Sensory Bias in Coffee Tasting
How expectation, order, environment, language and personal experience can influence coffee evaluation.
Expectation effects
Knowing a coffee is expensive, unusual or from a famous origin can change expectations before tasting. Blind or partially blind tasting can reduce some of this influence.
Order effects
The coffee tasted immediately before can affect the perception of the next sample. Strong flavours and fatigue can influence later judgements.
Individual differences
People differ in sensory sensitivity, vocabulary, food experience and cultural reference points. Agreement is useful but disagreement is not automatically evidence that one taster is wrong.
Designing better tastings
Consistent preparation, neutral presentation, adequate breaks and clear instructions help make comparisons more useful.
