The democratization of coffee tasting has contributed to a greater appreciation for quality coffee and a deeper understanding of the factors that influence its flavor.

Understanding the Coffee Cupping Protocol

The coffee cupping protocol is a structured method designed to minimize bias and ensure consistent evaluation. While variations may exist depending on the context (e.g., a competition versus a casual tasting), the fundamental principles remain the same. Here’s a breakdown of the key steps involved in a standard coffee cupping session:

Preparation: Setting the Stage for Sensory Exploration

Proper preparation is paramount to a successful coffee cupping experience. This involves selecting appropriate equipment, preparing the coffee samples, and creating a distraction-free environment. Here’s a detailed look at each aspect:

Equipment: You’ll need several essential tools, including:

• Cupping bowls: These are typically made of ceramic or glass and should be of uniform size and shape (usually around 200-250 ml). The consistency helps maintain uniform temperature and extraction.
• Cupping spoons: These are specifically designed for scooping and slurping coffee. They are usually made of stainless steel and have a deep bowl that allows for a good amount of liquid to be sampled.
• Grinder: A burr grinder is essential for achieving a consistent particle size, which is crucial for even extraction. Avoid blade grinders, as they produce inconsistent grinds that can negatively impact the flavor.
• Kettle: A gooseneck kettle allows for precise pouring and control over water temperature.
• Thermometer: Maintaining the correct water temperature (typically between 200-205°F or 93-96°C) is vital for optimal extraction.
• Timer: Accurate timing is crucial for each step of the cupping process.
• Water: Use filtered water that is free of chlorine and other impurities. The quality of the water can significantly impact the taste of the coffee.
• Spittoon: A receptacle for discarding coffee after tasting.
• Cupping form: A standardized form for recording your observations and scores. The SCA cupping form is a widely used example.

Coffee Sample Preparation:

• Roast date: Ideally, the coffee should be roasted within the past few days, as the flavors tend to fade over time.
• Grind size: Grind the coffee coarsely, similar to the consistency of sea salt. The grind should be uniform and free of fines (very small particles).
• Coffee-to-water ratio: A standard ratio is 8.25 grams of coffee per 150 ml of water. This ensures a consistent strength across all samples.
• Multiple samples: Prepare multiple bowls (usually 3-5) of each coffee to ensure consistency and allow for repeated tasting.

Environment:

• Neutral environment: Choose a quiet and well-lit space that is free of strong odors. Avoid distractions such as perfumes, scented candles, or loud noises.
• Adequate lighting: Good lighting is important for visually assessing the coffee’s color and clarity.

The Cupping Process: A Step-by-Step Guide

Once the preparation is complete, you can begin the cupping process. Here’s a detailed breakdown of each step:

1. Dry Aroma (Fragrance):

This is the first sensory assessment and involves evaluating the aroma of the dry, ground coffee. Gently inhale the fragrance from each bowl and try to identify the dominant aromas. Common descriptors include floral, fruity, nutty, chocolatey, spicy, and earthy notes. Note the intensity and complexity of the aroma.

2. Wet Aroma (Aroma):

Pour hot water (between 200-205°F or 93-96°C) over the ground coffee, ensuring that all the grounds are saturated. Allow the coffee to bloom for 3-5 minutes. As the coffee blooms, it releases volatile compounds that create a more complex and intense aroma. Again, carefully inhale the aroma and try to identify the different notes. Compare the wet aroma to the dry aroma and note any changes or new aromas that emerge.

3. Breaking the Crust:

After the blooming period, use a cupping spoon to gently break the crust that has formed on the surface of the coffee. As you break the crust, inhale the aroma again, paying attention to any new or intensified aromas. This step releases additional volatile compounds and provides another opportunity to evaluate the coffee’s aromatic profile.

4. Skimming:

Use two cupping spoons to remove any foam or remaining coffee grounds from the surface of the coffee. This is important for ensuring a clean and unobstructed tasting experience.

5. Tasting (Slurping):

This is the most important step in the cupping process. Use a cupping spoon to scoop up a small amount of coffee and then slurp it forcefully into your mouth. The slurping action helps to aerate the coffee and distribute it evenly across your palate, maximizing the sensory experience. Focus on identifying the different flavors, body, acidity, and aftertaste.

