Step-by-Step Guide to Coffee Cupping

Follow these steps to conduct a professional coffee cupping session:

1. Preparation

• Environment: Choose a quiet, well-lit space free from distractions and strong odors.
• Coffee Samples: Roast the coffee samples within 24 hours of cupping, ideally to a light to medium roast level. Ensure even roasting across all samples. Allow the coffee to rest for at least 8 hours before cupping.
• Grinding: Grind each coffee sample coarsely and uniformly, ideally within 15 minutes of brewing.
• Dosage: Use a consistent coffee-to-water ratio. A common ratio is 8.25 grams of ground coffee per 150ml of water (SCA standard).
• Arrangement: Arrange the cupping bowls in a row or grid, with each sample clearly labeled (e.g., sample A, sample B, etc.).

2. Dry Aroma

• Evaluation: Gently sniff the dry grounds in each cup and note the aromas you perceive. Consider using a coffee aroma wheel for reference.
• Record: Document your observations on the cupping form. Describe the intensity and characteristics of the aromas (e.g., floral, fruity, nutty, spicy).
• Purpose: The dry aroma provides the first impression of the coffee's potential.

3. Wet Aroma (Breaking the Crust)

• Pouring: Pour the hot water over the coffee grounds, ensuring complete saturation. Start the timer immediately.
• Blooming: Allow the coffee to bloom for 4 minutes. During this time, the coffee releases carbon dioxide, creating a foamy layer called the "bloom."
• Breaking the Crust: At 4 minutes, use a cupping spoon to gently break the crust by pushing the grounds back and releasing the trapped aromas.
• Evaluation: Immediately after breaking the crust, sniff the wet aroma and note your observations. Compare the wet aroma to the dry aroma.
• Skimming: Use two spoons to skim off any remaining foam and grounds from the surface of each cup.

4. Tasting

• Cooling: Allow the coffee to cool slightly (ideally to around 160°F/71°C) before tasting.
• Slurping: Use a cupping spoon to slurp the coffee vigorously. This aerates the coffee, allowing it to spread across your palate and maximize flavor perception.
• Evaluation: Pay attention to the following characteristics:
  • Acidity: The brightness or tartness of the coffee.
  • Body: The weight or mouthfeel of the coffee.
  • Flavor: The specific tastes and aromas present in the coffee.
  • Finish: The lingering aftertaste of the coffee.
  • Balance: The harmony and complexity of the various characteristics.
  • Sweetness: The presence of sugar-like flavors.
  • Clean Cup: The absence of off-flavors or defects.
• Record: Document your observations on the cupping form, assigning scores based on your evaluation.
• Repeat: Taste each sample multiple times as it cools to observe how the flavors evolve.

5. Scoring and Analysis

• SCA Cupping Form: The Specialty Coffee Association (SCA) cupping form is a widely used tool for evaluating coffee. It includes various attributes, such as aroma, flavor, acidity, body, balance, sweetness, clean cup, and overall impression.
• Scoring Scale: The SCA uses a 100-point scale, where:
  • 80-84.99: Very Good
  • 85-89.99: Excellent
  • 90-100: Outstanding
• Defects: Identify any defects present in the coffee (e.g., sour, fermented, moldy). Deduct points accordingly.
• Analysis: Analyze your scores and notes to identify the strengths and weaknesses of each coffee sample. Compare the samples to each other and to your reference standards.

Developing Your Sensory Skills

Improving your sensory skills is crucial for becoming a proficient coffee cupper. Here are some tips:

• Practice Regularly: Cupping regularly is the best way to develop your palate and improve your ability to identify and describe flavors.
• Blind Tasting: Conduct blind tastings to eliminate bias and focus on your sensory perception.
• Aroma Training: Use aroma kits or essential oils to train your nose to recognize different aromas.
• Flavor Standards: Create flavor standards by dissolving specific compounds in water to represent different tastes (e.g., citric acid for acidity, sucrose for sweetness).
• Expand Your Palate: Try a wide variety of foods and drinks to broaden your flavor vocabulary.
• Join Cupping Groups: Participate in cupping groups or workshops to learn from experienced cuppers and share your observations.

Understanding Coffee Defects

Identifying coffee defects is an essential part of cupping. Defects can arise from various factors, including poor cultivation practices, improper processing, or inadequate storage. Common coffee defects include:

• Sour: A vinegary or acidic taste, often caused by fermentation.
• Fermented: A yeasty or alcoholic taste, also caused by fermentation.
• Moldy: A musty or mildewy taste, indicating the presence of mold.
• Earthy: A dirt-like taste, often caused by contact with the ground.
• Potato Defect: A raw potato-like taste, caused by a specific bacteria. More common in East African coffees.
• Rubbery: A tire-like taste, often associated with over-roasted coffee.
• Grassy/Hay-like: Taste of dried grass or hay, usually from under-ripe or improperly dried coffees.

Being able to identify and describe these defects is crucial for quality control and ensuring that only high-quality coffee reaches consumers.
