Typicality of Rioja wines: identification of sensory profiles for the three subregions of DOCa Rioja

Abstract

Within the DOCa Rioja three main production areas are differentiated: Rioja Alta (RA), Rioja Alavesa (RAv) and Rioja Oriental (RO). They are three diverse territories with particular characteristics that are claimed to give rise to differentiated profiles. The present work aims at evaluating the sensory diversity of young commercial red wines in these three subregions. Therefore 30 young red wines (mainly Tempranillo and vintage 2021), ten from each subregion, were sensory described following a non-verbal free sorting task and a verbal free comment task by 32 well-established Rioja winemakers. The sorting task evidenced that the main sensory differences perceived were between Rioja Oriental and Rioja Alta/Rioja Alavesa. These differences were mainly attributed to colour intensity, body/structure and liquorice aroma, which were perceived with higher intensity in wines from Rioja Alta/Rioja Alavesa than in those from Rioja Oriental. The free description task showed shared sensory profiles but also specific sensory profiles for each of the three regions. Rioja Alta and Alavesa display a common sensory profile characterised with high colour intensity and purple-violet hue, high aroma intensity with fresh fruit and lactic aromas and high acidity. Similarly, Rioja Alavesa and Oriental share a prototype of wine described with low colour and medium aromatic intensities, grassy and fresh aroma, and powerful tannin with low acidity. Regarding specific characteristics, Rioja Alta presents a unique and typical profile with high colour intensity, ripe fruit, spicy and balsamic/mint aromas with powerful tannins. Rioja Alavesa´s typical profile is characterised by medium colour intensity, gummy candy, fresh fruit, lactic and floral aroma, with silky, and mellow mouthfeel. The characteristic profile for Rioja Oriental was moderate colour intensity with ruby-garnet hue, dried fruit, jammy fruit, alcohol and spicy aromas and light in mouth. This project is of particular importance since it is the first-time scientific research tries to distinguish between the three subregions of DOCa Rioja and attempts to provide a sensory identity, contributing at the same time to a better understanding of the notion of typicity in wine.

Combined use of leaf removal and natural shading to delay grape ripening in Manto negro (Vitis vinifera L.) under deficit irrigation 

The increasingly frequent heat waves during grape ripening pose challenges for premium wine grape production. This makes the development of irrigation and canopy management techniques of great importance to maximize yield and grape quality. A field experiment was carried out during 2021 and 2022 using Manto negro wine grapes to study the effect of two irrigation strategies and different light exposure levels on grape quality.

Yeast mannoprotein characterization and their effect on Oenococcus oeni and malolactic fermentation

Mannoproteins are released at the end of alcoholic fermentation due to yeast autolysis [1]. It has been described a positive effect of these molecules on lactic acid bacteria growth [2]. The main objective of this work was the characterization of different mannoproteins extracted from active dry yeast (ADY) and the assessment of their effect on Oenococcus oeni and malolactic fermentation (MLF).

Mycorrhizal symbiosis modulates flavonoid and amino acid profiles in grapes of Tempranillo and Cabernet Sauvignon 

Arbuscular mycorrhizal fungi (AMF) symbiosis is probably the most widespread beneficial interaction between plants and microorganisms. AMF has been widely reported to promote grapevine growth, water and nutrient uptake as well as both biotic and abiotic stress tolerance[1]. However, the impact of AMF on grape composition has been less studied. The aim of this work was to evaluate the effects of the association between two commercial grapevine cultivars (Tempranillo and Cabernet Sauvignon grafted onto 110 rootstock) and AMF on the anthocyanin, flavonol and amino acid concentrations and profiles of grapes.

Performance of Selected Uruguayan Native Yeasts for Tannat Wine Production at Pilot Scale

The wine industry is increasing the demand for indigenous yeasts adapted to the terroir to produce unique wines that reflect the distinctive characteristics of each region. In our group, we have identified and characterized 60 native yeast strains isolated from a vineyard in Maldonado-Uruguay, in which three strains stood out: Saccharomyces cerevisiae T193FS, Saturnispora diversa T191FS, and Starmerella bacillaris T193MS. Their oenological potential was evaluated at a semi-pilot scale in Tannat must vinification in the wine cellar to have a more precise and representative evaluation of the final product.

The environmental footprint of selected vineyard management practices: A case study from Logroño (La Rioja) Spain

Viticulture is globally important for socioeconomic and environmental reasons. The EU is globally leading grape and wine production, and Spain is among the top grape and wine producers. As climate change affects viticulture, mitigation and adaptation are crucial for protecting grape production. In this research work, data on viticultural management practices such as soil cultivation, irrigation, energy, machinery, plant protection and the use of fertilizers from vineyards located in Logroño (La Rioja) have been obtained.
