AGEING REVEALS THE TERROIR OF AGED RED BORDEAUX WINES REGARDLESS OF THE VINTAGES! TARGETED APPROACH USING ODOROUS COMPOUNDS LEVELS INCLUDING TERPENES AND C13 NORISOPRENOIDS

Abstract

The chemistry of wine is notably complex and is modified by ageing of the bottles. The composition of wines is the result of vine production (under the influence of vintage, climate and soils); yeast production (under the influence of juice composition and fermentation management); lactic bacteria production (under the influence of young wine composition and malolactic fermentation management); and of the ageing process either in vats, barrels or bottles or both. The composition is linked to the quality perceived by consumers but also to their origin, sometimes associated to the “terroir” concept.

Even if the chemical identity of a wine is shaped by a large variety of factors (soil, climate, varieties, microbiology, ageing process), we know now that the terroir and the maturation plays a key role in the sensorial and chemical identity of wines even after ageing (1–4). The aims of that study was to explore the links between terroir, ageing or vintages and the chemical composition. A targeted approach have been tested. It involves the quantification of molecular markers such as esters, terpenes, norisoprenoids or sulphur compounds. It have been applied to a large set of wines composed by 80 samples produced by 7 wineries during a selection of vintages between 1990 to 2007. The statistical analysis of the results permits to highlight similar compositions between wines produced in the same winery despite the variation of berry composition due to the vintage, the variations dues to technical choices and to ageing time. In the current study, the whole volatile composition is essential to the uniqueness of the wines because there are no compounds that are exclusively involved in discrimination of estate. This shows the complex effect of the grape and wine matrix on achieving a typical product. Overall, in the aromatic matrix, there is an existence of a hierarchy in the importance of compounds that permits the unicity of Bordeaux estate. Hence, three families of compounds (terpenes, norisoprenoids and esters) which made it possible to discriminate between the seven Bordeaux estates studied and are therefore influenced by the composition of the grapes. These include TDN, vitispirane, β-damascenone, terpinen-1-ol, α-terpinene, methyl salicylate, cis-linalooxide, ethyl esters of fatty acids (C₄C₂, C₆C₂, C₈C₂) and many others. It’s interesting to note that even after years of bottle ageing, the imprint of the grape is still visible. The personality of each estate through its specific terroir is therefore an indispensable element for the aromatic singularity of each great wine.

Influence of agrophotovoltaic on vine and must in a cool climate

The current energy crisis means that interest in agrophotovoltaics has increased significantly. The reason behind this is that the system aims to combine agricultural production with energy production. During the three-year period from 2020 to 2022, the effects of photovoltaic panels on the vine, the yield and the quality of the must were studied in Walenstadt in northern Switzerland, an area with a cool, humid climate. 65 Pinot noir vines were planted in the 160m2 study area. Because of the large edge effects, only 3 repetitions with 4 vines each could be created. A significantly lower leaf infestation by Plasmopara viticola was observed among the panels in each of the three years.

INOCULATION OF THE SELECTED METSCHNIKOWIA PULCHERRIMA MP1 AS A BIOPROTECTIVE ALTERNATIVE TO SULFITES TO PREVENT BROWNING OF WHITE GRAPE MUST

Enzymatic browning (BE) of must is caused by polyphenol oxidases (PPOs), tyrosinase and laccase. Both PPOs can oxidize diphenols such as hydroxycinnamic acids (HA) to quinones, which can later polymerize to form melanins [1], which are responsible of BE in white wines and of oxidasic haze in red wines. SO₂ is the main tool used to protect must from BE thanks to its capacity to inhibit PPOs [2]. However, the current trend in winemaking is to reduce and even eliminate this unfriendly additive. Among the different possible alternatives for protecting must against BE, the inoculation with a selected Metschnikowia pulcherrima MP1 is without any doubt one of the most promising ones.

CHEMICAL DRIVERS OF POSITIVE REDUCTION IN NEW ZEALAND CHARDONNAY WINES

According to winemakers, wine experts and sommeliers, aromas of wet stone, mineral, struck match and flint in white wines styles, such as those produced from Vitis vinifera L. cv. Chardonnay, are considered to be hallmarks of positive reduction.1,2 In recent years, the production of Chardonnay styles defined by aroma characteristics related to positive reduction has become more desirable among wine experts and consumers. The chemical basis of positive reduction is thought to originate from the concentration of specific volatile sulfur compounds (VSCs), including methanethiol (MeSH) imparting mineral and chalk notes,3 and benzenemethanethiol (BMT) responsible for struck match and flint.1,4

IMPACT OF ABIOTIC AND BIOTIC FACTORS ON BIOADHESION PROPERTIES OF BRETTANOMYCES BRUXELLENSIS

Brettanomyces bruxellensis is an ubiquitous yeast associated with different fermentation media such as beer and kombucha, where its presence is beneficial to bring an aromatic typicity. However, it is a main spoilage yeast in wines, in which it produces volatile phenols responsible for organoleptic deviations causing significant economic losses (Chatonnet et al., 1992). Cellar and winery equipment’s are considered as the first source of contamination, during fermentation and wine ageing process (Connel et al., 2002). Indeed, it is possible to find B. bruxellensis in the air, on walls and floors of the cellars, on small materials, vats and barrels.

WHICH TERROIR-RELATED FACTORS INFLUENCE THE MOST VOLATILE COMPOUND PRODUCTION IN COGNAC BASE WINE?

Cognac is a famous spirit produced in southwest France in the region of the eponymous town from wines mainly from Vitis vinifera cv. Ugni blanc. This variety gives very acidic and poorly aromatic base wines for distillation which are produced according to a very specific procedure. Grapes are picked at low sugar concentrations ranging 13-21 °Brix and musts with high turbidity (>500 NTU) are fermented without sulphite addition [1]. Fermentative aromas, as esters and higher alcohols, are currently the main quality markers considered in Cognac spirits.
