Physicochemical behaviour of wine spirit and wine distillate aged in Sherry Casks® and Brandy casks

Abstract

Brandy is a spirit drink made from “wine spirit” (<86% Alcohol by Volume – ABV; high levels of congeners and they are mainly less volatile than ethanol), it may be blended with a “wine distillate” (<94.8%ABV; low levels of congeners and these are mainly more volatile than ethanol), as long as that distillate does not exceed a maximum of 50% of the alcoholic content of the finished product[1]. Brandy must be aged for at least 6 months in oak casks with <1000L of capacity. During ageing, changes occur in colour, flavour, and aroma that improve the quality of the original distillate. These changes are influenced by factors such as the ageing process itself, cask characteristics (botanical origin, volume, toasting degree, previous usage), and pre-treatments like the sherry wine-seasoning process (Sherry Cask®)[2]. In this work, the physicochemical behaviours of wine spirits and wine distillates aged in Sherry Casks® and Brandy casks have been compared.

Methods: “Wine spirit” obtained at 77%ABV and “wine distillate” at 94.6%ABV were diluted with demineralized water to 68%ABV for ageing in American oak casks, medium toast, 500L of capacity and seasoned by 18%ABV Oloroso Sherry wine for 3 years (Sherry Cask®) and “Brandy casks” were only used for ageing brandy for 3 years. It was carried out in duplicate, following a static ageing for 2 years. Oenological parameters, chromatic characteristics, and total polyphenol index (TPI) were carried out according to OIV methodology. Volatile substances were determined by GC-FID.

Results: A substantial difference was observed between the distillates aged in Sherry Cask® and Brandy cask in the parameters influenced by ageing. Aged in Sherry Cask® showed greater increase in TPI and colour. These 2 types of distillates, despite their different initial characteristics, and therefore, their levels of volatile substances, show a similar evolution in the trends of these compounds.

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].

Dynamics of Saccharomyces cerevisiae population in spontaneous fermentations from Granxa D’Outeiro terroir (DOP Ribeiro, NW Spain)

Granxa D’Outeiro is a recovered ancient vineyard located in the heart of DOP Ribeiro, where traditional white grapevine varieties are growing under sustainable management. Spontaneous fermentations using grape must from Treixadura, Albariño, Lado, Godello, and Loureira varieties were carried out at experimental winery of Evega. Yeasts were isolated from must and at different stages of fermentation. Those colonies belonging to Saccharomyces cerevisiae were characterized at strain level by mDNA-RFLPs.

Oenococcus oeni clonal diversity in the carbonic maceration winemaking

This essay was aimed to describe the clonal diversity of Oenococcus oeni in the malolactic fermentation of the carbonic maceration (CM) winemaking. The free and the pressed liquids from CM were sampled and compared to the wine from a standard winemaking with previous destemming and crushing (DC) of grapes [1]. O. oeni strain typification was performed by PFGE as González-Arenzana et al. described (2014) [2]. Results showed that 13 genotypes, referred as to letters, were distinguished from the 49 isolated strains, meaning the genotype “a” the 27%, the “b” the 14%, the “c” the 12%, the “d and e” the 10 % each other, and the remaining ones less than the 8% each one.

Phenolic composition of Cabernet Sauvignon wines from Argentina, Portugal and Spain

Grape and wine phenolic compounds have been shown to be highly related to both wine quality (color, flavor, and taste) and health-promoting properties (antioxidant and cardioprotective, among others). The aim of this work was to evaluate and compare the phenolic contents of Cabernet Sauvignon wines from different geographical areas and climatic conditions, namely from Argentina, Portugal and Spain vintage 2022. In addition, the phenolic profiles of the Portuguese wines from three vintages (2020, 2021, 2022) was compared.

Characterization of spoilage yeasts from Malbec grapes from San Rafael wine region (Argentina)

The yeast ecosystem in grape musts is quite broad and depends on the region and the health of the grapes. Within this, there are yeasts that can generate fermentative deviations and/or cause defects in the wine. It is very important to address this issue because there are significant economic losses in the wine industry when the fermentation process and/or the organoleptic characteristics of the wine are negatively affected, even more today since climate change has a marked effect on the composition of this ecosystem. The aim of this work is to characterize the behavior regarding detrimental oenological features of potential spoilage yeasts isolated from viticultural environments.
