“…The absence of significant differences regarding the remaining parameters is in contrast to the study conducted by Ancín-Azpilicueta et al (2013). The latter study showed that foliar application of 2 kg N/ha of urea in a Tempranillo vineyard led to an increase in pH and a reduction of alcoholic strength and total acidity in wine that were even more significant when the dose of urea was greater (4 kg N/ha).…”

“…For instance, Fernández et al (2013) detailed some of them, including plant species, leaf cuticular composition, plant phenology, environmental aspects, or phloem mobility. Research in viticulture has shown that foliar application of urea may modify the wine aroma profile (Ancín-Azpilicueta, Nieto-Rojo, & Gómez-Cordón, 2013) or improve must nitrogen composition (Garde-Cerdán et al, 2014). In the latter work, the application of phenylalanine led to a similar enhancement of must nitrogen composition in comparison with urea application.…”

“…reported that these treatments applied to grapevines allowed ethyl hexanoate, ethyl octanoate, and ethyl decanoate content in wines to increase. Ancín‐Azpilicueta et al . showed that the total concentration of higher alcohols in wines decreased with the application of urea in the vineyard, whereas the concentrations of ethyl hexanoate, ethyl octanoate, and ethyl decanoate were highest in the wine obtained from grapevines treated with 4 kg N ha −1 of urea.…”

Resurgence of minority and autochthonous grapevine varieties in South America: a review of their oenological potential

In contrast with the general trend of producing wine from the most famous grapevine varieties, associated with the French paradigm, such as Cabernet‐Sauvignon, Merlot, Pinot Noir, Syrah, Sauvignon Blanc, and Chardonnay, there is a tendency to revalorize and preserve minority or autochthonous grapevine varieties worldwide. The South American wine region, where most of the varieties derived from varieties brought after European colonization, is not exempt from this. This has allowed new wines to be provided with distinctive identities that are markedly different from the current homogeneous wine production. Moreover, varietal homogenization increases vineyard genetic vulnerability in relation to the emergence of grapevine diseases, to which the commonly cultivated varieties are not resistant. This review summarizes the oenological potential of minority or autochthonous grapevine varieties cultivated within the South American wine region, focusing on Argentina, Chile, and Bolivia. © 2019 Society of Chemical Industry

“…A high nitrogen fertilisation rate in the vineyard can result in lower accumulation of secondary metabolites, due to competition between the vegetative and reproductive tissues . In wines, urea foliar applications to Tempranillo grapevines resulted in a decrease in the content of higher alcohols, while improving the ethyl ester concentration . Moreover, low‐dose urea treatment increased the content of several volatile compounds, except C 6 compounds.…”

A review of the use of biostimulants in the vineyard for improved grape and wine quality: effects on prevention of grapevine diseases

et al. 2018

Foliar application of biostimulants (including resistance inducers or elicitors) in the vineyard has become an interesting strategy to prevent plant diseases and improve grape quality on the grapevine. This also represents a partial alternative to soil fertilisation, avoiding some of the negative effects to the environment from leaching of nutrients into the groundwater. The foliar applications that most promote the synthesis of secondary metabolites in grape berries are treatments with nitrogen, elicitors, other biostimulants, and waste from the agricultural industry. However, the impact of their use in the vineyard depends on a number of conditions, including mainly the type of compound, application rate, timing and number of applications, and cultivar. This review thus summarises the influence of biostimulants as foliar applications to grapevines on grape amino acids and their phenolic and volatile concentrations, to define the most important factors in their effectiveness. © 2018 Society of Chemical Industry.

Effect of foliar urea fertilisation on volatile compounds in Tempranillo wine

Abstract: It may be concluded that foliar urea fertilisation shows itself to be efficient in small doses as a complement to soil fertilisation to improve wine aroma.
