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.

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.

Characterization of a Sémillon clonal population: exploring genetic diversity, metabolomic profiles, and phenotypic variations

Sémillon is a cultivated grape variety known for contributing to dry and sweet white wine production. However, only seven approved clones have been officially recognized in France[1]. In this study, we aimed to characterize the genetic diversity and metabolomic profiles of a Sémillon clonal population, shedding light on the potential variations within this important grape variety.

Drought responses of grapevine cultivars under different environments

Using grapevine genetic diversity is one of the strategies to adapt viticulture to climate change. In this sense, assessing the plasticity of cultivars in their responses to environmental conditions is essential. For this purpose, the drought tolerance of Grenache, Tempranillo and Semillon cultivars grafted onto SO4 was evaluated at two experimental vineyards, one located in Valencia (Spain) and the other in Bordeaux (France). This was done by assessing gas exchange parameters, water relations and leaf hydraulic traits at the end of the season.

Rootstock regulation of scion phenotypes: the relationship between rootstock parentage and petiole mineral concentration

Rootstocks not only provide tolerance to Phylloxera, but also ensure the supply of water and mineral nutrients to the whole plant. Rootstocks are an important way of adapting to environmental conditions while conserving the typical features of scion varieties. We can exploit the large diversity of rootstocks used worldwide to aid this adaptation. The aim of this study was to characterise rootstock regulation of scion mineral status and its relation with scion development.

Ultra-High Pressure Homogenization (UHPH): a technique that allows the reduction of SO2 in winemaking

Ultra-High Pressure Homogenization (UHPH) is an innovative, efficient and non-thermal technology that can be applied at different stages in winemaking in order to reduce or avoid the use of sulphites. During 2022 vintage, a batch of Xarel·lo must was processed by UHPH at 300 MPa with an inlet temperature (Ti) of 4 ºC. In order to verify the influence of the UHPH treatment in wine characteristics, alcoholic fermentations with this must (UHPH) were carried out and compared with a control batch (without SO2 addition (C)) and a sulphited batch, in which 60 mg/L of total SO2 (SO2) were added.
