The characteristics of strong territorial brands: the case of Champagne

Temperature and yeast nutrition profoundly impact wine quality and sensory attributes by modulating yeast aroma production and release during fermentation. While temperature and nitrogen’s individual effects are well-studied, their combined influence, including nutrient type and addition timing, remains underexplored. hence, this study aimed to investigate the simultaneous effects of these factors on fermentation kinetics, aroma production and sensory profile, particularly in a Chardonnay wine production selected as a quite aromatically neutral base.

La zonazione viticola rappresenta un importante strumento di indagine per valutare e interpretare le potenzialità produttive e qualitative di un territorio. Con l’obiettivo di studiare come l’ambiente influisca sulla qualità dell’uva nell’areale di Brisighella, sono stati monitorati, nelle annate 2007, 2008 e 2009, 14 vigneti per la varietà Albana e 38 per la varietà Sangiovese, rappresentativi di una area vitata di circa 1000 ha.

Berry texture and berry skin mechanical properties have high agronomic importance, related to quality and marketing requirements of wine, table and raisin grapes.

Air temperature is arguably one of the most decisive factors for winegrape varieties developmental cycle, ripening potential and yield.

Currently, climate change represents one of the major issues for the wine sector. The increasing temperature already recorded and expected in the upcoming years reduce the vegetative cycle of the grape varieties planted in Bordeaux area, affecting the physicochemical parameters of grapes and consequently, the quality of wine. From a sensory point of view, the attenuation of the fresh fruity character in some varietals is accompanied by the accentuation of dried-fruit notes [1]. As a new adaptive and ecological strategy on global warming, some winegrowers have initiated changes in the Bordeaux blend of vine varieties using late-ripening grape varieties [2].
