How much it will cost a grower or vintner to obtain Napa Green certification of sustainability practices depends on the program and certifier.
“The direct costs are minimal,” said Nate Weis, director of winemaking for Silver Oak and Twomey, which have production facilities and vineyards in Napa, Sonoma and Mendocino counties. “But the indirect costs, depending on what is already implemented, can be significant.”
The Duncan family is behind the iconic Silver Oak and Twomey wine brands. The organization has pursued third-party sustainability certification of its holdings through several groups, both known in the wine and construction businesses as well as not yet front of mind for many.
More than a dozen and a half Duncan family sites in those three counties were certified by the California Sustainable Winegrowing Alliance over a number of months. And its Napa Valley facilities also were certified last year under U.S. Green Building Council and Napa Green Winery programs.
After a two-year process, the Silver Oak Cellars main winery in the Oakville area of central Napa Valley last summer was certified at the highest level — platinum — under the council’s Existing Buildings: Operation and Maintenance designation that’s part of the Leadership in Environmental and Energy Design (LEED) rating system. That certification helped with the Napa Green Winery certification, Weis said.
“We had already done quite a bit to get ourselves up to snuff there,” he said.
Silver Oak’s winery in the Jimtown community of Sonoma County’s Alexander Valley is being outfitted to meet platinum-level LEED standards as the facility is readied for occupancy this summer. Elements of the Living Building Challenge certification by the Seattle-based International Living Building Institute also are being implemented.
PATHWAYS TO NAPA GREEN
For the Napa Green Land program for vineyards, the two avenues to certification are the Fish Friendly Farming program (fishfriendlyfarming.org) offered by the Napa-based California Land Stewardship Institute and level 2 of the LandSmart program (landsmart.org/vineyard) via the Napa Resource Conservation District. The LandSmart option was added last June.
Fish Friendly Farming started in Sonoma County in 1999 as a way for vineyard operators in the Russian River watershed to have verified that they were using best practices to protect listed fish. It expanded to Napa County in 2002 and now is used in Mendocino, Sonoma, Napa, Solano and El Dorado counties.
The fee for the Fish Friendly Farming program is $11 an acre, but grants cover all but $4 per acre of that, according to Napa Valley Vintners.
LandSmart was developed by resource conservation districts (RCDs) in Napa, Sonoma and Mendocino counties. Grants cover the cost to participate in the LandSmart program.
For vintners pursuing Napa Green Winery certification, the cost of a an integrated resource assessment by Sustainable Napa County project engineer Bill Bennett is roughly $1,000-plus, depending on winery size. Napa Valley Vintners offers some financial help with this, bringing the average out-of-pocket cost to $200–$400 per winery, depending on size, according to the trade association.
Bennett was a plant engineer for the Budweiser-focused brewery in Fairfield for three decades before joining Sustainable Napa County in 2010. The Napa-based Gasser Foundation started the organization in 2007 to promote energy and water conservation in Napa Valley.
NAVIGATING NAPA GREEN
ViewCraft of the Sonoma County community of Graton has been involved with Bay Area and wine industry sustainability programs since the early 1990s, even being involved with the crafting of the Code of Sustainable Winegrowing that became the heart of the CSWA program. Today, the company is helping wine businesses navigate the Napa Green programs. Part of that is help coordinating site visits required by the assessments.
