Coffee Tasting MOC¶

Coffee tasting encompasses the structured evaluation of brewed coffee through the human senses — assessing aroma, flavour, acidity, body, sweetness, aftertaste, and balance to describe and score cup quality. The SCA (Specialty Coffee Association) cupping protocol is the industry standard for this practice, providing a reproducible framework used by green coffee buyers, roasters, competition judges, and quality control specialists worldwide. This MOC covers the full range of tasting and sensory evaluation: the mechanics of cupping, the primary cup attributes and their scoring, the descriptor language used to communicate what is in the cup, and the skills required to evaluate coffee consistently and accurately.

Deep Dives — Coffee Tasting Overview¶

Article	What it covers
Cupping	SCA-standardised protocol for brewing and evaluating coffee in an open cup
100-Point Scale	Industry-standard scoring framework designating 80+ points as specialty grade
Cup Profile	Structured sensory description communicating a coffee's full aromatic and flavour character
Blind_Tasting	Evaluating coffee without identity information to eliminate cognitive bias
Calibration_Sessions	Structured panel tastings to align evaluator standards and scoring consistency
Acidity	Bright, organic-acid-driven taste sensation and primary positive cup attribute
Acidity_Scoring	SCA cupping form method for evaluating acidity quality and intensity
Aroma	Volatile compound-driven aromatic character assessed before and during tasting
Aroma Identification	Trained skill of recognising and naming coffee's aromatic compounds
Aroma cup	Standardised vessel for isolating and assessing coffee aroma
Aftertaste	Flavours and sensations persisting in the mouth after swallowing
Aftertaste_Evolution	How flavour character develops and changes in the seconds following swallowing
Aftertaste_Scoring	SCA method for evaluating length and quality of the finish
Balance	Harmony and integration across all primary cup attributes
Balance_Scoring	SCA cupping form method for scoring overall attribute integration
Bitterness	Basic taste that contributes depth and complexity when balanced appropriately
Body	Tactile weight, texture, and physical presence of coffee in the mouth
Body Scoring	SCA cupping form method for evaluating tactile weight and viscosity
Brightness	Positive, lively acidity descriptor indicating vibrant, energising cup character
Clean_Cup_Scoring	Binary defect-detection attribute on the SCA cupping form
Astringency	Dry, puckering mouthfeel sensation from polyphenol–protein interaction
Buttery	Smooth, rich, creamy mouthfeel descriptor associated with high lipid content
Watery	Thin, low-body defect indicating under-extraction or high brew ratio
Winey	Fermented red-fruit character associated with natural processing and anaerobic fermentation
Ashy	Dry, charred aroma and flavour defect associated with over-roasting
Burnt	Aggressive charred defect caused by excessive heat or scorching during roasting
Woody	Dry timber or cardboard defect associated with aged or past-crop green coffee
SCA Flavour Wheel	Visual reference organising coffee's sensory descriptors into a hierarchical structure
SCA Sensory Skills	SCA certificate programme covering sensory evaluation at Foundation, Intermediate, and Professional levels
Sensory Science	Systematic study of human taste and smell applied to coffee evaluation methodology
Flavour Memory Pt1	Building and developing a personal sensory vocabulary through deliberate exposure
Flavour Memory Pt 2	Advanced calibration and inter-rater reliability for professional sensory evaluation
Age_and_Taste	Effects of age on taste receptor sensitivity and implications for sensory panel management
Ambient_Odours	How background smells in the evaluation environment interfere with accurate tasting
Chlorogenic Acids	Key phenolic compounds that contribute acidity, bitterness, and astringency to the cup
ANOVA	Statistical method for comparing sensory panel results across multiple tasting groups
AI_Sensory_Prediction	Machine learning models that predict sensory attributes from physical or chemical data
