Unexpected relationships between δ¹³C, water deficit, and wine grape performance

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.

Rootstocks have been used in most of the vineyards for over a century. This may seem to be a long period, but it represents only three successive plantations.

Like France, Hungary has many oak forests used for making barrels since many years. But if the differences between the woods of the North, the East and the South-West forests of France are well known, this is probably not the case of Hungarian forests. However taking into account the essential differences of climates and soils, differences must be significant and the general name “Hungarian oak” must not have any real meaning. We have studied precisely (determination of concentrations of volatile and non-volatile wood compounds, anatomical criteria, measurement of antioxidant capacity) of oaks collected from northeastern Hungary and others collected from the Danube valley in the northwest of the country.

In this work, we present a method based on very high spatial resolution (VHSR) aerial images acquired in the visible domain and that map soil surface diversity at the hillslope

AIM: Metabolomics in food science has been increasingly used over the last twenty years. Among the tools used for wine, qNMR has emerged as a powerful tool to discern wines based on environmental factors such as geographical origin, grape variety and vintage (Gougeon et al., 2019a).
