Greek and Cypriot grape varieties as a sustainable solution to mitigate climate change

Abstract

Aim: The aim of this report is to present evidence on the potential of Greek and Cypriot grape varieties to serve as a sustainable solution to mitigate climate change.

Methods and Results: The work provides a review of recent works involving Greek and Cypriot varieties’ performance under high temperatures and increased dryness.

Conclusions: 

Climate change could threaten the existing balance between local environmental conditions and vitivinicultural production systems over the majority of wine producing areas. The subsequent decrease in the suitability of the current winemaking regions will require, apart from short-term adjustments in vineyard management, the adaptation of plant material by the use of late-ripening and drought resistant varieties and clones. Greek and Cypriot grape cultivars appear to grow well under dryland conditions, and additionally they mature their crop later than most of the well-established international varieties. However limited evidence exists regarding the direct effects of high daytime temperatures and drought especially on the quality of their grapes. This information would greatly assist grape growers in improving cultivar selection and adjusting management decisions.

Significance and Impact of the Study: Indigenous grapevine varieties of the semiarid viticultural regions of Greece and Cyprus have received much less attention compared to other grapes native to Mediterranean areas and therefore deserve to be better studied as a sustainable solution in the context of climate change. However, substituting existing varieties will change the “identity” of (mainly) European wine appellations, therefore the effectiveness of any strategy depends on both the willingness of grape growers and consumers to accept new varieties and also on the flexibility of current legislation.

Varietal differences between Shiraz and Cabernet sauvignon wines revealed by yeast metabolism

This study investigated if compositional differences between Shiraz and Cabernet Sauvignon grape varieties could influence the production of yeast-derived compounds. This work was based on the analysis of 40 experimental red wines made in triplicate fermentations from grapes harvested from two consecutive vintages in New South Wales (Australia). Grapes were picked at three maturity stages using berry sugar accumulation as physiological indicator, from nine commercial vineyards located in three different climatic regions (temperate, temperate-warm and warm-hot). A range of 30 yeast-derived wine volatiles including esters and alcohols were quantified by HS/SPME-GC/MS. Ammonia, amino-acids and lipids were analysed in the corresponding grapes. The juice total soluble solids (°Brix) in addition to the wine alcohol and residual sugar levels were also measured. The influence of grape maturity on wine ester composition was also variety dependent, particularly for higher alcohol acetate and ethyl ester of branched acids. This study highlights that varietal differences observed in Shiraz and Cabernet Sauvignon wines involve fermentation-derived compounds irrespective of the site (soil, climate, viticultural practices).

The legal concept of “cultural heritage” to refurbish the wine sector’s priorities

Following the latest oiv global report (april 26, 2024), the prevailing perception of wine consumption finds itself undergoing one of its most challenging adjustments. It’s plausible to anticipate a shift in the scope of pdo wines towards more human-centered products (wells and stiefel, 2019), necessitating the entire sector to adapt strategies to public interest patterns (touzeau, 2010: 17-31). Previously, a dominant notion of cultural property underscored the value of wine regions; the primary interest revolved around estate owners and retailers, along with vigneron tales.

Metabolomics for grape and wine research: exploring the contributions of amino acids to wine flavour

A critical aspect of wine quality is the overall expression of wine flavour, which is formed by the interplay of volatile aroma compounds, their precursors, and taste and matrix components.
Grapes directly contribute to wine only a small number of potent aroma compounds, and the unique
sensory attributes and perceived quality of a wine result from combining 100s of metabolites of grapes, yeast and bacteria, and oak wood.

Application to grapevine leaves of different doses of urea at two phenology stage: effect on the aromatic composition of red wine

This research aimed to study the effect and efficiency of foliar application of urea on the aromatic composition of red wines elaborated from Tempranillo grapes.

Development, validation and application of a fast UHPLC-HRMS method for the analysis of amino acids and biogenic amines in wines and musts.

The amino acids in grape juice are an important nitrogen source for yeast during alcoholic fermentation. Additionally, certain AAs are precursors to some of the volatile compounds found in wine and overall
