Application of nitrogen forms such as nitrate, urea, and amino acids effects on leaf and berry physiology and wine quality

The mechanical strength or firmness of a fruit is considered an important parameter to characterize its state of maturity or conservation, as other parameters such as sugar level or color.

The concept of terroir is well established in the ‘old world’ wine industry but its use is still relatively new in New Zealand. Marlborough Sauvignon blanc has become a benchmark

During cold storage, grapes undergo changes that affect their visual, mechanical, and organoleptic properties, potentially impacting quality and negatively influencing consumer acceptance. Key parameters include uniform color, crunchiness, and flesh consistency. We evaluated the influence of two distinct packaging methods on the chromatic characteristics, hardness, and pedicel detachment resistance of fourteen new seedless white and red grape varieties during cold storage. These factors are crucial for maintaining the quality of the product and extending its shelf-life. The novel grape varieties were obtained through a breeding program at CREA-VE of Turi, Southern Italy.

Local climate characterization is fundamental in terroir description, yet global change perspectives raise questions about its feasibility, since temporal stability cannot be no more assumed for the forthcoming years.

Climate change, driven by greenhouse gas (GHG) emissions, is one of humanity’s most significant environmental challenges.
