Biodynamic followers in viticulture and winemaking are growing rapidly. Part of the concept is to use the moon calendar when it is time to make important decisions like treatments in the vineyard, picking the fruits, racking or bottling the wine.
Some firmly believe the Moon phase has an impact on the quality of the fruit, the growth of the plant, the quality and expression of the wine or the sediments in suspension within the barrels.
Science is more on the side of the myth to the exception of the moonlight impact during night activities.
One thing is sure though, organic, biodynamic or common sense, if you take care of Mother Earth, you get the quality of fruit you deserve.
