Our goal in the vineyard is to maximize expression of terroir through maximum quality grapes. We achieve this goal through a mix of traditional practices, proprietary management practices, and selective use of technology. Windy Oaks Estate vineyard uses a VSP bilateral cordon system, with three double foliage wires, to provide maximum light and air flow for the grapes during their all-important growing season, from March through October. We personally work on and/or closely supervise the training, pruning, summer maintenance, and harvesting of the grapes. Our goal is to achieve expression of terroir through healthy grapes that have had substantial exposure to light and air, with maximum hang time to ensure optimum flavor and complexity.
The growing of premium grapes is a constant struggle between ensuring healthy growth, yet not so lush that the leaves and unwelcome growth overshadow the grapes. This struggle is what defines many of the activities carried out during the year. The following seasonal outline highlights the Windy Oaks Estate vineyard activities.
Pruning typically begins in January and lasts through March. Good pruning is critical to the vines, as this is what determines the spur position to ensure proper growth and spacing of the shoots for that year. We have developed a proprietary pruning approach that involves three separate passes through the vineyard over a 2½-month period. We have found that this helps ensure even fruit-set and crop load. Bud break usually appears in early March. Removal of suckers (those growths below the cordon wire) starts at this time and continues throughout the growing season. This is important as it ensures that this unwanted growth does not detract from the growth of the spurs above the cordon wire.
Sunshine and fog: sunny daytime temperatures in the low 70s, and at night the coastal fog rolls in and the temp is usually in the low 50s. In most years, there will be very little or no rain from now until November.
In April and May, the vigorously growing spurs are monitored to ensure that only two shoots extend from each spur. This process ensures that the growing grape vines will have maximum exposure to light and air. To prevent mildew during this all-important growing season, we spray the vines every couple of weeks with stylet oil (an organic product) or similar products. These low impact products are applied with a specialized venturi sprayer.
When the cordon spurs reach about 18 inches, we begin to tuck them in the appropriate wires. During this time, we usually weed-whack in the vine rows to control in-row weed growth, and mow our permanent cover crop between rows.
By late July, the canopy is fully extended up the wires and leaf-thinning begins. A group of trained workers goes through the entire vineyard and pulls leaves in strategic places. Again, the purpose of this is to ensure maximum exposure to light and air.
In mid-August, near veraison, the vines are netted. Although it is an arduous and expensive process, and it covers the vines at their prettiest time of the year, netting is crucial to protect the maturing grapes from birds. The nets are left on until harvest.
Beginning in mid-September, we start to sample the sugar content (brix), acidity and pH of the grapes. While we regularly check these numbers, our key indicator of ripeness is the physiological ripeness of the grapes, particularly seeds and stems.
Depending on autumn warmth, harvest occurs at any time between early and late October. Our four-acre vineyard in nearby Aptos is usually the first to ripen, and the earlier ripening sections of our Corralitos vineyard soon follow it. Typically, the chardonnay grapes ripen in the middle of the pinot ripening, and they are picked and processed in one day. We harvest each section of the vineyards separately, and keep them separate in bin and barrel.
