Typology of Terroirs around the world

Following its approval in 2013 by Agroscope, Divico became the first interspecific grape variety in Switzerland with high resistance to downy mildew (Plasmopara viticola) and grey rot (Botrytis cinerea), and medium resistance to powdery mildew (Uncinula nectator). Extremely riche in color, Divico grapes showed great enological potential to different styles of wine. Quickly, many wine growers were interested in planting this promising variety. Many of its potential are to be explored in the coming years.

A good knowledge of the soil physicochemical properties, as well as its ability to retain and put the necessary water available to the plants, is essential when it comes at the design of an irrigation plan.

Supercritical carbon dioxide (sc-CO2) extraction is an environmentally friendly technology employed for bioactive compounds recovery from various natural sources and biomasses. The advantages of sc-co2 extraction include its selectivity, relatively mild operating conditions, which minimize the degradation of sensitive compounds, and the absence of potentially harmful organic solvents.

Aim: This work studies how successive O2 saturations affects the color and hydroxycinnamic
acids concentration in the absence and presence of laccase from B. cinerea with the aim of better understanding the browning processes.

Materials and methods: Grapes of Muscat of Alexandria were harvested and pressed with a vertical press to extract 60% of their juice. Aliquots of 30 mL of this must were placed in 60 mL flasks equipped with a pill (PreSens Precision Sensing GmbH) for measuring oxygen by luminescence (Nomasense TM O2 Trace Oxygen Analyzer).

Considering that „prevention requires information”, in 2007, the european education program wine in moderation (wim) started. The common message of responsible and only moderate wine consumption is implemented in each participating country, adapted to national circumstances. In germany, besides recruiting new wim members from the wine sector, the deutsche weinakademie focusses also on information and education of future wine makers and cellar men in professional schools. The seminars cover basic information about the existing legal framework (youth protecting law, drink driving laws, etc.), the self regulation code of conduct for commercial communications (advertising) of alcoholic beverages as well as the health effects of alcoholic beverages, and of wine in particular.
