Techniques of delimitation in France

Wine is a widely consumed alcoholic beverage with a high commercial value. More specifically, the worldwide consumption of rosé wine has increased by 20% since 2002[1]. But because of its high commercial value, it can become a subject of fraud, and authenticity control is necessarily required. More than one hundred polyphenols have been recently quantified in various rosé wines [2]. They are key components defining color, taste and quality of wines. Their amount and composition depend on many different factors such as grape variety, winemaking and age of the wine. In this study, the influence of geographic origin of some rosé French wines was investigated. An original and very fast UPLC-QTOF-MS method was developed and used to predict the geographic origin authenticity of rosé wines.

Vines are one of the most pesticide-intensive crops in France, and reducing their use is a major challenge for both the environment and human health.

The development of off-flavours in wine distillates, particularly those associated with the tails fraction, is a key issue in the production of high-quality spirits.

Climate change has been influencing viticulture and changing wine profiles in the past years, and effects are expected to get worse.

Le terroir peut être défini comme un écosystème dans lequel la vigne interagit avec le climat et le sol et dont la résultante est le vin.