6. Evaluating:

After slurping, take a moment to evaluate the coffee’s characteristics. Consider the following aspects:

• Flavor: The overall taste of the coffee. Identify the specific flavor notes, such as citrus, berry, chocolate, caramel, nutty, or floral.
• Acidity: The brightness or tartness of the coffee. Acidity can be described as bright, lively, sharp, or mellow.
• Body: The weight or texture of the coffee in your mouth. Body can be described as light, medium, heavy, creamy, or syrupy.
• Finish: The lingering taste or sensation after you swallow the coffee. The finish can be long or short, pleasant or unpleasant.
• Balance: How well the different characteristics of the coffee (flavor, acidity, body, and finish) work together. A balanced coffee will have a harmonious and well-integrated flavor profile.
• Sweetness: The perceived sweetness of the coffee, even if no sugar has been added. This is often related to the presence of certain acids and sugars in the coffee.
• Clean Cup: Refers to the absence of any off-flavors or defects in the coffee. A clean cup will be free of any unpleasant or distracting tastes.
• Uniformity: The consistency of the flavor profile across all the cups of the same coffee. Ideally, all the cups should taste the same.

7. Scoring:

Use a cupping form to record your observations and scores for each coffee. The SCA cupping form uses a 100-point scale, with points awarded for each of the characteristics mentioned above. Be as objective as possible and provide detailed notes to support your scores.

Tips for Effective Cupping

• Focus: Concentrate on the sensory experience and avoid distractions.
• Be objective: Try to evaluate the coffee based on its inherent qualities, rather than your personal preferences.
• Be consistent: Use the same cupping protocol and scoring system for all coffees.
• Practice: The more you cup, the better you’ll become at identifying and describing different coffee characteristics.
• Take notes: Detailed notes will help you remember your observations and track your progress.
• Cleanse your palate: Drink water or eat plain crackers between samples to cleanse your palate and prevent flavor carryover.
• Don’t be afraid to experiment: Try different coffees and brewing methods to expand your knowledge and develop your palate.

Factors Influencing Coffee Flavor

The flavor of coffee is influenced by a complex interplay of factors, from the origin of the beans to the way they are roasted and brewed. Understanding these factors can help you appreciate the nuances of different coffees and make informed choices about what you drink.

Origin and Terroir

The origin of the coffee beans is one of the most significant factors influencing their flavor. Different regions are known for producing coffees with distinct characteristics, due to variations in climate, soil, altitude, and coffee varietals. The concept of “terroir,” which refers to the environmental factors that affect a crop’s characteristics, is particularly relevant in coffee. For example:

• Ethiopia: Known for its bright acidity, floral aromas, and fruity flavors.
• Kenya: Known for its complex acidity, black currant notes, and vibrant flavors.
• Colombia: Known for its balanced flavors, medium body, and nutty or caramel notes.
• Sumatra: Known for its earthy notes, full body, and low acidity.

Coffee Varietal

The coffee varietal, or cultivar, also plays a significant role in determining its flavor. Arabica and Robusta are the two main species of coffee beans, with Arabica generally considered to be higher in quality and flavor. Within the Arabica species, there are many different varietals, each with its own unique characteristics. Some common Arabica varietals include:

• Typica: One of the oldest and most widely planted Arabica varietals. Known for its clean, balanced flavors.
• Bourbon: A mutation of Typica. Known for its sweetness, complexity, and good acidity.
• Geisha (or Gesha): Originating from Ethiopia. Known for its floral aromas, delicate body, and tea-like flavors.
• Caturra: A mutation of Bourbon. Known for its high acidity and bright flavors.

Processing Method

The processing method refers to the way the coffee cherries are handled after they are harvested. Different processing methods can significantly impact the coffee’s flavor.

• Washed (Wet) Process: The coffee cherries are pulped, and the beans are fermented to remove the remaining mucilage. This process typically results in coffees with bright acidity, clean flavors, and a lighter body.
• Natural (Dry) Process: The coffee cherries are dried whole, allowing the beans to absorb the sugars and flavors from the fruit. This process often results in coffees with fruity flavors, a heavier body, and lower acidity.
• Honey Process (Pulped Natural): The coffee cherries are pulped, but some of the mucilage is left on the beans during drying. This process can result in coffees with a balance of acidity, sweetness, and body.

Roasting

Roasting is a crucial step in the coffee production process, as it transforms the green coffee beans into the flavorful roasted beans that we know and love. The roast level and profile can significantly impact the coffee’s flavor.

• Light Roast: Retains more of the coffee’s original acidity and flavor characteristics. Often used for specialty coffees.
• Medium Roast: Offers a balance of acidity, body, and flavor. A versatile roast level that is suitable for a variety of brewing methods.
• Dark Roast: Develops more roasty flavors, such as chocolate, caramel, and smoky notes. Often used for espresso blends.

Brewing Method

The brewing method also plays a role in the final flavor of the coffee. Different brewing methods extract different compounds from the coffee grounds, resulting in variations in flavor, body, and acidity.

• Drip Coffee: A common and convenient brewing method that produces a balanced cup of coffee.
• Pour Over: Allows for greater control over the brewing process, resulting in a more nuanced and flavorful cup.
• French Press: Produces a full-bodied cup of coffee with a rich and sediment-heavy texture.
• Espresso: A concentrated brewing method that produces a strong, intense shot of coffee.
