The World of Coffee: An Exploration of Varietal and

Rare Coffee Beans

Do you ever wonder why your coffee tastes different from one caf to another? Or have you been interested in exploring the world of coffee, but the terms you encounter make you feel lost?

Fear not, dear reader, as we navigate the world of coffee together. At the heart of coffee are the beans, which come in two main varieties: Arabica and Robusta.

Arabica Coffee Beans

Arabica, or Coffea Arabica, is the most commonly cultivated coffee plant in the world, comprising around 60% of global coffee production. Arabica thrives in high altitude regions with temperate climates, typically between 1,800 to 6,500 feet above sea level.

The flavor profile of Arabica beans tends to be mild, with a lower caffeine content. There are various subtypes of Arabica coffee beans, including Typica, Bourbon, Caturra, and Mundo Novo.

Typica, the original Arabica variety, is known for its mellow, floral notes, while Bourbon brings a distinctive sweetness to the cup. Caturra, a genetic mutation of Bourbon, is a dwarf variety that produces a bright, fruity cup, while Mundo Novo is a hybrid of Typica and Bourbon that is gaining popularity due to its balanced flavor notes.

Robusta Coffee Beans

Robusta, or Coffea Canephora, is the second most commonly cultivated coffee plant, accounting for about 40% of global coffee production. Robusta beans are typically grown in hotter, low altitude regions and are highly resistant to pests and diseases.

Unlike Arabica beans, Robusta beans have a higher caffeine content and are known for their strong, full-bodied flavor.

Rare Coffee Beans

Apart from the popular Arabica and Robusta beans, there are other varieties that are less well-known but equally fascinating. Liberica, or Coffea Liberica, is a rare coffee species that represents under 1% of global coffee production.

With a unique flavor profile that ranges from woody to floral, Liberica beans have a larger and more irregular shape compared to Arabica and Robusta. The Liberica tree is also unique, with large leaves and tall, robust branches.

Excelsa, or Coffea Excelsa, is another lesser-known coffee species, often mistaken for a subtype of Liberica. Excelsa beans have a tart, fruity flavor and a low acidity that makes for a complex, rich cup.

This bean is grown primarily in Southeast Asia and has gained popularity among coffee enthusiasts in recent years.


Whether you prefer Arabica, Robusta, Liberica, or Excelsa, understanding the different types of coffee beans can help you appreciate the flavors and aromas of your preferred brew. Each coffee variety has its unique characteristics, from the place it is grown, down to its flavor profile and aroma.

The next time you sip your coffee, take the time to appreciate the journey it has taken from the farm to your cup. Happy tasting!

Processing and Roasting: An Essential Guide to Coffee Beans

Coffee is an art, and the process of transforming coffee cherries into the aromatic, invigorating drink we love is complex and multifaceted.

Understanding how coffee is processed and roasted can enrich your appreciation and experience of coffee. In this article, well explore the three primary processing methods of coffee: the natural process, washed process, and pulped natural/semi-washed process.

Well also delve into the different roasts available, from dark to light and everything in between.

Processing Coffee Beans

Natural Process

The natural process, also known as the dry process, is the oldest method of processing coffee. As the name suggests, the natural process involves drying the whole coffee cherries in the sun, without removing the pulp.

The cherries are collected and spread out in thin layers on patios or drying beds. As the cherries dry, theyre turned over to ensure even drying and prevent mold growth.

Once the cherries are completely dry, theyre hulled, revealing the coffee beans. The natural process results in a coffee with a fruity flavor profile, with notes of berries, cherries, and tropical fruit.

Washed Process

The washed process, also known as the wet process, involves removing the pulp of the coffee cherries before the beans are dried. After harvest, the cherries are sorted, and the ripe ones are separated from the unripe ones.

The fully ripe cherries are then passed through a pulping machine, which separates the pulp from the coffee beans. Next, the beans are submerged in water and left to ferment for a specified period, typically between 12 to 48 hours, depending on the desired flavor profile.

This fermentation process breaks down the remaining mucilage and sugars, allowing the coffee beans to absorb more water. The beans are then washed to remove any remaining pulp, and some farmers opt to use machines to clean and sort the beans to ensure consistency.

