealing to coffee lovers seeking new experiences in their cup. The various coffee bean processing methods significantly influence the final coffee flavor, making the world of coffee diverse and fascinating.

Roast Levels and Flavor Profile

The roast level of coffee beans has a significant impact on the flavor profile of the brewed coffee. As the beans are roasted, they undergo a complex process, known as the Maillard reaction, where sugars and amino acids react to produce hundreds of flavor compounds. Roasting coffee beans at different levels will result in differing taste characteristics. Here’s a brief outline of the common roast levels:

  1. Light Roasts: Light roast coffee beans have a light brown color and a bright, acidic flavor profile. These beans are not roasted long enough for the oils to break through the surface, so they have a dry appearance. Light roasts showcase the original flavor characteristics of the coffee beans, often revealing fruity, floral, or herbal notes.

  2. Medium Roasts: Medium roast coffee beans exhibit a rich medium-brown color and balanced flavor profile, with a combination of the beans’ inherent flavors and the roasting process’s influences. They are slightly sweeter than light roasts and often have a mellow acidity, with notes of caramel, nuts, or chocolate.

  3. Dark Roasts: Dark roast coffee beans are roasted longer, resulting in a dark, oily appearance and bold, intense flavors. These beans have lower acidity and an increased bitterness, with the roasting process’s flavors often overshadowing the beans’ original taste characteristics. Dark roasts commonly exhibit flavors such as chocolate, smokiness, or even burnt notes.

Roasting Equipment and Techniques

Roasting coffee beans requires the application of heat to achieve a chemical reaction that develops the coffee’s flavors and aroma. There are various roasting equipment options available, ranging from simple and affordable methods to professional-grade machines. Here are some common roasting equipment options:

  1. Home Oven or Stovetop: One of the easiest and most affordable methods to roast coffee beans at home is using an oven or stovetop with a perforated baking sheet or a stovetop popcorn maker. This requires careful monitoring and frequent stirring to ensure an even roast.

  2. Air Popcorn Popper: Air popcorn poppers can be used as an effective home coffee roaster, as they utilize hot air to evenly roast the coffee beans.

Grinding coffee beans is essential for the proper extraction of flavors during brewing. The particle size and consistency of the grounds can affect the taste and strength of the coffee. There are two main types of coffee grinders – blade grinders and burr grinders – each with their own advantages and disadvantages.

  1. Blade Grinders: These grinders use a spinning blade to chop the coffee beans into various particle sizes. They are usually more affordable and compact, making them a popular choice for home use. However, blade grinders do not produce a consistent grind, which can result in uneven extraction and poor taste.

  2. Burr Grinders: Burr grinders, on the other hand, use two abrasive surfaces (burrs) that rotate and crush the coffee beans into a more uniform particle size. These grinders typically produce a better and more consistent grind, leading to improved flavor and extraction. However, they can be more expensive and large compared to blade grinders.

The ideal grind size depends on the brewing method, as different methods require varying particle sizes to achieve proper extraction:

  • Coarse: Coarse grounds are best for brewing methods such as French press and cold brew, where water is in contact with the coffee for a longer period.
  • Medium: Medium grounds are suitable for drip coffee makers and pour-over methods.
  • Fine: Fine grounds are commonly used for espresso machines, as they require a consistent and fine grind to ensure proper extraction under high pressure.
  • Extra Fine: Extra fine grounds are typically utilized for Turkish coffee, where the grounds are almost powdery.

Properly roasting and grinding coffee beans can significantly enhance your coffee experience by allowing you to fine-tune the flavor and strength of your brew. Experiment with different roast levels, equipment, and grind sizes to discover your perfect cup of coffee.

Sustainability and Eco-Friendly Practices

The coffee industry is continuously seeking ways to improve its sustainability and eco-friendly practices. These efforts are critical in addressing the increasing concerns about environmental degradation, climate change, and fair remuneration for coffee growers.

Some of the key areas that are being explored include the production of shade-grown and organic coffees, implementation of fair and direct trade systems, and researching the environmental impact of coffee cultivation on climate change. 

Shade Grown and Organic Coffees

Shade-grown coffee refers to coffee plants grown under the natural shade of other trees rather than in full sunlight. This cultivation method has been shown to have numerous benefits for the environment and local ecosystems. For instance, it promotes biodiversity by providing a habitat for various species of birds and insects, which aid in the natural control of pests that would otherwise damage the coffee crops.

Additionally, the presence of other trees in the coffee plantation helps to prevent soil erosion, maintain soil fertility, and capture more carbon dioxide, positively contributing to climate change mitigation efforts. Organic coffee production, on the other hand, requires that no synthetic fertilizers or pesticides are used in the cultivation process.

Fair Trade and Direct Trade certifications are designed to ensure that coffee growers receive fair compensation for their work, contribute to local community development, and promote environmentally sustainable practices. The Fair Trade system guarantees a minimum price for coffee producers, which helps them to cover their production costs and provide for their families.

It also includes social and environmental standards that encourage the development of local communities and the preservation of natural resources. Direct Trade, on the other hand, involves a more direct relationship between coffee growers and roasters or buyers.

This approach allows farmers to negotiate better prices for their coffee beans and eliminates the need for intermediaries in the supply chain. Direct Trade also emphasizes transparency and open communication between coffee producers and buyers, which can contribute to building long-term relationships and fostering improved environmental practices.

Both Fair Trade and Direct Trade systems have gained significant traction in recent years, demonstrating the growing concern among consumers and industry stakeholders for responsible and sustainable coffee production. By supporting these certifications, coffee drinkers can contribute to the well-being of coffee-growing communities and the preservation of the environment.

Environmental Impact and Climate Change

Climate change poses a significant threat to the coffee industry, as rising temperatures and extreme weather conditions can have severe consequences for coffee production. For instance, factors such as prolonged droughts, excessive rainfall, and increased temperatures can lead to lower coffee yields, increased disease prevalence, and changes in coffee bean quality.

It is essential for coffee producers to assess their environmental impact and take steps to mitigate the effects of climate change on their crops. This can be achieved through implementing sustainable farming practices, investing in research and development, and participating in projects that support environmental conservation and carbon sequestration.

Additionally, governments and international organizations can play a vital role in promoting the adoption of sustainable practices and investing in climate-resilient coffee varieties.
