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


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.

Nitrogen isotope ratio (δ15N) as a tool to trace the major nitrogen source in vineyards

Aim: to elucidate if it is possible to detect variations in the source of nitrogen (organic vs. inorganic) measuring nitrogen isotope ratio (δ15N) in berries and to examine the degree of variation occurring for this parameter naturally within a vineyard.

What is the fate of oxygen consumed by red wine? Main processes and reaction products

Oxygen consumed by wine is used to oxidize sulfur dioxide and ethanol to form acetaldehyde wine oxygen consumption rate (OCR) was negatively correlated with the initial acetaldehyde level.

Plant nitrogen assimilation and partitioning as a function of crop load

Aims: The optimization of nitrogen use efficiency (NUE, i.e. uptake, assimilation and partitioning) is a solution towards the sustainable production of premium wines, while reducing fertilization and environmental impact. The influence of crop load on the accumulation of N compounds in fruits is still poorly understood. The present study assesses the impacts of bunch thinning on NUE and the consequences on the free amino N (FAN) profile in fruits.


Marselan wines have an unusual high proportion of seed derived tannins from grapes having high proportions of skins, which are rich in tannins. But the causes behind this characteristic have not yet been identified. In vintage 2023 wines were made at experimental scale (9 kg by experimental unit) from Arinarnoa, Marselan and Tannat Vitis vinifera grape cultivars by traditional maceration, and by techniques aimed to increase the wine content in skin derived tannin: addition of extraction enzymes, addition at vatting of grape-skin enological tannins, or by extended maceration, known to increase the seed derived tannin contents of wines. Macerations were of 7 days, except in the extended macerations that were of 15 days.
