The Life of a Vine in July

The Life of a Vine in July

Not everybody is busy preparing a National Convention for over three hundred attendees at this time of the year. However, vineyard managers are already starting to shape up their rows of vines for the upcoming harvest for 2017. ย  Canopy Management The goal is to promote an optimal ripening of the berries for harvest. Complex decisions must be made and actions taken regarding leaf removal, vigor management, disease control, shoot thinning and shoot positioning. The goal is to achieve the perfect balance of shade, sunlight and air circulation around each grape bunch. In California, vineyard workers and tractors often make more than 20 passes through a single row of vines to achieve this goal of perfect ripeness. ย  The Life of a Vine in July ย  Soil Preparation After edging the vines, the top soil is tilled and mixed with the grass. The last rainfall of the summer here in the Napa Valley produced quite a bit of growth. This organic matter will be bring moisture and nutrients to the vines for their full development. ย  The Life of a Vine in July ย  Fruit Set and Leaf Thinning Once grapes begin their maturation process, then the fruit starts to set. This is when the grape flesh and skin tannins begin to develop. Unfortunately, this does not always occur evenly within clusters. Fruit that does not properly develop is pruned. Often called โ€œgreen harvesting,โ€ crop thinning refers to the dropping of unripe grape bunches that are not perfect and which may not be developing in an even pattern. They also address the excess leaves by taking out a portion of them, which directly applies shade to the berries. This will provide for better maturation and a better air flow to avoid rot with excess moisture as a result. ย  The 2015 Harvest Has Begun ย  Veraison Sometimes in mid-July or the beginning of August, all grape varieties will change in color. This period of grape pigment development is called veraison. Just like bud break, this step in the life-cycle of the vine can take several weeks, depending on the grape variety and the micro-environment of that particular vineyard site. Many vineyards have wide temperature swings, which vary as much as 30-40 degrees Fahrenheit between night and day. Californiaโ€™s warm weather promotes ripeness and sugar development in the grapes. The cooler, often fog-infused, nights help the grapes to retain acidity and freshness for balance. ย  The 2015 Harvest Has Begun ย  Currently, we are in good shape with excellent conditions across the state. There is plenty of reserve in the soil. Dry and warm conditions in California will advance the harvest by a couple weeks this season. ย  The Life of a Vine in July ย  There is indeed a lot of work to be done to prepare for the best harvest yet. Meet our newest assistant vineyard managers. They will attend to the vine and take care of every situation by leaps and bounds. ย  ย
