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.

‘Cabernet Sauvignon’ (Vitis vinifera L.) berry skin flavonol and anthocyanin composition is affected by trellis systems and applied water amounts

Trellis systems are selected in wine grape vineyards to mainly maximize vineyard yield and maintain berry quality. This study was conducted in 2020 and 2021 to evaluate six commonly utilized trellis systems including a vertical shoot positioning (VSP), two relaxed VSPs (VSP60 and VSP80), a single high wire (SH), a high quadrilateral (HQ), and a guyot (GY), combined with three levels of irrigation regimes based on different crop evapotranspiration (ETc) replacements, including a 25% ETc, 50% ETc, and 100% ETc. The results indicated SH yielded the most fruits and accumulated the most total soluble solids (TSS) at harvest in 2020, however, it showed the lowest TSS in the second season. In 2020, SH and HQ showed higher concentrations in most of the anthocyanin derivatives compared to the VSPs. Similar comparisons were noticed in 2021 as well. SH and HQ also accumulated more flavonols in both years compared to other trellis systems. Overall, this study provides information on the efficacy of trellis systems on grapevine yield and berry flavonoid accumulation in a currently warming climate.

The potential of multispectral/hyperspectral technologies for early detection of “flavescence dorée” in a Portuguese vineyard

“Flavescence dorée” (FD) is a grapevine quarantine disease associated with phytoplasmas and transmitted to healthy plants by insect vectors, mainly Scaphoideus titanus. Infected plants usually develop symptoms of stunted growth, unripe cane wood, leaf rolling, leaf yellowing or reddening, and shrivelled berries. Since plants can remain symptomless up to four years, they may act as reservoirs of FD contributing to the spread of the disease. So far, conventional management strategies rely mainly on the insecticide treatments, uprooting of infected plants and use of phytoplasma-free propagation material. However, these strategies are costly and could have undesirable environmental impacts. Thus, the development of sustainable and noninvasive approaches for early detection of FD and its management are of great importance to reduce disease spread and select the best cultural practices and treatments. The present study aimed to evaluate if multispectral/hyperspectral technologies can be used to detect FD before the appearance of the first symptoms and if infected grapevines display a spectral imaging fingerprint. To that end, physiological parameters (leaf area, chlorophyll content and photosynthetic rate) were collected in concomitance to the measurements of plant reflectance (using both a portable apparatus and a remote sensing drone). Measurements were performed in two leaves of 8 healthy and 8 FD-infected grapevines, at four timepoints: before the development of disease symptoms (21st June); and after symptoms appearance (ii) at veraison (2nd August); at post-veraison (11th September); and at harvest (25th September). At all timepoints, FD infected plants revealed a significant decrease in the studied physiological parameters, with a positive correlation with drone imaging data and portable apparatus analyses. Moreover, spectra of either drone imaging and portable apparatus showed clear differences between healthy and FD-infected grapevines, validating multispectral/ hyperspectral technology as a potential tool for the early detection of FD or other grapevine-associated diseases.

Terroir analysis and its complexity

Terroir is not only a geographical site, but it is a more complex concept able to express the “collective knowledge of the interactions” between the environment and the vines mediated through human action and “providing distinctive characteristics” to the final product (OIV 2010). It is often treated and accepted as a “black box”, in which the relationships between wine and its origin have not been clearly explained. Nevertheless, it is well known that terroir expression is strongly dependent on the physical environment, and in particular on the interaction between soil-plant and atmosphere system, which influences the grapevine responses, grapes composition and wine quality. The Terroir studying and mapping are based on viticultural zoning procedures, obtained with different levels of know-how, at different spatial and temporal scales, empiricism and complexity in the description of involved bio-physical processes, and integrating or not the multidisciplinary nature of the terroir. The scientific understanding of the mechanisms ruling both the vineyard variability and the quality of grapes is one of the most important scientific focuses of terroir research. In fact, this know-how is crucial for supporting the analysis of climate change impacts on terroir resilience, identifying new promised lands for viticulture, and driving vineyard management toward a target oenological goal. In this contribution, an overview of the last findings in terroir studies and approaches will be shown with special attention to the terroir resilience analysis to climate change, facing the use and abuse of terroir concept and new technology able to support it and identifying the terroir zones.
