Spatial Analysis of Climate in Winegrape Growing Regions in Portugal

Abstract

Spatial climate data at a 1 km resolution has allowed for a comprehensive mapping and assessment of viticulture DOs regions in Portugal. Overall the 50 regions and sub-regions in Portugal range from just over 1200 GDD in the Vinho Verde to just over 2300 GDD in Alentejo with 34% of the wine producing areas falling in a Region II, 28% a Region III and 30% a Region IV on the Winkler classification system. On the Huglin Index the sub-regions range from just over 1600 to nearly 2700, representing HI climate types from Very Cool to Very Warm. For the GST index the sub-regions have a range from 15.7ºC to 20.7ºC, representing Cool, Intermediate and Hot climate maturity suitability on the GST. However, the results show that the spatial variability of climate within the regions, can be significant, with some regions representing as many as five climate classes suitable for viticulture. The results show how important it is to develop within region assessments of climate suitability for viticulture. Finally the diversity of climate types suitable for viticulture found in the Portuguese Wine Regions shows the broad range of wine styles that can be produced in the country.

Simulating the impact of climate change on viticultural systems in various European vineyards

Aim: Global climate change affects regional climates and hold implications for wine growing regions worldwide (Jones, 2007, 2015; van Leeuwen and Darriet, 2016). The prospect of 21st century climate change consequently is one of the major challenges facing the wine industry (Keller, 2010).

METAPIWI: unveiling the role of microbial communities in PIWI grapes for sustainable winemaking

The METAPIWI project advances viticulture research by examining microbial communities in PIWI (fungus-resistant) grapevines compared to traditional Vitis vinifera. It investigates how these microbes influence spontaneous fermentation and the production of distinct metabolites and aromas.

Mineral-wine profile and AI: wine authentication and identification

Enhancing the mineral wine profile: from authentication to identification by artificial intelligence for enhanced security. Analysis of a wine’s mineral concentration profile provides a distinctive fingerprint for each cuvée. Unlike organic profiles, this identification signature remains stable over time and can be deciphered using direct analysis by inductively coupled mass spectrometry (icp-ms).

EUGENOL AS QUALITY MARKER OF WINES AND SPIRITS FROM HYBRID VINES: IMPACT OF DIFFERENT WINEMAKING AND DISTILLATION PROCESSES

Eugenol, widely spread in various plants notably cloves, basil and bay, was identified too in wines from hybrid grapes without contact with oak wood. This aromatic molecule presents a strong spicy note of clove and also antifongic properties. Eugenol was described as an endogenous compound of Baco blanc, from the grapes to the spirits of Armagnac area. Moreover, this compound is a chemical marker of Baco blanc products quality.
Influences of harvest time and different winemaking processes (settling, use of enzymatic preparations, lees content and stock time before distillation) on Baco blanc wine eugenol contents were explored using a two-levels full factorial Design of Experiments (DoEs).

Partial rootzone drying (PRD): strategic irrigation management as viticultural tool affecting plant physiology and berry quality

Partial rootzone drying (PRD) is an irrigation management technique designed to reduce water use in grapevines without a decline in yield, thereby increasing water use efficiency (WUE). The principle of PRD is to keep part of the root system at a constant drying rate to produce soil derived signals to above-ground plant organs to induce a
