Due to climate change, adaptations are needed in the winemaking process. Adjusting harvest dates according to grape ripening is a new challenge for professionals. In Europe, the heat waves and the drought have forced professionals to bring forward the harvest date.

What are the consequences of climate change on ripening? What is the link with wine aromas? What are the new strategies to adapt viticulture to these changes?

This week, we offer a few articles and proceedings from our 3 media (OENO One, IVES Technical Reviews and IVES Conference Series) to document you on these current topics.


Climate change projections for UK viticulture to 2040: a focus on improving suitability for Pinot noir.

Between 1981–2000 and 1999–2018, growing season average temperatures (GST) in the main UK viticulture regions have warmed ~1.0 °C and are now more reliably > 14.0°C […]

Performing sequential harvests based on berry sugar accumulation (mg/berry) to obtain specific wine sensory profiles

This study aimed to investigate the possible existence of reproducible aromatic red wine styles, focusing on fresh fruit aromas and mature fruit aromas (i.e., with dark, jammy fruit characteristics) and taking into account both vintage and vineyard […]

Aromatic maturity is a cornerstone of terroir expression in red wine

Harvesting grapes at adequate maturity is key to the production of high-quality red wines. Viticulturists, enologists, and wine makers define several types of maturity, including physiological maturity, technological maturity, phenolic maturity, and aromatic maturity […]

IVES Technical Reviews

Viticulture in a changing climate: solutions exist.

Grape growers have always cultivated vineyards in challenging environments, adapting their practices to sometimes very difficult local conditions. Climate change, as a new player, is modifying the terroirs’ characteristics rapidly and irremediably, giving viticulturalists major new challenges to face […]

Forcing vine regrowth: a new technique to delay grape ripening until a cooler period.

One of the most important climate change-related effects on wine grapes is the advance in harvest period. A strategy to counteract this effect consists in postponing berry ripening until the conditions are cooler […]

Principles of vineyard establishment and strategies to delay ripening under a warming climate.

Some viticultural strategies may offer a natural solution to mitigate the negative effects of global warming in viticulture. Decisions concerning vineyard topography variables […]

Effect of grape harvest time on the metabolomic profile of ribolla gialla monovarietal sparkling wines.

The timing of grape harvest is crucial factor to be considered in the winemaking process, as delayed harvest increases the content of varietal aromas, esters, aldehydes, and alcohols, while concentration of green odor related compounds decreases […]

Influence of pre-harvest elicitors treatment during ripening period on phenolic composition in Monastrell grapes.

Phenolic compounds are very importants in crop plants, which is why there have been the subject of a large number of studies […]

Harvest dates – temperature relationships and thermal requirements of winegrape varieties in Greece: observed and future climate responses.

Harvest dates showed negative trends in six out of eight cases (four cases statistically significant) while in two areas (Crete and Pyrgos) harvest occurs later […]
