Response of red grape varieties irrigated during the summer to water availability at the end of winter in four Spanish wine-growing regions: berry phenolic composition

Abstract

Water availability is the most limiting factor for vineyard productivity under Mediterranean conditions. Due to the effects caused by the current climate change, wine-growing regions may face serious soil moisture conservation problems, due to the lower water retention capacity of the soil and higher soil irradiation. The aim of this work was to evaluate the effects of soil recharge irrigation in pre-sprouting and summer irrigation every week (30 % ETo) from the pea size state until the end of ripening (RP) compared to exclusively summer irrigation every week (R) in the same way that RP, on berry phenolic composition at harvest. The experiment was carried out during two consecutive seasons (2021 and 2022), in vineyards of Garnacha Tinta (in Badajoz), Tempranillo (in Valladolid), Syrah (in Albacete) and Mencía (in Lugo). Polyphenolic substances were extracted from grapes and then identified and quantified by high performance liquid chromatography. Compounds grouped into anthocyanins and non-anthocyanins were analyzed. In 2021, pre-sprouting irrigation tended to cause a decrease in the concentration of both anthocyanin and non-anthocyanin compounds, although this was only significant in the case of Syrah flavanols compounds. In 2022, the effect of soil water recharge was more noticeable. In relation to anthocyanin compounds, RP significantly reduced the concentration of monoglucoside, acetylated and coumarilated anthocyanins in Tempranillo, as well as the values of delphinidin, petunidin, peonidin and malvidin derivatives, while in the rest of the varieties the values remained unaffected. The RP treatment, compared to R, tended to increase the concentration values of flavonols and phenolic acids in Tempranillo and decrease that of flavonols in Syrah. The effect of pre-sprouting recharge irrigation was highly dependent on the year and the characteristics of each vineyard.

The 1000 grapevine genomes project: Cataloguing Australia’s grapevine germplasm

Grapevine cultivars can be unequivocally typed by both physical differences (ampelography) and genetic tests. However due to their very similar characteristics, the identification of clones within a cultivar relies on the accurate tracing of supply records to the point of origin. Such records are not always available or reliable, particularly for older accessions. Whole genome sequencing (WGS) provides the most highly detailed methodology for defining grapevine cultivars and more importantly, this can be extended to differentiating clones within those cultivars.

Can yeast cells sense other yeasts beyond competition interactions?

The utilization of non-Saccharomyces yeasts in the wine industry has increased significantly in recent years. Alternative species need commonly be employed in combination with Saccharomyces cerevisiae to avoid stuck fermentation, or microbial spoilage. The employment of more than one yeast starter can lead to interactions between different species with an impact on the outcome of wine fermentation. Previous studies[1] demonstrated that S. cerevisiae elicits transcriptional responses with both shared and species-specific features in co-culture with other yeast species.

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

Grape and wine phenolic compounds have been shown to be highly related to both wine quality (color, flavor, and taste) and health-promoting properties (antioxidant and cardioprotective, among others). The aim of this work was to evaluate and compare the phenolic contents of Cabernet Sauvignon wines from different geographical areas and climatic conditions, namely from Argentina, Portugal and Spain vintage 2022. In addition, the phenolic profiles of the Portuguese wines from three vintages (2020, 2021, 2022) was compared.

Foliar application of urea improved the nitrogen composition of Chenin grapes

The nitrogen composition of the grapes directly affects the developments of alcoholic fermentation and influences the final aromatic composition of the wines. The aim of this study was to determine the effect and efficiency of foliar applications of urea on the nitrogen composition of grapes. This study was carried out during 2023 vintage and in the Chenin vineyard located in Estacion Experimental Mendoza (Argentina). Three urea concentrations 3, 6 and 9 Kg N/ha (C1, C2, and C3, respectively) and control (T) were applied in this vineyard at veraison.
