    The Art and Science of Cupping

    Cupping is the standardized method for evaluating coffee quality. For Ethiopian coffees, proper cupping technique is essential to fully appreciate—and accurately assess—these complex origins.

    SCA Cupping Protocol

    Equipment Required

    • Cupping bowls (150-180ml capacity)
    • Cupping spoons (standard depth)
    • Grinder (clean between samples)
    • Kettle with thermometer
    • Timer
    • Cupping forms
    • Rinse water and cups

    Standard Parameters

    ParameterSpecification
    Coffee dose8.25g per 150ml
    Grind sizeSlightly coarser than drip
    Water temperature93°C (200°F)
    Steep time4 minutes
    Total cupsMinimum 5 per sample

    Ethiopian-Specific Considerations

    Roast Profile

    • Light roast preferred: Allows varietal expression
    • Target development: 10-12% weight loss
    • Color: Agtron 65-70 whole bean
    • Rest period: 8-24 hours post-roast

    Common Flavor Descriptors

    Washed Ethiopian

    • Aromatics: Jasmine, bergamot, lemon zest
    • Acidity: Citric, malic, bright
    • Body: Tea-like, delicate
    • Finish: Clean, lingering floral

    Natural Ethiopian

    • Aromatics: Blueberry jam, strawberry, wine
    • Acidity: Soft, fruity
    • Body: Syrupy, full
    • Finish: Sweet, berry-forward

    Cupping Procedure

    Step 1: Fragrance (Dry)

    • Grind samples immediately before cupping
    • Assess dry fragrance within 15 minutes
    • Note initial aromatics and intensity

    Step 2: Crust/Break

    • Pour water at 93°C, saturating all grounds
    • Allow 4-minute steep
    • Break crust by pushing grounds back
    • Inhale deeply at surface level
    • Note aroma evolution

    Step 3: Slurping

    • Begin at approximately 70°C
    • Aspirate coffee across palate
    • Evaluate flavor, acidity, body
    • Take breaks to avoid palate fatigue

    Step 4: Cooling Evaluation

    • Continue cupping as coffee cools
    • Ethiopian coffees often improve cooler
    • Final evaluation around 35-40°C
    • Assess aftertaste and overall impression

    • Grade 2: 80-84 points typical
    • Exceptional lots: 87-90+ achievable

    Common Defects to Identify

    Processing Defects

    • Ferment: Overfermentation in naturals
    • Baggy: Stale, cardboard-like
    • Rio: Medicinal, iodine notes
    • Mold: Musty, damp character

    Green Coffee Defects

    • Quakers: Underdeveloped, peanut-like
    • Faded: Aged, hay-like
    • Past crop: Flat, woody

    Calibration Tips

    For Consistent Evaluation

    1. Cup at the same time daily
    2. Use reference samples for calibration
    3. Cup blind when possible
    4. Take detailed notes
    5. Re-cup questionable samples

    Building Ethiopian Flavor Memory

    • Cup multiple regions side by side
    • Compare processing methods
    • Track scores over seasons
    • Visit origin when possible

    Documentation Best Practices

    Essential Information

    • Sample ID and lot number
    • Roast date and profile
    • Cupping date and time
    • Score and descriptors
    • Overall impression

    For Purchase Decisions

    • Multiple cupping sessions
    • Different roast profiles if uncertain
    • Comparison to reference samples
    • Value assessment vs. price

    Conclusion

    Proper cupping technique reveals the full potential of Ethiopian coffee. Whether evaluating Grade 1 Guji or assessing ECX lots, consistent protocol ensures accurate quality assessment.
