Similarities among wine aromas and landscape scents around the vineyard in five Mediterranean sites

Abstract

We compared 68 aroma compounds in wines from 5 vineyards in order to see similarities among the wine aroma and the scent of some of the main native plants from the respective vineyards. The work started with characterising the plant vegetation and the main plants and herbs in the boundaries and field growing in each 5 selected vineyards in Catalonia, Spain. Then 3 wines from each vineyard were analysed for aroma compounds and sensory description. In spring-early summer of 2021, 168 plants were recognised in the prospected sites. We found differences in the plant species diversity that characterised each vineyard landscape. Each vineyard had a particular set of plant species with a unique mix of aroma compounds. We compared the aromas of the wines and the aromas of the plants and found several matches among them. Further studies may offer a better understanding but it seems to be a connection or similarity among the landscape’s aroma and the wines obtained in proximity. Among the compounds with the highest odorant value found are the nosioprenoids ionone and damascenone and terpenes with floral and fruity aromas. This research allows a better understanding of the landscape and wines and to visualize the importance of preserving biodiversity as a management criteria and highlight its value in the vineyards. It can also be a tool for communication between the winemaker and the consumer.

Rootstock impact on foliar symptom expression of esca on Vitis vinifera cv. Cabernet-Sauvignon

Trunk diseases and esca in particular, represent a major threat to the sustainability of the vineyards. The percentages of unproductive vines in a plot could vary from 4% to over 20 % depending on local conditions and vintages.

Bioprotective non-Saccharomyces yeast as an alternative to sulfites for the winemaking process

Sulfur dioxide (SO2) is used in winemaking due of its antioxidant, antioxydasic and antiseptic properties. Excessive amount of SO2 can negatively impact wine sensory perception and be detrimental for health. Agri-food industries are more transparent towards consumers concerning addition of sulfites, and oenology is no exception in this clairvoyance. As a consequence, the increase of consumers preference for wine with low or absent of sulfites addition is notorious. In this context, the impact of low/zero sulfites winemaking process on the microbial community should be evaluated. Moreover, microbial agents corresponding to bioprotective cultures represent a growing interest as an alternative to sulfites preservation in the early stages of vinification. However, scientific studies conducted to demonstrate their real effect are almost rare.

Intra-block variations of vine water status in time and space

Vine water status was measured on 96 plots of three vines inside a vineyard block of 0.28 ha during three years: 2003, 2004 and 2005. Three physiological indicators were implemented: stem water potential, carbon isotope discrimination measured on grape sugars at ripeness (δ13C) and canopy temperature measured by high resolution remote sensing. For stem water potential, measurements were taken on every single vine of each plot.

INFLUENCE OF THE THICKNESS OF OAK ALTERNATIVES ON THE COMPOSITION AND QUALITY OF RED WINES

Aging red wines in oak barrels is an expensive and laborious process that can only be applied to wines with a certain added value. For this reason, the use of oak alternatives coupled with micro-oxygenation has progressively increased over recent years, because it can reproduce the processes taking place in the barrels more economically and quickly [1]. Several studies have explored how oak alternatives [2-5] can contribute to wine composition and quality but little is known about the influence of their thickness.
