Spurs are thinned to one shoot per bud and two buds per spur with an optimum number of shoots per cordon foot appropriate for that variety. Weak and non-fruiting shoots and suckers sprouting from the head are removed.
Fertility: When making nutrient application decisions, leaf petiole analysis results are used as a guide. Vine vigor, fruit quality, wine quality, leaf symptoms, and vineyard history are factored into the decision. Site specific nutrient applications are made.
We use a pressure bomb throughout the irrigation season to measure the moisture content of the vines to determine our irrigation requirements.
We partner with a PCA (pest control agency) that monitors our vineyard weekly. We keep a written record of what is found. Our control decisions are not only based on economic thresholds of destructive pests such as mites and leafhoppers but on the population of mite and leafhopper predators.
Winemaking & Viticulture
With the help of the winemaker we adjust our viticultural practices by determining which contribute positively or negatively to wine quality.
We are aware of the main watershed and tributary watersheds that our vineyard operations are located in. We manage the vineyard operations to conserve water and protect water quality by using such practices as cover cropping, buffer strips and other erosion control measures that protect riparian areas and aquatic habitats, particularly from sedimentation.
We track the amount of fuel used in the vineyard, and the results are used as part of an overall energy monitoring and conservation plan. We use some alternative fuel sources in the vineyard.
Some of the items we recycle include batteries, tractor tires, scrap metal, cardboard, oil and oil filters.
We conduct monthly employee safety and training meetings as the season progresses and safety issues change. The meetings are documented with dates and attendance. We also have a third party audit our complete safety program at least once per year.
We use a combination of seeding or an approved anti-dust material on unpaved roads. Speeds and travel are restricted on and around the operation.
