Influence of the agronomic management on the aroma of Riesling wines

Nitrogen fertilisation of grapevines is known to influence not only plant development and production yield, but also yeast assimilable nitrogen (YAN). This parameter is related to the growth of yeast during fermentation and the quality of wines, since nitrogen is involved in the biochemical production of the fermentation aroma. The work compared three agronomic managements […]

Effect of early defoliation on volatile composition and sensory properties of aglianico red wines

AIM: The aim of this work was to study the influence of early defoliation in the vineyard on Aglianico wines quality from Apulia region (Italy). Early defoliation was conducted in commercial Aglianico (Vitis vinifera L.) vineyards situated in Apulia region in Italy during the 2018 season. METHODS: Three defoliation treatments were carried out in the […]

Targeted UHPLC-QqQ-MS/MS metabolomics for phenol identification in grapevine and wine: study of a Tempranillo clone with a dark-blue berry colour

Grapevine vegetative multiplication allows the accumulation of spontaneous mutations and increase intra-cultivar genetic diversity that can be exploited to maintain grape wine quality, tipicity and adaptation to different climate conditions. Non-volatile phenolic compounds are intrinsic components of grape fruits and derived products, particularly wine. They constitute a heterogeneous family of compounds and play an important […]

Sensory and chemical phenotyping of wines from a F1 grapevine population

The European Green Deal, a concept of the European Commission, aims at the reduction of pesticides in EU agriculture for 2030 by 50%. Viticulture uses the largest amounts of fungicides in the EU, compared to other crops such as grains. In order to achieve the ambitious target of 50% pesticide reduction in viticulture, the increased […]

Smartphone application use as a tool for water supply management

Uruguay had an average annual rainfall of 1200 mm characterized by a high monthly variability, which generates periods of water deficit and excess. The rational water management, in the moments of deficit becomes more and more necessary in a viticulture that for this region is not used to irrigation. Therefore, permanent and real-time monitoring of […]

Effect of late pruning on yield and wine composition in monastrell wines

Global warming is shifting vine phenology, resulting in a decoupling of phenolic and technological berry ripening. This is altering the balance of fruit traits, which is key relevance to winegrowers, particularly in arid and semi-arid areas. Our aim was to test late pruning as an useful tool to delay grape ripening and to assess the […]

Methyljasmonate versus nanomethyljasmonate: effect on monastrell nitrogen composition

AIM: The aim of this work was to evaluate the effect of preharvest application in Monastrell berries using two different types of applications: conventional treatments (methyl jasmonate) and nanocompounds (nanomethyl jasmonate) on Monastrell nitrogen composition in grapes and wines. METHODS: The treatments was applied during two vintages (2019 and 2019) in a plot located in […]

Methyl jasmonate versus nano methyl jasmonate: effects on anthocyanins mature evolution in monastrell grapes

AIM: The climate change is afecting particulary to the South of Spain, with high temperatures. It is important to develop new strategies in order to mantain the quality of wines. One of this strategies is the use of elicitors which increase the defense in plants and also increase the content of secondary metabolites, such as […]

Impact of electrolyzed water applied as an alternative treatment in vineyard on grape and wine quality

The main issues in viticulture are to highly decrease the use of phytochemicals. Electrolyzed water (EW) is one of the possible alternative when illness pressure is not too high. The objective of that work was to characterize the impacts on grape and wine quality when using EW compared to those obtained from organic and conventional […]

Application to grapevine leaves of different doses of urea at two phenology stage: effect on the aromatic composition of red wine

AIM: This research aimed to study the effect and efficiency of foliar application of urea on the aromatic composition of red wines elaborated from Tempranillo grapes. METHODS: This study was carried out in 2018 and 2019. The plot was located in the North of Spain. The grapes were Vitis vinifera L. Tempranillo and grafted on […]
