Molecular characterization of a variegated grapevine mutant cv Bruce’s Sport

The global consumption of wine has undergone significant changes after several years of covid-19, which was the beginning of a global crisis of the current century. This pushed some people to start looking for comfort and security as they felt that the world around them was losing these benefits. In most cases, this has led to them to idea of rethinking their lives in an attempt to live better or continuing to stay true to their habits and lifestyles despite the pressure of changes. Alcohol in any form is a part of these reactions, leading to increased consumption in the early stages of a crisis, particularly in relation to anxiety.

Aims: This work summarizes some of the upmost recent studies and valorization strategies concerning the Prosecco wine production area. After the geographical denomination Prosecco (DO) was strongly reformed in 2009, the newborn DOCG (controlled and guaranteed DO) and DOC (controlled DO) areas have required different and specific strategies to promote and protect the value of their production.

Il mondo del vino si è accorto che per la sua comprensione, valorizzazione e promozione è fondamentale conoscere le ragioni geologiche del vino, valutare il suo impatto sul paesaggio e acquisire il suo valore emozionale.

A new process for vacuum evaporation was developed where evaporation takes place near the inner surface of a vortex produced by a rotor submerged in the liquid. Contrary to the state of the art the Vortex rotor process does not need a vacuum vessel but the rotating liquid creates a geometrically stable low pressure void surrounded by a vortex stabilized by the equilibrium between centrifugal forces and the pressure difference. First tests with water and sugar solutions at concentrations similar to grape must were conducted to verify the theoretical predictions, test the performance under different conditions and study the effect of various process parameters (Rösti et al 2015).

Accentuated cut edges (ACE) is a novel grape crushing technique used sequentially after a conventional crusher to increase the extraction rate and content of polyphenolics, as shown for Pinot noir wine. This inspired us to apply the technique during Shiraz and Sauvignon blanc winemaking, primarily to assess its impact on the extraction of varietal thiol precursors in grape must/juice and formation of varietal thiols in the resultant wines
