Pinot noir: an endemic or a flexible variety?

Abstract

Pinot noir has its historical roots in Burgundy and is generally considered as an endemic vine variety which means that its adaptation is very specific to this environment and that its wines are the most expressive in the same particular situations. Now, Pinot noir has become an international variety because growers rely on its exceptional œnological potential and reputation to reproduce something excellent under their own conditions, and also because the general style of the wines is original and dominated by ‘finesse’ which is a new trend on the international wine market. In that context, it is interesting to evaluate the ability Pinot noir has to adapt, either as a vine variety interacting in a first time with the climate which is the entrance door to the terroir,, or as a wine in terms of ‘typicity’ and specific elements revealed by sensory analysis.

The method which is used is a survey of some sensory analysis of Pinot noir wines around the world done by the authors, which is based, first on the characterization of the degree of maturation on the main trend called ‘fruity unfolding’ (from non mature, to fresh, then mature, dried, jam or cooked fruit), second on the identification of some very specific elements such as general balance (acidity) or particular fruits (wild cherry) or elements of the ‘derived series’ (floral, spicy, mineral, balsamic, mushroom characters…).

The main analysis concerns the type of macro/meso-climate in relation to the wine ‘typicity’. The interest of the study is that wines are produced under a maximum range of situations. Some Burgundy terroirs under Semi-Continental climate being references and considered as able to produce some exceptional wines, the following climates are chosen: Continental (Cosne s/Loire, Alsace, Franconia, Valais), Continental Semi-Arid (Gansu), Cool – Mountain (Eastern Pyrénées – Hautes vallées), Cool (North Oregon, Australia – Victoria), Temperate – Cool (Loir et Cher, New Zealand – Malborough), Temperate (Friuli,), Mediterranean – Temperate (High Languedoc, Penedes, California – Monterey), Mediterranean – Mountain Kosovo), Mediterranean (Languedoc plain), Mediterranean – Semi-Arid (Mendoza-Tupungato), Subtropical (Carmelo – Uruguay), Subequatorial – High Altitude (Boyaca– Colombia).
The results show that:

Pinot noir can be cultivated and produce quality wines under many climates within the range of 1700-2300 °C; days of Huglin’s Heliothermal Index, which gives some security in front of the climate change.

The type of adaptation of Pinot noir depends on the elements of the wine ‘typicity’: it may be considered as ‘flexible’ because it reproduces very often on a wide range of climates the sensory characteristics of ‘fruity-cherry’ and ‘balance/elegance’; it may be considered as ‘endemic’ because it expresses a lot of specific sensory characters which depend on the ‘viticultural terroir’ (perception of acidity, wild cherry, artemisia, violet, mild spices, leather, truffle, chocolate, degree of excellence…).
That study needs to be deepened in the fields of micro-Climatology, .sensory analysis, grape berry Biochemistry.

Metabolomic study of mixed Saccharomyces cerevisiae yeast during fermentation

Alcoholic fermentation conducted by microorganism is a key step in the production of wine. In this process, interactions between different species of yeast are widely described but their mechanisms are still poorly understood. The interactions studied in wine are mainly between Saccharomyces and non-Saccharomyces species. Therefore, little is known about the mechanisms of interactions

Application of high-throughput sequencing tools for characterisation of microbial communities during alcoholic fermentation

Developments in high-throughput sequencing (HTS) technologies allow us to obtain large amounts of microbial information from wine and must samples. Thus approaches, that are aimed at characterising the microbial diversity during fermentation, can be enhanced, or possibly even replaced, with HTS-based metabarcoding. To reduce experimental biases and increase data reproducibility, we compared 3 DNA extraction methods by evaluating differences in the fungal diversity with Riesling alcoholic fermentation samples at four different vineyards. The fungal diversity profiling was done using the genetic markers ITS2 and D2 using metabarcoding. The extraction methods compared consisted of a commercial kit, a recently published protocol that includes a DNA enhancer, and a protocol based on a buffer containing common inhibitor removal reagents. All methods were able to distinguish vineyard effects on the fungal diversity, but the results differed quantitatively.

Oligosaccharides in red wines: could their structure and composition be influenced by the grape-growing

Oligosaccharides have only recently been characterized in wine, and the information on composition and content is still limited. In wine, these molecules are mainly natural byproducts of the degradation of grape berry cell wall polysaccharides. Wine oligosaccharides present several physicochemical properties, being one relevant factor linked to the astringency perception of wines (1,2). A terroir can be defined as a grouping of homogeneous environmental units based on the typicality of the products obtained. This notion is particularly associated with wine, being the climate and the soil two of the major elements of terroir concept.

Regulation of terpene production in methyl jasmonate treated cell-cultures

Terpenes are responsible for flavors and aromas of grapes, however, they also protect from radiation, participate in biotic stress and antioxidant mechanisms. The phytohormone methyl jasmonate (MeJA) mediates many of these stress responses and has been associated with increased terpene content in berries. Here, we generated transcriptomic data of Vitis vinifera cv. ‘Gamay’ cells treated with MeJA (100 μM) and cyclodextrins (50 μM) to understand these responses. Ontology analysis revealed that up-regulated genes (URGs) were enriched in jasmonic acid biosynthesis and signaling terms, as expected. Inspection of transcription factors (TFs) among URGs allowed us to study uncharacterized TFs.

Effect of alcoholic strength on the phenolic and furfural compounds of Brandy de Jerez aged in Sherry Casks®

Brandy is a spirit drink produced from wine spirit aged for at least six months in oak casks with a capacity of less than 1000 L and minimum alcohol by volume (ABV) of 36%. During the aging process, physicochemical and sensory changes take place. Manifested by colour, flavour or aroma variations that improve the quality of the initial distillate.
