Fungus resistant grape varieties (FRGV or PIWI) offer many benefits such as less pesticide use or premium prices for enhanced sustainability. Still, winemakers are concerned about inferior wine qua...
Phenolic composition of grapes has an important impact on the final intrinsic quality of (red) wines. Wine taste, mouthfeel and colour are driven principally by phenolic compounds present in grapes...
For the production of quality sparkling wines, it is important to ensure the separation of the correct phenolic profiles of must fractions. Find out how UV-Visible spectroscopy, together with chemo...

During the ROUND TABLE #4 - Yeast, bacterial and plant resources for sustainable winemaking processes, held at Macrowine 2021 we had four interesting presentations from across the world
The main purpose of this project is to provide a better understanding of how the synthesis of these flavour-active compounds is modulated at genetic level, aiming to identify genes with specific fu...
Grape withering is an oenological post-harvest process used for production of reinforced and sweet wines. Drying can be carried out by keeping the ripe grape in traditional large, well-aired rooms ...

The aim was to characterize taste and mouthfeel properties of grapes elicited by the phenolic fraction (PF) of grape berries and establish relationships with chemical variables
Recording of the webinar held by Dominique Delteil
In this recording of the webinar held by Dominique Delteil (Delteil International Wine Consulting) topics covered are: the origin of gluconic acid, its importance as an indicator for optimal grape ...
