Sensorial characteristic of single variety red wines from four local variants of Tempranillo

Abstract

It is well-known that there is a relationship between the “terroir” and the characteristics of grapes and quality of wines. However, adequate grape variety and other cultural factors should be also taken into account. Among the grape varieties cultivated, large number of local variants names are detected, which usually do reference to the region or zone. Usually vineyards can show some divergences that are correlated with vine adaptation to the medium (soil, climate, topography, etc.). This study was focused on the evaluation of the sensory characteristics of single-variety red wines elaborated with grapes from four different local variants of Tempranillo grapes, one of the most important Spanish red grape varieties. Vineyards were sited on homogenous soil units (Gomez-Miguel and Sotes, 2003) classified as optimal or good. Grapes were harvested in similar ripening stages, and wines were obtained applying the same winemaking processes, which were carried out in the winery of The Oenological Station of Castilla y León.
Obtained wines showed general sensory profiles very similar but some significant differences were found among them. Some aroma components (vegetal and fruity) so as some mouth feel sensations (astringency and green and hard tannins) showed the most notable differences. The effect of microoxygenation treatment of the wines was clearly noted on chromatic, aromatic and mouth feel sensations. Microoxygenated wines were valuated with higher values of colour intensity, violet tones, fruity note, global astringency and hard tannins, and with lower values of dirty, sulphidric and reduction aromas than no microoxygenated ones. After one year of wood aging, differences among microoxygenated wines and control ones were reduced.

Using climate services to project grapevine varietal adequation under climate change – application to cv. Tempranillo in the Douro wine region

Vine growth circumstances are becoming warmer and drier because of climate change. Higher temperatures advance ripening to a point in the season less conducive to the production of fine wine, while drought reduces yields (Van Leeuwen et al., 2019). Several wine-producing regions around the world have already recognized threats to their viticultural viability (Santos et al., 2020). An economical and cost-effective strategy for adaptation is the employment of late-ripening, drought-resistant plant material (varieties, clones, and rootstocks).

Development of bioprospecting tools for oenological applications

Wine is the result of a complex biochemical process. From a microbiological point of view, the grape berry is characterised by a heterogeneous microbiota composed of different microorganisms (yeasts, bacteria and filamentous fungi) which will play a predominant role in the quality of the final product. At this level, yeasts play a predominant role in the chemistry of wine, as they

AIM: Lactiplantibacillus plantarum species is wordwide used as starter for malolactic fermentation [1,2]. For the first time, in the present study, the use of L. plantarum (ML PrimeTM, Lallemand wine) to produce white wines with post-fermentative maceration extended until 60 days has been investigated.

Exploring the potential of Hanseniaspora vineae for quality wines production

Traditionally, non-saccharomyces yeasts were deemed undesirable in winemaking, for this reason, it is a common practice to add sulphites to prevent their proliferation during the initial stages of vinification. However, the current research on yeast diversity has unveiled numerous non-saccharomyces strains possessing advantageous traits that enrich the sensory profile of wines. The genus hanseniaspora is often associated with wine fermentation and is also commonly found on grapes.
