Wine Sensory Quality System™

What sensory evaluation techniques are necessary to identify and measure wine excellence?

To identify wine excellence through sensory analysis, a systematic evaluation of appearance, aroma, flavor, texture, and defects is conducted using trained panels and standardized protocols.

Some of the sensory attributes evaluated

Attribute intensity

Trained panels rate the intensity of specific attributes (such as fruitiness, tannin astringency, acidity, body, oak notes).

Defects & conformity

Panels are trained to detect off-flavors, taints, or process faults like corkiness, oxidation, sulfur, brettanomyces, smoke taint, etc., with clear threshold criteria for acceptability.

Certification standards

Used in national and appellation certification systems to assure wines meet minimum standards and are free from unacceptable defects before market release.

Appearance

Assessed visually for correctness and appeal according to wine type (white, red, rosé).

Aroma

Assessment of primary (fruit, floral), secondary (fermentation), and tertiary (aging) aromas.

Taste & finish

Balanced intensity and texture sensations, body, astringency, warmth, texture, persistence of pleasant, harmonious flavors after swallowing.

Implementation

  • Panels typically consist of at least 4–6 trained tasters.

These methods and criteria allow for a comprehensive sensory identification and grading of wine excellence, supporting effective product evaluation and differentiation.
