HRATA : A new sensory methodology using advantage of wine aromatic wheels

Abstract

Wine is an intrinsically complex aromatic product. To formalize this aromatic diversity and the hierarchical structure of the aromas, it is common to present them in the form of a wheel of aromas. These are used for learning and communication purposes but never for the acquisition of sensory characteristics.

The HRATA (Hierarchical Rate All That Apply) methodology proposes to combine the benefits of methodologies traditionally used in sensory evaluation. It proposes both 1°) a complete characterization of the aromas based on a RATA approach that gives tasters a strong freedom in the evaluation of an exhaustive list of attributes and 2°) a hierarchical presentation of attributes that allows tasters to position more or less accurately (family, category or term) according to their perceptions. It facilitates also data acquisition in a professional context without previous common training. Coupled with a computerized user-friendly interface in the form of an interactive aroma wheel, tasters can easily choose and score as many attributes as necessary with different levels of precision if they wish.

This original methodology was tested with 6 wines of Chenin grape variety from the Loire Valley and using the wheels of the Chenin aromas proposed by WOSA. Twenty-four tasters characterized each wine twice with the sole instruction to score as many attributes as necessary on the wheel. Several statistical strategies were compared to analyze this original dataset and to improve the data interpretation and presentation. Some technical issues will be also discussed.

This methodology would be very relevant for exploring the relationships between sensory and physico-chemical characteristics or for studying some sensory concepts such as the typicity or complexity of wines.

Viticultura protegida: uso de mallas sombreadoras fotoselectivas como una herramienta para enfrentar la crisis climática en uva de mesa en el norte de Chile

The production of table grapes in Chile is of great importance, being one of the main established fruit crops with over 43,000 hectares distributed across a diverse climate range, from the southern limit of the Atacama desert to the mediterranean zone. Chile is also one of the leading exporters of table grapes. producers must confront the challenges posed by the climate crisis, such as decreased rainfall, increased heatwaves, and extreme temperature events during the growing season, mainly associated with desertification in northern Chile (Atacama and Coquimbo regions).

Volatile compounds production during ripening of cv. “Sangiovese” grapes from different terroir

“Sangiovese” (Vitis vinifera L. sativa cv. Sangiovese) is the main grape variety to be established in Italy, being the only country in Europe where this grape is commonly found.

Towards 2D mapping of gaseous ethanol in the headspace of wine glasses by infrared laser spectrometry

Under standard wine tasting conditions, volatile organic compounds (VOCs) responsible for the wine’s bouquet progressively invade the chemical space perceived by the consumer in the glass headspace.

Developmental and genetic mechanisms underlying seedlessness in grapevine somatic variants

Seedless table grapes are greatly appreciated for fresh and dry consumption. There is also some interest in seedless winegrapes, because the combination of lower fruit set, smaller berries with higher skin/pulp ratio and looser bunches with the absence of seeds in crushed berries, a possible source of astringent tannins, might also have favorable effects on wine quality.

Do natural wines differ from conventionally-produced wines?

In recent years, consumer awareness for consuming healthy and environmental sustainability products has considerably increased [1]. In an ever-changing and highly competitive environment such as the wine sector, production of wines without sulfites, or biodynamic, organic or vegan wines, has experienced an important increase to meet the new needs of consumers [2,3]. Beyond these categories of regulated products, a new concept has emerged: natural wines (NW), for which there is not an established definition or legal regulation. Rather, producers have a personal idea of naturalness under the premise of applying minimal intervention from grape to wine production [4]. In this context, it is hypothesized that self-defined natural wines are different from conventional wines (CW) in their sensory and chemical profile. The predicament of natural wine is based on anecdotic declarations and assumes that minimal intervention guarantees the production of wines with organoleptic properties able to express the “terroir” and thus promote wine diversity, plurality and sensory typicity against the risk of standardization of CW.
