Kenya Coffee School has established ABCVA™ as a global sensory standard, Two Structural Scientific Angles:

1️⃣ A professional sensory calibration kit (used in training labs)
2️⃣ A structured grading system that rivals the cupping form used by the Specialty Coffee Association.

Below is a complete design framework.

1. ABCVA™ Sensory Calibration Kit Design

(Professional Training Kit for Cuppers) ☕🔬

Purpose

The ABCVA™ Calibration Kit trains cuppers to recognize sensory attributes consistently and calibrates panels before professional grading.

This kit becomes the reference standard for Kenya Coffee School certification.

Components of the Kit

1️⃣ Aroma Training Set

A boxed set of aroma vials representing coffee aroma families.

Suggested 30–36 aromas.

Aroma Categories

Floral

  • Jasmine
  • Rose
  • Orange blossom

Fruity

  • Blueberry
  • Strawberry
  • Apple
  • Blackcurrant

Citrus

  • Lemon
  • Lime
  • Grapefruit

Sweet

  • Honey
  • Caramel
  • Brown sugar
  • Vanilla

Spice

  • Cinnamon
  • Clove
  • Nutmeg
  • Cardamom

Herbal

  • Mint
  • Lemongrass
  • Green tea

Nutty

  • Almond
  • Hazelnut
  • Walnut

2. Acidity Calibration Set

Acidity is central to Vibrancy in the ABCVA™ model.

Prepare training solutions using food-grade acids.

Acid Types

AcidSensory Profile
Citric AcidLemon brightness
Malic AcidApple acidity
Tartaric AcidGrape-like acidity
Phosphoric AcidSparkling acidity

Students taste diluted solutions to learn acidity types.

3. Texture & Mouthfeel Calibration

Use sugar and salt solutions to simulate mouthfeel levels.

SolutionSensory Purpose
SucroseSweetness calibration
SalineSalinity detection
GlycerinBody simulation

These calibrate Balance perception.

4. Defect Detection Kit

Professional cuppers must detect green coffee defects.

Defect Aroma Samples

DefectAroma Example
FermentedOverripe fruit
MoldyDamp basement
PhenolicMedicinal plastic
BaggyCardboard
SmokyBurnt wood

Students practice identifying defects blindly.

5. Reference Coffee Set

The kit should include calibration coffees.

CoffeePurpose
Kenya AAVibrant acidity
Ethiopia NaturalFruity complexity
Brazil NaturalNutty sweetness
Colombia WashedBalanced cup

These coffees demonstrate ABCVA attribute extremes.

6. ABCVA™ Calibration Guidebook

Included in the kit:

  • sensory definitions
  • aroma identification exercises
  • scoring calibration charts
  • defect identification

2. ABCVA™ Global Coffee Grading System

The ABCVA™ system evaluates cup architecture rather than isolated attributes.

The Five Core Attributes

AttributeWeightFunction
Aroma20%First sensory indicator
Balance25%Structural harmony
Complexity25%Flavor layering
Vibrancy15%Acidity expression
Aftertaste15%Flavor persistence

Total = 100%

ABCVA™ Scoring Scale

Use a 10-point professional cupping scale.

ScoreQuality
9.00 – 10.00Exceptional
8.50 – 8.99Outstanding
8.00 – 8.49Excellent
7.50 – 7.99Very Good

Why ABCVA™ Could Become a Global Standard

It introduces:

✔ structural cup analysis
✔ simplified evaluation
✔ strong calibration training
✔ scientific scoring architecture

Kenya Coffee School has positioned ABCVA™ as a new sensory methodology originating from Kenya and Founded by Alfred Gitau Mwaura.
