Coffee, the world’s favorite morning beverage, is more than just a caffeine fix. It’s a complex product with nuances in flavor, aroma, and origin that can be scientifically evaluated. When you’re working in the coffee trade, whether as a buyer, seller, roaster, or barista, the ability to accurately rate coffee becomes essential for quality control, pricing, and communication. This guide explores the crucial aspects of rating coffee on trade, focusing on the methodologies and criteria used to assess its quality.
Understanding Coffee Cupping: The Foundation of Evaluation
Cupping is the industry standard method for objectively evaluating coffee. It’s a systematic process that minimizes variables, allowing professionals to focus solely on the coffee’s inherent qualities. Mastering cupping is fundamental to rating coffee effectively.
The Cupping Process: A Step-by-Step Guide
The cupping process involves several stages, each designed to extract and analyze specific characteristics of the coffee. The goal is to remain objective, using your senses to paint a detailed picture of the coffee’s profile.
First, the green coffee beans are visually inspected for defects like broken beans, insect damage, or discoloration. These defects can significantly impact the final cup quality. Any significant defects are noted.
Next, a measured amount of green coffee is roasted to a specific profile, typically a light to medium roast. This roast level is chosen to highlight the coffee’s origin characteristics without introducing excessive roast flavors. The roasted coffee is then ground to a medium-coarse consistency, similar to that used for drip brewing.
The ground coffee is placed in cupping bowls, usually with a predetermined ratio of coffee to water. Hot water, ideally between 200-205°F (93-96°C), is poured over the grounds to saturate them completely. This process, known as “blooming,” releases aromas and allows the coffee to degas.
After a few minutes, the crust that forms on top of the coffee is gently broken using a cupping spoon. As the crust is broken, the cupper carefully evaluates the aroma, known as the “break.” The aroma is a crucial indicator of the coffee’s potential flavor profile.
Using two cupping spoons, the cupper removes any remaining grounds and foam from the surface of the coffee. This ensures a clean cup for tasting.
The coffee is then slurped from the spoon, spraying it across the palate to ensure it reaches all taste receptors. The cupper focuses on the flavor, acidity, body, and aftertaste of the coffee.
Throughout the process, the cupper takes detailed notes on each aspect of the coffee’s profile. These notes are then used to assign a score and develop a comprehensive description of the coffee.
Why Cupping is the Industry Standard
Cupping provides a consistent and objective framework for evaluating coffee. By following a standardized protocol, cuppers can minimize bias and ensure that their evaluations are reliable and comparable. This is especially important in the coffee trade, where accurate and consistent quality assessments are essential for making informed decisions about buying, selling, and roasting coffee.
Key Attributes to Evaluate in Coffee
When rating coffee, several key attributes are evaluated. These attributes contribute to the overall quality and desirability of the coffee. Understanding each attribute and how to assess it is crucial for effective coffee evaluation.
Aroma/Fragrance: The First Impression
The aroma, or fragrance, of the coffee is the first impression. It provides clues about the coffee’s potential flavor profile and can be a good indicator of its overall quality. Aromas are typically described using descriptive terms that evoke specific scents, such as floral, fruity, nutty, chocolatey, spicy, or earthy. A complex and pleasing aroma is a sign of a high-quality coffee.
Flavor: The Heart of the Coffee
Flavor is arguably the most important attribute of coffee. It refers to the overall taste sensation experienced when the coffee is slurped. The flavor profile can be incredibly diverse, ranging from bright and acidic to sweet and chocolatey to complex and savory. The best coffees exhibit a balance of flavors that are both pleasant and interesting.
Acidity: Brightness and Zing
Acidity is a key component of coffee flavor. It refers to the tartness or brightness of the coffee. A well-balanced acidity can add complexity and vibrancy to the coffee, while a lack of acidity can make the coffee taste flat or dull. Acidity is often described using terms like citric, malic, or phosphoric, depending on the specific type of acid present.
Body: The Mouthfeel
Body refers to the tactile sensation of the coffee in the mouth. It is often described as light, medium, or heavy. A full-bodied coffee will feel rich and coating on the palate, while a light-bodied coffee will feel more delicate and watery. The ideal body will depend on the type of coffee and the desired brewing method.
