The potential of some native varieties of Argentina for the production of sparkling wines. Effect of lees contact time 

Abstract

Grapevine varieties from South-America, commonly known as criollas, originated because of the natural crossbreeding of grapevine varieties brought by the Spaniards. The objective of this work was to evaluate the potential of some varieties to produce sparkling wines considering the effect of lees contact time. The following varieties were used: Moscatel Rosado, Criolla Chica, Pedro Gimenez, Blanca Oval, Canelón, and the European variety Chardonnay (control), planted in the ampelographic collection of EEA Mendoza INTA (Argentina). Pilot-scale vinifications were carried out to obtain the base wines, in 20 L glass containers. The second fermentation was performed through the traditional method. A completely randomized design was applied in triplicate. The treatments were: T1, 135 days of lees contact (LC); T2, 180 days LC; T3, 270 days LC; and T4, 360 days LC. General chemical analyses were carried out according to OIV methods, proteins and polysaccharides characterization by HRSEC-RID, and sensory analyses using the flash profile technique. The base wines had the following analytical parameters: total acidity 7.0 ± 0.5 g/L; pH 3.20 ± 0.15; alcohol 12.0 ± 0.2 % v/v, and volatile acidity 0.35 ± 0.15 g/L. At the sensory level, in the Moscatel Rosado wines, floral and fruity notes were prominent in T1 and T2, decreasing towards T3 and T4. For the Pedro Giménez and Blanca Oval varieties, fruit descriptors predominated in T1 and T2, which then decreased significantly over time (T3 and T4). Criolla Chica and Canelón were characterized by attributes of nuts and toasted bread, especially with longer lees contact time. In general, all varieties showed good balance in the mouth, but Chardonnay stood apart from the rest, with descriptors such as yeast, mouthfeel, and higher color intensity. These results revealed the technological potential of autochthonous genetic material to diversify the production of sparkling wines, providing regional identity.

Application of UV-B radiation in pre- and postharvest as an innovative and sustainable cultural practice to improve grape phenolic composition

Ultraviolet radiation (UVR) is a minor part of the solar spectrum, but it represents an important ecological factor that influences many biological processes related to plant growth and development. In recent years, the application of UVR in agriculture and food production is emerging as a clean and environmentally friendly technology.
In grapevine, many studies have been conducted on the effects of ambient levels of UVR, but there are few considering the effects of UV-B application on grape phenolic composition under commercial growing or postharvest conditions.

Under-vine management effects on grapevine vegetative growth, gas exchange and rhizosphere microbial diversity

The use of cover crops under the vines might be an alternative to the use of herbicides or tillage, improving grapevine quality and soil characteristics. The aim of this research was to study the implications of different management strategies of the soil under the vines (herbicide, cultivation or cover crops) on grapevine growth, water and nutritional status, gas exchange parameters and belowground microbial communities.
The experimental design consisted in 4 treatments applied on 35L-potted Tempranillo vegetative grapevines with 10 replicates each grown in an open-top greenhouse in 2022 and 2023. Treatments included two cover crop species (Trifolium fragiferum and Bromus repens), herbicide (glyphosate al 36%) and an untreated control.

First results on the chemical composition of red wines from the pressing of marc

In the Bordeaux vineyards, press wine represents approximately 15% of the total volume of wine produced[1]. Valuing this large volume of wine is necessary from an economic point of view, but also because of their organoleptic contribution to the blend, and their contribution to the construction of wines for laying down. Therefore, this study was developed considering the lack of recent scientific knowledge on the composition of red press wines. The aim of this study is to establish an initial assessment of their chemical composition including aromatic compounds and a phenolic part.

Role of anthocyanins and copigmentation in flavonol solubility in red wines 

Over the last years, due to climate change, several red wines, such as the Sangiovese wines, have been often subjected to loss of clarity due to the formation of deposits of fine needle-shaped crystals. This phenomenon turned out to be due to an excess of quercetin (Q) and its glycosides (Q-Gs) in wines. These compounds are synthesized to a large extent when grapes are excessively exposed to UVB radiations in vineyards[1]. Unfortunately, it is not easy to predict the degree of Q precipitation because its solubility strongly depends on the wine and matrix composition[2].

Mapping grapevine metabolites in response to pathogen challenge: a Mass Spectrometry Imaging approach

Every year, viticulture is facing several outbreaks caused by established diseases, such as downy mildew and grey mould, which possess different life cycles and modes of infection. To cope with these different aggressors, grapevine must recognize them and arm itself with an arsenal of defense strategies.
The regulation of secondary metabolites is one of the first reactions of plants upon pathogen challenge. Their rapid biosynthesis can highly contribute to strengthen the defense mechanisms allowing the plant to adapt, defend and survive.
