Oxidability of wines made from Spanish minority grape varieties


The phenolic profile of a wine plays an essential role in its oxidative capacity and in both white and red wines it defines its shelf life[1]. The study of minority varieties to produce wines with peculiar characteristics necessarily includes the phenolic and oxidative characterization of the wines produced. This paper presents the study of wines made from 24 minority and majority white and red grape varieties, focusing on phenolic characteristics (total phenols, slightly polymerized phenols, highly polymerized phenols, anthocyanins…), color, as well as parameters related to the oxidability of the wines and their capacity to consume oxygen [2]. The white wines studied were made with the following varieties: Albarín, Albillo, Doña Blanca, Godello, Legiruela, Malvasía, Puesta en Cruz, Rufete Blanco, Sauvignon Blanc, Verdejo and Viognier and the red wines with Bruñal, Cabernet Sauvignon, Cenicienta, Estaladiña, Juan García, Mandón, Mencía, Merenzao, Merlot, Negro Saurí, Prieto Picudo, Tempranillo, Tinta de Toro. The preliminary results obtained are very interesting and indicate that regardless of the winery, the wines of each variety have their own characteristics, showing a lower capacity to consume oxygen in white wines made with Puesta en Cruz, Rufete Blanco, Viognier or Albillo, which is reflected in their lower browning compared to wines made with Albarín, Verdejo or Sauvignon Blanc, which have a higher browning rate. In the case of red wines, those made with Mandón, Cenicienta or Juan García show a greater capacity to consume oxygen than those made with Negro Saurí, Merenzao or Estaladiña.

Impact of climate on berry weight dynamics of a wide range of Vitis vinifera cultivars 

In order to study the impact of climate change on Bordeaux grape varieties and to assess the behavior of candidate grape varieties potentially better adapted to the new climatic conditions, an experimental vineyard composed of 52 grape varieties was planted in 2009 at the INRAE Bordeaux Aquitaine center[1]. Among the many parameters studied since 2012, berry weight for each variety was measured weekly from mid-veraison to maturity, with four independent replicates. The kinetics obtained allowed to study berry growth, a key parameter in grape composition and yield.

Sparkling wines and atypical aging: investigating the risk of refermentation

Sparkling wine (SW) production entails a two-steps process where grape must undergoes a primary fermentation to produce a base wine (BW) which is then refermented to become a SW. This process allows for the development of a new physicochemical profile characterized by the presence of foam and a different organoleptic profile.

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].

Comparison of ancestral and traditional methods in the elaboration of sparkling wines; preliminary results

Top quality sparkling wines (SW) are mostly produced using the traditional method that implies a second fermentation into the bottle[1]. That is the case of sparkling wines of reputed AOC such as Champagne, Cava or Franciacorta. However, it seems that the first SW was elaborated using the ancestral method in which only one fermentation takes place[2]. That is the case of the classical SW from the AOC Blanquette de Limoux[3]. In both cases, SW age in the bottle during some time in contact with lees favoring yeast’s autolysis[4]. There is a lot of information about traditional method but only few exists about ancestral method. The aim of this work was to compare SW made by the ancestral method with SW made by the traditional method.

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.