Finally, the beans are dried on patios or drying beds. The washed process results in a coffee with a clean, bright flavor profile, with notes of citrus, flowers, and chocolate.

Pulped Natural/Semi-washed Process

The pulped natural/semi-washed process is a hybrid of the natural and washed methods. The pulped natural method involves removing the pulp but leaving some of the fruit residue on the beans before theyre dried.

The semi-washed method involves removing some of the fruit residue before drying the beans. This method can produce a coffee with the body of a natural, but with the clarity of a washed.

Roasting Coffee Beans

Dark Roast

Dark roast coffee is typically roasted for a longer period than light or medium roasts. The longer roasting period leads to a dark, almost black color of the beans and produces a coffee with notes of caramel, chocolate, and smoke.

However, darker roasted coffee can lack the complexity of light or medium-roasted coffee. Often, very dark roasts are used for lower quality beans with subtle flavors or badly damaged beans.

To appreciate the subtle flavors of high-quality beans, you may want to consider a light or medium roast.

Light and Medium Roast

Light and medium roasts are gaining popularity due to their bold, complex flavors and aromas. Light or medium roasted coffees are roasted for a shorter amount of time than dark roast coffee, typically between 9-14 minutes.

The shorter roasting period allows the beans to retain more of their natural flavors and aromas, producing a coffee with notes of floral, berries, and nuts. A slower roasting schedule at these levels can lead to even more complex flavors.


From the processing of coffee beans to their roasting, the journey of coffee from farm to cup is a complex process. Understanding the nuances of each step helps us appreciate the unique notes and aromas of the coffee we drink.

Whether you prefer a light roast, a natural process, or something else entirely, exploring the nuances of coffee can be an enjoyable experience for any coffee lover. Altitude, Sunlight, and

Soil: The Science of Coffee

Coffee is an agricultural product, and the environment in which coffee plants grow affects the flavor and quality of the beans they produce.

In this article, well discuss the impact of altitude, sunlight, and soil on coffee. We will also explore the art of coffee blending, which allows for a balance of flavors and aromas.

Altitude and Coffee

One of the most significant factors affecting the flavor and quality of coffee is altitude. Coffee plants thrive in high elevation regions, typically between 1,800 to 6,500 feet above sea level.

At high elevations, cooler temperatures slow the growth of coffee plants, leading to denser beans and resulting in a more complex flavor profile. The slower growth of the plants also leads to a sweeter, fruitier taste in the beans.

In contrast, coffee grown in lower elevations, often results in less complex flavor profile.

Sunlight and Shadow

Sunlight is another key factor in coffee growth. Coffee plants require sunlight to grow, but too much sunlight can result in bitter, unpleasant coffee.

In areas with intense sunlight, farmers may use shade trees to regulate the amount of sunlight that falls on their coffee plants. Shade trees help to maintain appropriate temperatures and moisture levels, allowing for a slower growth rate of the coffee plants which produces a sustainable, complex flavor profile.


The soil in which coffee plants grow has a significant impact on the flavor of the coffee beans. Fertile soil rich in organic matter provides necessary nutrients for coffee plants to grow, leading to a deeper, more complex flavor.

Coffee Blends

Coffee blends are a mix of two or more different types of coffee, blended together to create a balanced flavor profile. Blends are created by roasters to take advantage of the unique flavor profiles of different types of coffee, and to offer consumers a consistent product.

Definition of Coffee Blend

A coffee blend involves the combination of different coffee beans from different origins to produce beans with a unique set of flavor characteristics. Coffee blends may also involve combining different roast levels.

Coffee roasters use blends to create a coffee that is balanced in flavors that appeal to a wide range of palates and a consistent product that can be served all year round.

Arabica and Robusta Blend

One of the most popular coffee blends is a mixture of Arabica and Robusta beans. Arabica beans provide a robust, smooth, and fruity flavor, while Robusta beans give the coffee a bold, bitter taste.

The combination results in a well-rounded, full-bodied coffee with sweet and bitter notes, and especially popular in espresso blends.


From the environment in which coffee plants grow to the roasting and blending, many factors work together to create the unique flavor of coffee. Understanding these nuances can help us appreciate the intricacies of this beloved beverage and deepen our appreciation for the expertise of the people who bring it to us.
