Winters are cold sometimes very severe ( -15 °C) with snow. This intense cold affects the following spring and reduces the risk of vine diseases such as
Downy Mildew (plasmopara viticola) : parasitic fungus, it grows on all herbaceous organs (leaves , flowers, young berries ) particularly in humid or hot springs. It can cause crop losses and quality problems vines and weakens stocks.
powdery mildewand therefore the number of vine treatments. Snow layer helps protect the plants’ roots against the cold weather. In spring, slow snowmelt recharges the soil’s water reserves.
Powdery Mildew (Uncinula necator) : : a fungal, external parasite it grows as a gray and dusty felting on the upper surface of the leaves and young clusters. It can cause yield losses and quality problems with vines and weakens stocks.
With higher temperatures interspersed with a few intense rainy intervals, spring is an important period for the winegrower. The growth of the vineyard and indication of potential production is maintained and protected against the possible development of disease.
Hot and dry, vine growth ceases encouraging the
veraison. The vines concentrate their efforts in the production of quality grapes.
Veraison : period during which the grapes change colour - from green to red for red varietals, or from green to yellow to white varieties.
Sunny with mild temperatures and a little rain, it is the optimum period for the winemaker who oversees the harvest - the result of a whole year's work.
