An overview of wine sensory characterization: from classical descriptive analysis to the emergence of novel profiling techniques

Abstract

The wine industry requires coexistence between tradition and innovation to meet consumers’ preferences. Sensory science allows the objective quantification of consumers’ understanding of a product and subjective feedback of consumer’s perception through acceptance or rejection of stimulus or even describing emotions evoked [1]. To measure sensations, emotions and liking, and their dynamics over time, time-intensity methods are crucial tools with growing interest in sensory science [2].

AIM: This research aimed to give a big picture of the latest investigation about sensory methods and their variations, and the successful application of sensory devices and immersive contexts in wine evaluation.

METHODS: An overview of all the recent findings in sensory science methodologies, including sensory descriptive tests (quantitative descriptive analysis (ADQ), flash profiling, projective mapping and napping, check-all-that-apply (CATA), open-ended questions, preferred attribute elicitation method, polarised sensory positioning, free –choice profiling, sorting) [3], sensory discriminative tests (triangle test, tetrad test, duo-trio test, paired comparison, intensity scales, forced-choice tests) [4], sensory hedonic tests (hedonic methods, consumers’ preference, and emotions), time-intensity methods (dual-attribute time-intensity, multiple-attribute time-intensity, temporal dominance of sensations), instrumental sensory devices and immersive techniques (e-nose, e-tongue, virtual reality, gaming) and sensory data treatment are reviewed.

RESULTS: This study is the first attempt to characterize sensory methods and techniques, from classical descriptive analysis to the emergence of novel profiling techniques, comparing the different approaches and predicting some future research on this topic.

CONCLUSIONS:

The characterization of sensory methods and techniques have been investigated in the literature. However, there is a limited articulation between descriptive, discriminative, hedonic tests and time-intensity methods as well as instrumental sensory devices and immersive techniques. Furthermore, statistical techniques in sensory science play a crucial role and increasingly allow a more precise sensory data analysis and more adapted to a complex product such as wine.

Amyndeon‐naoussa: the two faces of Xinomavro

Xinomavro is the most important indigenous red wine variety grown in Northern Greece. It participates in the production of several PGI wines in Macedonia while from 100% Xinomavro the PDO “Amyndeon” and “Naoussa” are produced. The viticultural area of Amyndeon lies in a plateau of 550 ‐700 m of altitude, in a semi‐continental climate with mostly deep sandy loamy soils derived from limestone and marl bedrocks while in Naoussa, Xinomavro is grown in a Mediterranean climate on more heavy textured soils, sandy clay loam to clay, derived from ophiolithic, limestone and marl bedrocks, in an altitude which varies from 150 to 400 m. Different soil, climate and viticultural technique interactions, result in great variability with respect to morphological, ampelographical and physiological characters of Xinomavro as well as in the characteristics of the wines produced.

Function, barriers, and the environmental benefits of reuse bottle system for wine

With 0.3 to 0.7 kg CO2eq per 0.75 L wine, the glass bottle is the main contributor to the carbon footprint of a bottle of wine.

Impact of mycorrhizal inoculation of ‘Monastrell’ grapevines grafted onto different conventional vs. newly breed rootstocks

Grafting Vitis vinifera L. (wine traditional cultivars) onto North American grapevine species or hybrids is a common practice in viticulture given their tolerance against phylloxera (Daktulosphaira vitifoliae). However, rootstock genetic background affects the response of grapevines to environmental stresses and their ability for establishing a symbiotic relationship with the microbial communities, and more specifically with arbuscular mycorrhizal fungi (AMF).
The aim of this study was to evaluate Monastrell variety (clone ENTAV 369) grafted onto three rootstocks (140Ru, 110R and RG8) characterized by a different genetic background, in combination with AMF inoculation (Rhizophagus irregularis) vs. a non-inoculated control with regards to vegetative growth, leaf gas exchange parameters, and mycorrhization.

Lactic acid bacteria: A possible aid to the remediation of smoke taint?

With climate change, the occurrence of wildfires has increased in several viticultural regions of the world. Subsequently, smoke taint has become a major issue, threatening the sustainability of the wine industry.

Impact and comprehension of nitrogen and lipid nutrition on the production of fermentative aromas with different S. Cerevisiae yeasts used for spirits

In the Cognac appellation, the production of white wines is almost exclusively dedicated to elaborate Charentaise eaux-de-vie. In this sense, the quality of Cognac eaux-de-vie intrinsically depends on the quality of the base wines subjected to the distillation stage. In this context, the production of these base wines differs from those of classic white wines to release particular organoleptic properties during the distillation stage.