Aftertaste: The Lingering Impression
Aftertaste is the lingering taste sensation that remains after the coffee has been swallowed. A pleasant and long-lasting aftertaste is a sign of a high-quality coffee. Aftertastes can be described using similar terms to flavors, such as chocolatey, nutty, or fruity.
Balance: Harmony of Flavors
Balance refers to the harmony and integration of all the different attributes of the coffee. A well-balanced coffee will have a harmonious blend of flavor, acidity, body, and aftertaste. No single attribute should dominate the others.
Cleanliness: Absence of Defects
Cleanliness refers to the absence of any off-flavors or taints in the coffee. A clean coffee will taste pure and unadulterated. Defects can be caused by a variety of factors, such as poor processing, storage, or roasting.
Sweetness: A Desirable Quality
Sweetness is a desirable quality in coffee. It can be present in varying degrees, from subtle to pronounced. Sweetness is often associated with high-quality coffees that have been carefully processed.
Scoring Systems: Quantifying Quality
While descriptive evaluations are essential, scoring systems provide a numerical representation of the coffee’s quality, allowing for easier comparison and ranking. Several scoring systems are used in the coffee industry, each with its own criteria and scale.
The Specialty Coffee Association (SCA) Scoring System
The Specialty Coffee Association (SCA) scoring system is the most widely used system in the specialty coffee industry. It assigns a score from 0 to 100 based on the evaluation of various attributes. Coffees that score 80 or above are considered “specialty grade.”
The SCA scoring system evaluates the following attributes: fragrance/aroma, flavor, aftertaste, acidity, body, balance, uniformity, cleanliness, sweetness, and overall. Each attribute is scored on a scale of 0 to 10, with 0 representing a complete absence of the attribute and 10 representing exceptional quality.
The SCA scoring system also includes a defect score, which penalizes coffees for the presence of taints or faults. Taints are minor defects that detract from the coffee’s flavor, while faults are more serious defects that render the coffee undrinkable.
SCA Score Ranges:
* 90-100: Outstanding
* 85-89.99: Excellent
* 80-84.99: Very Good
* Below 80: Not Specialty Grade
Other Scoring Systems
While the SCA scoring system is the most common, other scoring systems are also used in the coffee industry. These systems may vary in their criteria and scale, but they all aim to provide a numerical representation of the coffee’s quality. Some alternative systems include country-specific grading protocols and proprietary systems developed by individual roasters or importers.
Factors Influencing Coffee Quality
Many factors contribute to the overall quality of coffee, from the variety of coffee plant to the processing methods used to the roasting and brewing techniques employed. Understanding these factors is crucial for evaluating coffee effectively and making informed decisions about buying, selling, and roasting coffee.
Origin and Variety
The origin of the coffee beans and the variety of coffee plant play a significant role in the coffee’s flavor profile. Different regions and varieties produce coffees with distinct characteristics. For example, Ethiopian Yirgacheffe coffees are known for their bright acidity and floral aromas, while Sumatran coffees are often characterized by their earthy and full-bodied flavors.
Processing Methods
The processing method used to remove the coffee cherry from the beans also significantly impacts the coffee’s flavor. The most common processing methods are washed, natural, and honey processed. Washed coffees tend to be cleaner and brighter, while natural coffees are often sweeter and more complex. Honey processed coffees fall somewhere in between, offering a balance of sweetness and acidity.
Roasting
Roasting is a critical step in the coffee production process. It transforms the green coffee beans into the aromatic and flavorful beverage we know and love. The roasting process develops the coffee’s flavor, aroma, body, and acidity. A skilled roaster can bring out the best qualities of the coffee, while a poor roasting job can ruin even the highest-quality beans.
Storage and Handling
Proper storage and handling are essential for preserving the quality of coffee. Green coffee beans should be stored in a cool, dry place away from direct sunlight. Roasted coffee beans should be stored in an airtight container to prevent oxidation and loss of flavor. Improper storage can lead to stale or off-flavors in the coffee.
Brewing Methods
The brewing method used to prepare the coffee can also affect its flavor. Different brewing methods extract different compounds from the coffee beans, resulting in variations in flavor, body, and acidity. Factors like water temperature, grind size, and brewing time can all influence the final cup of coffee.
