Coffee Acidity as a Sensory Attribute
Understand acidity, sourness, intensity, quality and balance in coffee tasting.
Acidity is not simply sourness
In coffee, acidity can describe a lively sensory quality associated with organic acids and other compounds. Sourness is a taste sensation and can be pleasant or unpleasant depending on context.
Intensity and character
Tasters may distinguish how intense acidity feels from what kind of acidity they perceive. Citrus-like, malic or wine-like comparisons describe character rather than a laboratory measurement.
Roast and extraction
Roasting changes the acid profile, while brewing determines which compounds are extracted and at what concentration. Perceived acidity therefore depends on both coffee and preparation.
Balance matters
Acidity interacts with sweetness, bitterness, body and aroma. A high-acidity coffee is not inherently defective or superior.
