Cultivation site effect on the quality of Moscato di Pantelleria

Abstract

In 1997 and 1999, sixteen cultivation sites of cv. Muscat of Alexandria different for pedological conditions, altitude and exposition were selected through all Pantelleria isle. In 1997 in each site, described and classified according to USDA Soil Taxonomy and FAO Soil Classification methods, grapes, collected at technological ripening, were microvinificated, following a standard procedure which allowed to obtain the naturally sweet wine DOC Moscato di Pantelleria. Wines, five months after vinification, were analysed by gaschromatography. Moreover they were described by sensorial analysis using a non structured parametric card. In 1999, grape maturation trend was observed in the same cultivation sites, At harvest time, productive parameters were collected for the vines of each site; furthermore grapes of each site were collected and microvinificated and the main juoce parameters were determinated.
The different pedological substrates, but above all, the expositions, summarised in some landscape units, determined important differences in the accumulation process which delayed up to 40-50 days the ripening among the early and late sites. Wines produces in the early sites presented a particular sensorial profile either in quantity and in quality, with sensorial descriptors linked to citrus, white flowers and green legumes, while in wines produces with grapes of late sites, sensorial descriptors were linked to fruit jam and stone fruits. Different mixture of wines coming from the two different origins resulted in complex and elegant wines.

Effects of heat and water stress on grapevine health: primary and secondary metabolism

Grapevine resilience to climate change has become one of the most pressing topics in the Viticulture & Enology field. Vineyard health demands understanding the mechanisms that explain the direct and indirect interactions between environmental stressors. The current climate change scenario, where drought and heat-wave are more frequent and intense, strongly demands improving our knowledge of environmental stresses. During a heatwave, the ambient temperature rises above the plant’s average tolerance threshold and, generally, above 35 oC plant’s adaptation to heat stress is activated.

Evaluation of aroma characteristics in Vitis amurensis grapes across different regions by using HS-SPME-GC/MS

Background: Aroma compounds are important secondary metabolite in grapes and play important roles in the flavor and quality of grape berries and their wines. Vitis amurensis grape belongs to the East Asian Vitis spp., with excellent cold and disease resistance, and exhibits strong brewing potential. However, it has not been effectively utilized and there is no systematic research on the aroma compounds of V. amurensis grapes.
Methods: To provide sufficient experimental evidence for the characteristic aroma of V. amurensis grape, HS-SPME-GC/MS was used to identify the aroma compounds of five V. amurensis (‘Beiguohong’, ‘Beiguolan’, ‘Shuangfeng’, ‘Shuanghong’, ‘Shuangyou’) and three interspecific hybrids (‘Beibinghong’, ‘Xuelanhong’, ‘Zuoyouhong’) grapes in Zuojia and Ji’an. The grape berries were collected at harvest in 2020, 2021 and 2022.

Image based vineyard yield prediction using empirical models to estimate bunch occlusion by leaves

Vineyard yield estimation brings several advantages to the entire wine industry. It can provide useful information to support decision making regarding bunch thinning practices, harvest logistics and marketing strategies, as well as to manage stored wine and cellar tanks allocation. Today, this estimation is performed mainly using manual methods based on destructive bunch sampling.
