A Coffee Cupping Lab for ABCVA™ Sensory Training is designed as a scientific tasting environment where students learn to evaluate coffee using the Aroma, Balance, Complexity, Vibrancy, and Aftertaste (ABCVA™) framework. The goal is clarity, consistency, and sensory focus. ☕🔬

1. Layout of an ABCVA™ Cupping Lab

The lab has one central cupping table where all participants evaluate a variety of coffees.

Layout

Central Cupping Table

  • Large rectangular wooden table
  • Capacity: 6–12 cuppers
  • Each coffee sample placed in a straight line

Side Stations

1️⃣ Grinding Station

  • Coffee grinder
  • sample trays
  • weighing scale

2️⃣ Hot Water Station

  • Electric kettles
  • temperature control (92–96°C)

3️⃣ Spitting & Rinse Station

  • spittoons
  • rinse cups
  • clean water

4️⃣ Instructor Station

  • ABCVA™ scoring board
  • demonstration cups

2. ABCVA™ Cupping Table Setup

Each coffee sample has 5 cups to ensure consistency.

Example:

Coffee SampleCups
Sample A5 cups
Sample B5 cups
Sample C5 cups

This helps detect defects or inconsistencies.

Per Cupping Position

Each student should have:

  • Cupping spoon
  • ABCVA™ scoring sheet
  • glass rinse cup
  • water glass
  • spit cup
  • pen

3. Equipment Required for ABCVA™ Lab

Essential tools for a Kenya Coffee School sensory lab:

EquipmentQuantity
Cupping bowls (200ml)30–40
Cupping spoons12
Precision scale2
Coffee grinders2
Electric kettles3
Thermometer2
Spittoons6
Timer2

Recommended cupping ratio:

8.25g coffee : 150ml water or 12g coffee : 200ml water

4. ABCVA™ Evaluation Flow

Students follow a structured sensory process.

Step 1 – Fragrance (Dry Aroma)

Smell freshly ground coffee.

Evaluate:

  • Floral
  • Fruity
  • Nutty
  • Spicy

Score under Aroma.

Step 2 – Wet Aroma

Hot water added.

Break the crust after 4 minutes.

Release aromatic compounds.

Score Aroma intensity & quality.

Step 3 – Flavor Evaluation

Start tasting at 8–10 minutes.

Evaluate:

  • Balance – harmony of flavors
  • Complexity – layers of flavor
  • Vibrancy – brightness / acidity
  • Aftertaste – persistence and sweetness

5. ABCVA™ Score Sheet Structure

Example scoring:

AttributeScore
Aroma8.25
Balance8.00
Complexity8.25
Vibrancy8.50
Aftertaste8.00

ABCVA™ Average = 8.20

This reflects the architectural structure of the cup.

6. Sensory Training Exercises

To train professional cuppers, include:

Aroma Training

We Use jars containing:

  • citrus peel
  • cocoa
  • roasted nuts
  • flowers
  • spices

Students identify aromas blindly.

Flavor Calibration

Serve coffees with:

  • high acidity
  • high sweetness
  • high body

Students learn flavor differentiation.

Defect Detection

Use defective coffees:

  • phenolic
  • fermented
  • moldy
  • baggy

Students identify faults.

7. Ideal Environment for the Lab

Our KCS cupping room has:

  • Neutral wall colors
  • Bright white lighting
  • No perfumes or strong smells
  • Quiet environment
  • Good ventilation

Temperature:

20–25°C

8. ABCVA™ Training Programs (Kenya Coffee School)

KCS cupping lab supports the following courses and trainings:

1 Day Training

  • Introduction to ABCVA™

3 Day Training

  • Professional cupping
  • sensory calibration

5 Day Certification
