“Gheo” per la vitivinicoltura: un progetto per la produzione dl vini dl alta qualità

Grape pomace is one of the main by-products generated after pressing in wine-making. It’s valorization through the extraction of bioactive compounds is the answer for the development of sustainable processes. Nevertheless, in the recovery of anthocyanins derivatives, the extraction stage continues to be a limiting step. The nature of the sample and the type of solvent determine the efficiency of the process

Wines exhibit profound chemical complexity which arise from a diverse array of compounds that contribute to its sensory profile.

In this video recording of the IVES science meeting 2023, Hans Reiner Schultz (Hochschule Geisenheim University, Germany) speaks about soil carbon changes and greenhouse gas emissions in vineyards – is the 4 per 1000 goal realistic?. This presentation is based on an original article accessible for free on OENO One.

The European geographical indication (GI) Brandy Italiano is exclusively reserved to brandy obtained in Italy from the distillation of wine from grapes grown and vinified in the national territory [1].

Nitrogen (N) is quite important nutrient in grapevine development and must quality, but under Mediterranean climatic conditions, available soil water (ASW) during grapevine development can also influence vigour and must quality. The aim was to determine the influence of soil nitrate (NO3-) availability on N foliar, yield, and must quality in vineyards with similar available water holding capacity (AWC). For this purpose, four cv. Tempranillo (Vitis vinifera L.) vineyards were selected. All of them are placed in Uruñuela municipality (La Rioja, Spain), separated less than 2.5 km and in a slope <1 %, in soils with similar soil chemistry properties and with similar rooting depth (ranging between 105 cm and 110 cm).
