Leaf elemental composition in a replicated hybrid grape progeny grown in distinct climates

Aim‐ Rootstocks provide protection against soil borne pests and are a powerful tool to manipulate growth, fruit composition and wine quality attributes

Tannins are chemically diverse polyphenols contributing to important sensory attributes of food and beverages. In wine, their structure and quantity depend on several factors, such as the grape variety, climate, soil, viticultural and enological practices and the wine-aging process.

Global warming is representing a major challenge for Mediterranean agriculture. Improving irrigation and identifying or obtaining varieties tolerant to water scarcity are being constantly pursued. In this research we contrasted 5 varieties commonly cultivated in many wine-growing areas (Merlot, Garnacha, Shyraz, Malvasia and Muscat of Alexandria) with other five varieties mainly cultivated in Andalusia, Spain (Palomino fino, Rome, Doradilla, Tinto Velasco and Pedro Ximénez).

Clay-based ceramic vessels (jars, pyhtoi, etc.) for wine fermentation and aging processes have been used in several cultures for millennia. This know-how still in practice in several countries of the Armenian highland is gaining worldwide in curiosity, popularity, and interest. Ceramic pots are famous among traditional winemakers for their benefits such as temperature regulation, natural cooling system, favorable oxygen exchange, and impact on pH, which are different from those of stainless steel, wood barrels, or concrete.

Terroir studies are common nowadays but few have used precise pedoclimatic measures in order to evaluate the precocity potential. The objectives of this work were (i) to assess the effect of main terroir parameters (soil, climate and topography) influencing the phenological development of the vine, and (ii) to evaluate a geostatistic approach by using a high number of already existing plots (higher variability) to analyze the terroir parameters’ impact.
