We got good notes in the for Perrin & Fils “Les Sinards” Chateauneuf du Pape International herald tribune.

To maintain the practice of organic viticulture while protecting us from the grape-worm. We avoid the use of pesticides and chemicals. We attach containers to the vines which give off phéromones for 6 months.  As the male butterfly seeks the femal by the scent of pheromones, the continers that give off the scent make the female butterfly all the more difficult to find, which result in less incidence of mating in the vineyard.  The butterflies are dangerous for the vine, as their caterpillars feed off the leaves and cause marked decreased quality of the grapes, which are more prone to attack by fungi.

Once the cold weather begins to retreat in Winter and before the strong heat and drought of the Summer, we go through the vineyard and replace vines that have expired the year before. This is done in the March & April. Due to the advance average age, of our vines, we expect a mortality of about 2% of plants each year that, succumb to illness and/or age.  We remove then the dead stumps and remove the vine roots about 80cm in the ground.  We replant on “Selection Masale” regime.
