Exogenous dsRNA applications to identify novel candidate susceptibility genes to downy mildew

Trends already extended for more than 12 years show a decline in both consumption and international trade, particularly in volume. However, there are also positive signs in several categories of wine, segments and markets, as well as a better trend in terms of value. How are these trends affecting wine producers and distributors? Are they short or long term? do they mean radical and permanent changes to which a way of adaptation has to be found or are they just temporary changes that may only require some calm? How are companies adapting to these new trends? Which are their effects on wine regions?

Oxygen management in wine is one of the most significant challenging issues for winemakers.

This study explores the dynamics of maintaining aromatic elegance in a challenging oenological landscape by investigating the intraspecific variability of O. oeni in response to OIV-approved organic acid additions.

Nitrogen (N) fertilizer is important for grape growth and the quality of wine. It is essential to address the mismatch between N application and wine composition. Cabernet Gernischt (Vitis vinifera L.), as one of the main wine-grape cultivars in China, was introduced to Yantai wine region in 1892. This grape cultivar is traditionally used for quality dry red wine with fruit, spices aroma, ruby red and full-bodied wines. In order to regulate vine growth and improve grape and wine quality, Cabernet Gernischt grapevines were subjected to decreased levels of N treatments, compared to normal N supply treatment, during grape growing seasons of 2019 and 2020.

Anthocyanin profiling remains essential for assessing red grape quality and predicting wine color stability. However, traditional HPLC-based methods are time-consuming and impractical for routine vineyard maturity monitoring.
