Classification of the wine-growing environment of Central Mancha (Spain). First works

Detailed geological analyses of a plot belonging to the « AOC Gaillac » area have been carried out. This plot belongs to the left bank terraces of the Tarn River which coinciding with one of the three main terroirs of the AOC area. It is localised on the rissian-aged (≈ 200 000 yrs B.P.)

Nowadays the use of non-Saccharomyces as starters of alcoholic fermentation (AF) has increased because of the modulation of the organoleptic profile of wines

Recent decades have witnessed an evolving trend of diverse product types, improved quality, and green, low-carbon, and sustainable development in chinese wine market. A quality evaluation system, namely, with a dual orientation of “flavor compounds” and “sensory evaluation” is used as guidance for winemaking innovation in China.

The Spotted lanternfly (SLF), first detected in the U.S. in 2014, is an invasive phloem-feeding planthopper that poses a growing threat to grape and wine production in the U.S. In Pennsylvania, where it was first detected, reductions in grapevine production and fruit quality have been reported by commercial growers. Recent advances have begun to elucidate how SLF affects grapevine physiology and resource allocation, but no research has identified how SLF affects wine chemical composition and quality. Documented reductions in fruit sugar allocation due to heavy SLF phloem-feeding may have downstream effects on wine fermentation dynamics. Additionally, secondary metabolic responses stimulated by SLF may also influence berry chemical composition. The present study investigated SLF-mediated effects on wine composition through analysis of the volatile composition of wines produced from white- and red-fruited varieties of different Vitis parentage (e.g., Vitis vinifera vs. interspecific hybrids) following prolonged exposure to adult SLF phloem-feeding.

The habit of regular, moderate wine consumption, particularly with meals, is associated with protective effects from coronary heart disease. Epidemiological studies looking at myocardial protection/recovery focus mainly on the effects of red wine due to its high content in antioxidants, especially polyphenols. In several previous studies, conducted in our laboratory, we have concentrated on the effects of moderate consumption of white wine, by experimental animals (rats), gaining a significant experience in technical and procedural challenges. The scientific literature, and our past experience, suggests that rats are resilient towards consumption of full bodied, barrique red wines.
