Future scenarios for viticultural climatic zoning in Europe

Abstract

Climate is one of the main conditioning factors of winemaking. In this context, bioclimatic indices are a useful zoning tool, allowing the description of the suitability of a particular region for wine production. In this study, we compute climatic indices for Europe, characterize regions with different viticultural aptitude, and assess possible variations in these regions under a future climate conditions using a state-of-the-art regional climate model. The indices are calculated from climatic variables (mostly daily temperatures and precipitation) obtained from the regional climate model COSMO-CLM for recent and future climate conditions. Maps of theses indices for recent decades (1961-2000) and for the XXI century (following the SRES A1B scenario) are considered to identify possible changes. Results show that climate change is projected to have a significant negative impact in wine quality by increased dryness and cumulative thermal effects during growing seasons in Southern European regions (e.g. Portugal, Spain and Italy). These changes represent an important constraint to grapevine growth and development, making crucial adaptation/mitigation strategies to be adopted. On the other hand, regions of western and central Europe (e.g. southern Britain, northern France and Germany) will benefit from this scenario both in wine quality, and in new potential areas for viticulture. This approach provides a macro-characterization of European areas where grapevines may preferentially grow, as well as their projected changes, and is thus a valuable tool for viticultural zoning in a changing climate.

Quali cantine perle strade del vino

Tutte le cantine possono aprirsi al pubblico? Evidentemente si, nessuno può impedire ad un produttore di accogliere i turisti.
Tutte le cantine possono far parte delle Strade del vino? No, perché la Strada del vino mette in gioco la reputazione della denominazione di origine alla quale è legata e le possibilità di sviluppo economico di un intero territorio.

Proposal of a procedure for sensory characterisation of wines from different subareas of a same D.O.C. (V.Q.P.R.D.)

In the course of the present work, which is the first part of a study on the “characterization of Barbera dell’Oltrepo Pavese D.O.C.” 30 wines Barbera from 1993 vintage have been compared only regarding their sensory characteristics. An unstructured scale card, composed by 15 descriptors have been used.

Low and zero alcohol “wines”: impact of different dealcoholization processes on phenol profile and health benefits

Consumers’ demand for non-alcoholic wine has notably increased in the last years: this trend is a consequence of a growing interest in more healthy habits, and as a response to higher alcohol levels in wine due to climate change. In addition, drinking limitations due to physiological/pathological conditions (e.g., pregnancy, diabetes, hepatic disorders), driving regulations, ethical/religious considerations, and high import taxes on alcoholic beverages have positively influenced this marked (us$ 1.6 billion in 2021). International organisation of vine and wine (OIV) established that alcohol content defining wines must not be less than 8.5% vol, (OIV, 2017).
