Organic & Sustainable Practices

As of July, 2017, Ridge will have received organic certification for a collective 315 acres of vines at our Monte Bello, Lytton Springs, Geyserville, and East Bench vineyards. In addition to organic farming, we engage in a variety of other sustainable farming practices, including:

Compost
Each year, at both our wineries, we compost all our grape stems and pomace (fermented skins and seeds), along with our neighbors’ horse manure and other amendments such as organically sourced lime and gypsum. Composted for a year, this “black gold” is spread on our vineyards after harvest and helps feed our soil, which in turn feeds our vines.

Cover Crops
We use several different cover crops depending on our goals for each vineyard block. These include soil-building legume and grass mixes that add just enough nitrogen and organic matter to keep the vines healthy; insectary plantings to increase the population of beneficial insects; grasses and clovers for erosion control; and deep-rooted perennial grasses to control vine vigor in excessively fertile soils.

Water Conservation
We look to conserve water in a variety of ways. One way is by monitoring our vineyards at the vine level with the latest sensor technology to make sure that any irrigations we do are necessary. The sensors measure the sap-flow of individual vines, which provides us very specific data about their water needs. In addition, we recycle our winery grey water onsite so that it can be used for irrigation, if needed.

Integrated Pest Management (IPM)
We use IPM practices for insect and disease management. IPM is a systems approach to pests and diseases that combines a wide array of farming practices, with careful monitoring of pests and their natural enemies to prevent crop damage. An important overall goal of IPM is to reduce or eliminate use of both organic and synthetic pesticides. However, when the use of such materials is required, the proper timing of application, using IPM standards, can increase their efficacy and, therefore, provide an alternate route to minimizing applications.

Insects
Instead of spraying to control vine-damaging spider mites, we use beneficial insects to reduce their populations to insignificant levels. Careful monitoring of the mites, along with inundating the vineyard with the pest’s natural enemies, means we don’t have to apply broad-spectrum insecticides, which can potentially harm beneficial insects. This program has been so successful in some of our locations that we now have overwintering populations of the predatory insects large enough to negate any need for supplemental releases in the summer.

Birds
We use raptor roosts and bird boxes to help with insect and rodent control. This includes larger boxes for barn owls and smaller ones for bluebirds. Every winter after the birds have migrated south, we maintain and clean the boxes to ensure their use by wildlife the following season.

Vine Balance
We constantly work toward achieving vine balance, essential to producing flavorful wines of distinction and longevity. In some scenarios, this means removing excess fruit in order to create ideal ripening dynamics within the berries. In other situations, water may need to be applied to sustain the otherwise parched and stressed plants. Ultimately, balance is assessed on a vine-by-vine basis in order to meet our high standards for fruit quality. This philosophy is especially useful in our mixed variety plantings at Lytton Springs and Geyserville, as well as in the mountainous terrain at Monte Bello, where growth patterns can vary dramatically within a matter of feet.

Education
Our commitment to sustainable farming leads to our involvement in several organizations that foster new ideas about agriculture and environmental stewardship. We have participated in an agroecology diversity project with UC Berkeley, which will evaluate the use of cover crops and hedgerows to promote beneficial insects. The non-profit Vineyard Team, working toward sustainability in wine grapes, is collaborating with us on a cover crop trial of various clovers to assess their effectiveness in attracting beneficial insects.

In light of these contributions, Ridge has been recognized by the United States House of Representatives and the California State Legislature for excellence in water quality improvement and environmental stewardship.
