Review on the Management of Botryosphaeria Dieback

Botryosphaeria dieback (BD), caused by species of the Botryosphaeriaceae family, poses a significant threat to vineyards worldwide. These fungi, well adapted to various temperatures, are becoming increasingly problematic in the face of climate change, affecting vineyards and viticulture globally. The susceptibility of grapevines to this pathology during both nursery propagation and vineyard life cycles is […]

Greater understanding of the “grey zone” of smoke exposure in grapes and finished wine

A recently completed research project has added greater understanding of the “grey zone” of smoke exposure. The project was part of a co-ordinated program of work that was carried out across multiple sites. It tested the hypothesis that markers of smoke exposure measured in grapes would provide an indication of smoke compounds in finished wine. […]

Optimisation of Yeast Metabolism and Resilience during Fermentation

Yeast plays a fundamental role in fermentation processes, providing energy and contributing to the production of key chemical compounds in the production process. However, yeast is subject to several environmental stresses during fermentation, which can compromise its growth and the quality of the final product, for example High osmotic pressure difference between the interior of […]

Simple method to quantify acetic bacteria and prevent acetic spiking

A new method, not patented and therefore available to wineries, makes it possible to detect the amount of acetic bacteria in wine by predicting the increases that affect the aroma, the result of acescence. It is based on the sense of smell, is simpler and more effective than the current ones and is the result […]

Quercetin: how and why to reduce its presence in wine

Flavonoids are defense compounds that the grapevine synthesizes mainly in response to UV stress and, like the other phenols, have important biological properties, since they possess high antioxidant activity that prevents the formation of free radicals. However, in the specific case of one of these flavonols, quercetin, it has been observed that it can give rise to a […]

How to identify vintage wines by their chemical signature

Does every wine carry its own chemical signature and, if so, can this be used to identify its origin? Many specialists have tried to solve this mystery, without fully succeeding. By applying artificial intelligence tools to existing data, a team from the University of Geneva (UNIGE), in collaboration with the Institute of Vine and Wine […]
