Barrels ad-hoc: Spanish oak wood classification by NIRs 

Abstract

The wooden barrel is a key factor in enology, since wine chemical composition and sensory properties changes significantly in contact with the barrel[1]. Today’s highly competitive market constantly demands new differentiated products and wineries search innovations continuously.

Wood selection is crucial: barrels stability to keep constant their contribution and the result on products, and additional and differentiated wood contributions to impact their new products. Oak wood selection has traditionally been carried out using parameters such as specie, location and grain, however, it goes one step further nowadays. Large cooperage work with non-destructive techniques that allow classifying oak wood quickly and easily according to their organoleptic contribution[2].

CETEMAS studies Spanish origins oak (Q. petreae/robur) wood for cooperage. This is highly regarded by leading beverages manufacturer (wineries and whiskey distilleries). NIROB project led us to study the species, location and grain impact on the total phenol wood content, ellagitannin and volatile compounds profile, as well as the wood NIRs analysis implementation. After this study, it was concluded to modify the French grain classification scale for Spanish Quercus. Moreover, the first total phenol content prediction models were developed and applied on staves selection for wine barrels destined to a winery from PDO Vino de Cangas, with really good results.

During running NIRCHEM project, national and international oak are studied comparatively, improving the NIRs phenol content models and developing new ones to predict key compounds content for winemaker’s interest. The different origins oak chemical composition evolution is also studied depending on the seasoning and toasting.

Our goal is the wood knowledge before its selection, to choose the wood that best suits the characteristics sought by the wineries, offering a tool that allows this selection, enhancing and promoting, at the same time, the use of the country’s oak and its proper forest management.

Phenolic composition profile of cv. Tempranillo wines obtained from severe shoot pruning vines under semiarid conditions

One of the limitations of vineyards in warm areas is the loss of wine quality due to higher temperatures during the grape ripening period. In order to adapt the vineyards to these new climatic conditions, a possible solution is to delay the ripening process of the grapes towards periods with milder temperatures, by means of management practices and thus improve the quality of the fruit and the wine produced. The technique of severe shoot pruning (SSP) has proven useful in achieving this objective.

Volatile composition of Cabernet Sauvignon wines from Argentina, Portugal and Spain

Cabernet Sauvignon is one of the most cultivated grape varieties worldwide being grown in different environmental conditions due to its excellent adaptability. Volatile compounds deeply contribute to the sensory properties of wines therefore to wine quality. The aim of this work was to compare the aroma profile of Cabernet Sauvignon wines from different geographical areas and climatic conditions, namely from Argentina, Portugal and Spain, from the vintage 2022. In addition, the volatile composition of the Cabernet Sauvignon Portuguese wines from three vintages was evaluated.

Acceptability of canned wines: effect of the level of involvement of consumers and type of wine

In recent years there has been a growing demand for alternative packaging designs in the food industry focused on diminishing the carbon footprint. Despite the environmental advantages of cans versus bottles, the traditional environment of wine has hindered the establishment of less contaminant containers. In this context, the objective of this study was to understand and generate knowledge about consumers´ perception of canned wines in comparison to bottled wines.

The combined use of Lachancea thermotolerans and lactic bacteria in wine technology

The production of most red wines that are sold involves an alcoholic fermentation carried out by yeasts of the Saccharomyces genus, and a subsequent fermentation carried out by lactic bacteria of the Oenococus oeni species after the first one is fully completed. However, the traditional process can face complications, which can be more likely in grape juices with high levels of sugar and pH. Because of climate change, these situations are more frequent in the wine industry. The main hazards in those scenarios are halts or delays in the alcoholic fermentation or the growth of unwanted bacteria while the alcoholic fermentation is not done yet and the wine still has residual sugars.

Can soil nitrate explain polyphenol and anthocyanin content in vineyard with similar available soil water regime? 

Nitrogen (N) is quite important nutrient in grapevine development and must quality, but under Mediterranean climatic conditions, available soil water (ASW) during grapevine development can also influence vigour and must quality. The aim was to determine the influence of soil nitrate (NO3-) availability on N foliar, yield, and must quality in vineyards with similar available water holding capacity (AWC). For this purpose, four cv. Tempranillo (Vitis vinifera L.) vineyards were selected. All of them are placed in Uruñuela municipality (La Rioja, Spain), separated less than 2.5 km and in a slope <1 %, in soils with similar soil chemistry properties and with similar rooting depth (ranging between 105 cm and 110 cm).
