Popularizing wine tasting evaluation: an adaptation of mouthfeel terminology

Abstract

Wine sensory analysis traditionally relies on complex terminology. This can be challenging to non-expert consumers, particularly regarding mouthfeel sensations. Despite the importance of the latter in determining wine quality and typicity, they lack standardized classification. In this study, we developed and validated a simplified framework for wine taste evaluation that is accessible to consumers with limited tasting experience. The Delphi technique was applied across multiple rounds with a panel of 18 wine experts, primarily sommeliers with experience of diverse consumer profiles. Through an iterative process, attributes were selected from the existing literature and systematically evaluated for relevance, clarity, and accessibility. The validated framework comprises four dimensions: basic tastes (sweetness, acidity, bitterness, salinity, fruitiness); astringency (hardness, dryness, texture); tactile sensations (tingling, warmth, body); and overall evaluation (complexity, balance, taste persistence, alcohol perception). Each attribute includes accessible descriptions and measurement scales anchored with familiar food references to support comparative cognitive processes. All proposed attributes achieved over 85% expert consensus. This framework provides a practical tool that bridges technical wine terminology and everyday consumer language to facilitate communication between industry professionals and consumers. Furthermore, it enables more reliable sensory evaluations in future research and can potentially be extended to other beverages.
