What is Specialty Coffee?

Specialty coffee refers to a category of high-quality coffee that is distinct from mass-produced, commercial coffee. The term “specialty” is used to emphasise the exceptional characteristics, unique flavours, and premium quality of coffee beans. Several factors contribute to coffee being classified as specialty, including the quality of the beans, flavour profiles, processing methods, and sustainability.

The term “specialty coffee” represents a commitment to excellence throughout the entire coffee production chain – from cultivation to brewing. It has become a cultural movement that values the unique qualities of each coffee bean and fosters a deeper appreciation for the art and craft of coffee.

Coffee Growing Regions

In the vast expanse of our coffee-centric globe, certain regions stand as veritable treasure troves, and provide some of the world’s best beans. These coffee growing regions are where climate, altitude, and soil combine to create the perfect environment for a top-quality product.

Global Coffee Belt

The equatorial band known as the “Coffee Belt” encompasses regions between the Tropics of Cancer and Capricorn. Within this belt, we find the coffee-growing regions that have become synonymous with excellence in coffee production. From the lush hills of Ethiopia to the volcanic soils of Central America, each location contributes its unique signature to the beans it cultivates.

Flavour Alchemy

The interplay of climate, altitude, and soil is the environmental balance that creates such distinctive flavours for coffee beans. Let’s explore how these factors shape the flavour profile:

1. Climate: The balance of sun and rain, along with temperature variations, affects how coffee cherries ripen. A slower maturation process often results in more complex flavours. For instance, Ethiopian coffees, grown under diverse microclimates, offer a spectrum of fruity, floral, and wine-like notes.

2. Altitude: The altitude at which coffee is grown plays a pivotal role in flavour development. Higher altitudes, with cooler temperatures and slower maturation, encourage the formation of acids and sugars. Coffees from regions like Colombia’s Andean slopes boast bright acidity and nuanced sweetness.

3. Soil Composition: The minerals and nutrients present in the soil influence the coffee plant’s growth and, consequently, the flavour profile. Volcanic soils, such as those found in parts of Costa Rica, contribute to coffees with a distinct brightness and clarity.

Notable Regions

1. Ethiopia: Informally known as the ‘birthplace of coffee’, Ethiopia is known for its diverse heirloom varieties and complex, fruity flavours.

2. Colombia: Renowned for its high-altitude Arabica beans, offering a well-balanced cup with bright acidity.

3. Costa Rica: A country celebrated for its clean, sweet coffees with hints of citrus and tropical fruit.

4. Kenya: Produces bold and full-bodied coffees, often characterised by a juicy wine-like flavour.

Harvesting and Processing: Crafting the Essence of Specialty Coffee

The journey from cherry to cup begins with the process of harvesting. This is where the best, ripe coffee cherries are selected to lay the foundation for a specialty coffee bean.

Harvesting Coffee Cherries

Harvesting demands both precision and timing. Coffee cherries do not ripen uniformly, so require skilled hands to selectively pluck only the ripest cherries. In many regions, this is still done by hand to ensure the cherries are picked at the peak of ripeness. This careful curation sets the stage for the quality of the beans.

Processing Methods

Washed (or Wet) Processing

Process: After harvesting, cherries are swiftly pulped to remove the outer skin, leaving behind the beans encased in mucilage.

Fermentation: The beans with mucilage undergo a controlled fermentation process, breaking down sugars and imparting distinct flavours.

Washing and Drying: The beans are thoroughly washed to remove any remaining mucilage, followed by drying under the sun or in mechanical dryers.

Flavour: Washed processing often yields coffees with cleaner profiles, bright acidity, and pronounced floral or fruity notes. The clarity in flavours is attributed to the removal of mucilage during fermentation and washing.

Natural (or Dry) Processing

Process: The whole cherries are laid out to dry in the sun, allowing the beans to absorb the sugars and flavours from the fruit.

Drying: This method takes longer as the cherries dry with their skins intact, fostering a unique profile with fruity, wine-like, or even fermented notes.

Hulling: Once dried, the outer layers are removed to reveal the beans.

Flavour: Natural processing methods infuse the coffee with intense, fruity flavours, that sometimes border on wine-like or fermented. The extended contact with the cherry during drying imparts a full-bodied richness and complexity.

