blind tasting
- Definition and scope: Blind tasting is a sensory evaluation method in which participants do not know the identity of the samples being evaluated. The aim is to minimize bias based on labeling, price, origin, or color, thereby achieving more objective assessments of aroma, taste, and finish in whisky.
- Sensory evaluation areas: In blind tasting, typically three main dimensions are assessed: aroma (nose), taste (mouth) and finish. Further considerations may include body and mouthfeel, and balance. Notes are recorded for aromas such as fruit, spices, wood, smoke, and vanilla, as well as for taste nuances such as sweetness, acidity, bitterness and intensity.
- Method and environment:
- Samples are placed in covered containers labeled with codes (e.g., 1–6) to conceal identity.
- The order is randomized to avoid systematic bias.
- Glass shape: tulip-shaped whisky glasses are recommended to concentrate the aroma.
- Temperature should be around 15–18 °C.
- The evaluation can be single-blind (tasters do not know the identity of the samples, but the organizer does) or double-blind (neither tasters nor organizers know the identity).
- Evaluation criteria and scoring: For each sample, the aroma is assessed (presence of notes such as fruit, spices, wood, smoke), taste (sweet, salty, bitter nuances, the balance between sweetness and spice), body and texture, finish and length. Many systems use a simple 5-point or 100-point scale, as well as a comment field.
- Bias, sources of error and controls: Color, labels, and pricing can affect the evaluation. Blind protocols, standardized evaluation forms, and use of neutral, non-branded containers help reduce bias. Discussion during the session itself is avoided to preserve objectivity.
- Applications: Blind tasting is used for sensory education, for product development and for competition judging as well as market research and quality control.
