“…Of all of them, methyl jasmonate (MeJ) has been the most studied one. The main effect of MeJ is the improvement of the phenolic composition in several grape varieties (Moro et al, 2020; Portu et al, 2018; Ranjbaran et al, 2022; Sáenz de Urturi et al, 2023). In spite of the good results obtained when MeJ is applied to grapevines, the high cost, low water solubility, low thermal stability and phytotoxicity of MeJ limit its efficient applicability, particularly at high concentrations (Chronopoulou et al, 2019; Hartmond et al, 2000).…”

Grapevine is one of the most important perennial fruit crops worldwide. Historically, vineyards were compatible with soil conservation practices and multitrophic biodiversity, but vineyards are now generally eroded and biologically impoverished, making them more susceptible to pests and diseases. However, the idiosyncrasy of the wine sector places wine growers in a unique position to lead the adoption of a range of sustainable management strategies and, thus, to pioneer a wider transformation of the agricultural sector. In this article, we provide an overview of nature‐based management strategies that may be used for the regeneration of the functioning and biodiversity of vineyards and that may also lead to improved plant nutrition, grape berry quality and the suppression of pathogens and pests. These strategies include the use of microbial and nonmicrobial biostimulants, fertilization with organic amendments as well as foliar fertilization with nature‐based products, the use of cover crops and the reintegration of livestock in vineyards, especially sheep. We will also pay special attention to the implementation of circular economy in the vineyard in relation to the previously mentioned management strategies and will also discuss the importance of considering all these aspects from a holistic and integrative perspective, rather than taking them into account as single factors. Assuming the integral role of soils in the functioning of agroecosystems, soils will be considered transversally across all sections. Finally, we will argue that the time is now ripe for innovation from the public and private sectors to contribute to the sustainable management of vineyards while maintaining, or even improving, the profit margin for farmers and winemakers.

“…All of these studies have been carried out with red grape varieties. There are only two works where foliar treatment with MeJ has been performed in white varieties, focused on the effect on the terpene content in grapes [ 16 ] and in a white table grape variety, in which the influence of MeJ on phenolic composition was studied [ 17 ]. MeJ foliar application is an interesting and easy viticultural practice to improve the grape’s aromatic, phenolic and nitrogen composition.…”

Methyl jasmonate (MeJ) is an elicitor that, when applied in the vineyard, can improve grape quality. There are several studies about the MeJ influence on red grape varieties; however, to our knowledge, there is little information about white grape varieties, specifically Tempranillo Blanco. Therefore, the aim of this work is to evaluate the effect of MeJ foliar treatments, carried out at veraison and post-veraison, on the aromatic, phenolic and nitrogen composition of Tempranillo Blanco grapes. The results showed that grape volatile compounds content increased after MeJ application, especially terpenoids, C13 norisoprenoids, benzenoids and alcohols, and, in general, mainly at post-veraison. Regarding phenolic and nitrogen compounds, their concentrations were enhanced after MeJ treatments, regardless of application time. Consequently, MeJ treatment improved grape volatile, phenolic and nitrogen composition, particularly when this elicitor was applied post-veraison. Therefore, this is a good and easy tool to modulate white grape quality.
