Agronomic and oenological behavior of the minority Mandón variety on two rootstocks in the D.O. Arribes

Abstract

A large population of vines of the Mandón minority red variety (synonymous with Garró) has been located in old vineyards of the D.O. Arribes (Zamora and Salamanca) to conserve and recover this minority variety. The wines made with this variety are characterized by their good structure and color, interesting harmony, an excellently low pH, with high acidity, as well as complex aromas of blue fruits and a marked and expressive minerality.

 

The objective of this work is to know the agronomic and oenological suitability of the minority variety Mandón (Garró) on two rootstocks, 110-R and 3309-C in the DO Arribes. The study was carried out in the 2014-2019 period in a trial located in the town of Villarino de los Aires (Sa). The vines have been trained on a trellis, NNE-SSO orientation and bilateral Royat cordon formation. The plot soil, characteristic of the D.O. Arribes is slightly acidic, shallow, with a loamy-sandy texture and low in organic matter.

 

The results show that the vegetative development of Mandón on 110-R indicates that it is more vigorous than 3309-C, with a higher weight of pruning wood and vine shoots. In the trend of this vigor, the 110-R rootstock is slightly more productive than the 3309-C, showing a greater number of clusters per vine and higher yield, although with somewhat smaller berries. The berry quality parameters indicated that the 3309-C rootstock reaches a probable alcoholic degree and a total acidity higher than 110-R. The results reveal that the Mandón variety obtains a better adaptation and conjunction with the 110-R rootstock than with 3309-C, with a better behavior in slightly acid soil, showing overall better vegetative and productive balance with a berry good quality.

Influence of different Lachancea thermotolerans strains in wine acidity

Wine acidity is a parameter of great importance that influences different quality factors of the product such as biological stability or organoleptic characteristics. In the current context of climate change, which gives rise to wines with higher levels of ethanol and lower acidity, the biological acidification with yeast species such as Lachancea thermotolerans could be a solution.
In this work, the effect of the inoculation of different L. thermotolerans on the acidity of wine was studied.

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.

Grapevine adaptation to drought and resistance to Neofusicoccum parvum, causal agent of Botryosphaeria dieback

The sustainability of viticulture in response to climate change has been addressed mainly considering agronomic impacts, such as water management and diseases, either separately or together.
In grapevines, there is strong evidence that different genotypes respond differently to biotic and abiotic stresses. A screening was conducted on various local cultivars in response to drought and Neofusicoum parvum infection aiming to evaluate their susceptibility to abiotic stress and resistance to fungal diseases.

The generation of suspended cell wall material may limit the effect of ultrasound in some varieties

The disruptive effect exerted by high-power ultrasound (US) on plant cell walls, natural barriers to the diffusion of compounds of interest during the maceration of red wines, is established as the reason behind the chromatic improvement that its treatment causes. However, sometimes this improvement is not observed, especially with short maceration times. The presence of a high quantity of suspended cell wall material, which formation is favored by the sonication, could be the cause of this lack of positive results since this cell wall material has a high affinity for phenolic compounds.

Effect of foliar application of urea and nano-urea on the cell wall of Monastrell grape skins

The foliar application of urea has been shown to be able to satisfy the specific nutritional needs of the vine as well as to increase the nitrogen composition of the must. On the other hand, the use of nanotechnology could be of great interest in viticulture as it would help to slow down the release of urea and protect it against possible degradation. Several studies indicate that cell wall synthesis and remodeling are affected by nitrogen availability.