Honey Processing

Process: A hybrid of washed and natural methods, honey processing involves removing the skin and some pulp, leaving a sticky, honey-like layer on the beans.

Drying: The beans are dried with this residual layer, influencing the sweetness and body of the coffee.

Variations: Honey processing comes in different degrees—white, yellow, red, or black—referring to the amount of pulp left on the beans during drying.

Flavour: Offers a middle ground, showcasing sweetness and body with the potential for nuanced flavour profiles. The degree of honey residue left on the beans allows for a spectrum of tastes, from delicate and tea-like to bold and syrupy.

Quality Grading: Ensuring Excellence

The journey from bean to brew is a meticulous task that is guided by the discerning eyes and palates of experts. Quality grading, a crucial stage in this process, serves as the compass that navigates coffee lovers towards perfection. So, what criteria define the quality of coffee beans? 

Criteria for Quality Grading

Bean Size and Density: Larger beans are often associated with higher quality, as they tend to develop more complex flavours during the roasting process. Density is also crucial, indicating the concentration of flavours within the bean.

Moisture Content: The moisture content in coffee beans must be carefully controlled. Beans with an optimal moisture level not only ensure a more even roast but also contribute to the preservation of flavours.

Freedom from Defects: Quality beans should be free from any defects, such as mould, insect damage, or irregularities in shape. Defects can significantly impact the taste and aroma of the coffee.

Cupping Scores: Coffee cupping, a systematic method of tasting and evaluating coffees, involves scoring various attributes such as acidity, body, flavour, and aftertaste. The overall cupping score is a pivotal factor in determining the quality of the coffee.

Origin and Terroir: The region where coffee is grown plays a significant role in its grading. Certain origins are renowned for producing coffees with unique and sought-after flavour profiles.

The Roasting Process

The roasting process emerges as the moment where the true character of coffee is revealed. This pivotal stage not only imparts the beans with their distinct hue but also unlocks the flavours that are so crucial for a satisfying brew. Let’s explore how the roasting process elevates coffee from a humble seed to a sensory delight.

Green to Gold: The journey begins with green coffee beans, their raw, unroasted state preserving the potential for a myriad of flavours. As the beans meet the heat of the roaster, the beans expand, crack, and undergo a mesmerising transformation, turning from green to various shades of brown.

Maillard Reaction: At the heart of the roasting process lies the Maillard reaction, a complex chemical reaction between amino acids and sugars. This reaction not only imparts colour to the beans but also generates a spectrum of flavours, unlocking the notes and aromas that define the character of the coffee.

Different Roasting Profiles and Their Impact

Light Roast

Characteristics: Light roasts preserve the inherent flavours of the bean, offering a crisp acidity and showcasing the unique terroir and varietal characteristics. They often retain floral, fruity, or tea-like notes.

Impact on Taste: Light roasts provide a vibrant, nuanced experience, allowing the drinker to savour the intricacies of the coffee’s origin.

Medium Roast

Characteristics: Balancing sweetness and acidity, medium roasts offer a broader flavour profile with a touch of caramelization. They strike a harmony between the inherent bean flavours and the roasting process.

Impact on Taste: Medium roasts are a popular choice for those seeking a well-rounded cup, where acidity is tempered by a fuller body and subtle sweetness.

Dark Roast

Characteristics: Dark roasts feature bold, robust flavours with pronounced bitterness. The longer roasting time brings out deep, smoky, and chocolatey notes, often overshadowing the original characteristics.

Impact on Taste: Dark roasts appeal to those who prefer a more intense and full-bodied cup, where the roasting process plays a dominant role in shaping the flavour.

Single-Origin vs. Blends

Single-Origin: Roasters may choose a light to medium roast for single-origin coffees to highlight the unique flavours of a specific region.

Blends: Blends may involve a combination of roasting profiles to achieve a balanced and complex flavour profile.

It should also be noted that the roasting style does not have a link to the caffeine content in coffee. Dark roast coffee is only bolder in flavour – not in caffeine.

The Art of Precision

The roasting process is one of the most important steps of the process when it comes to getting the flavour right. Perfect roasting lies in the ability to balance the preservation of intrinsic flavours with the development of desirable roast characteristics – no small task.

The roaster’s craft should coax out the nuances hidden within the coffee while paying homage to the origin and varietal intricacies.
