Wente Vineyards Announces 2019 Sustainability Report Card Ahead of Earth Day 
Fifth generation family winegrowers lead the way in innovative ethical practices and sustainability programming
LIVERMORE VALLEY, CA – April 19, 2019 – In honor of Earth Day on April 22, 2019 Wente Vineyards is proud to share an updated series of green initiatives and programming, all of which reflect the winery's longstanding (136 years and counting!) and ongoing commitment to sustainable winegrowing.

As of 2019, Wente Vineyards, America’s oldest, continuously operated family winery, is among only 2% of California WV CCSV Logowineries to have achieved the Certified California Sustainable Winegrowing (“CERTIFIED SUSTAINABLE”) designation for both its vineyard and winery. Any winegrowing operation hoping to attain the CERTIFIED SUSTAINABLE designation must meet a stringent set of criteria in order to preserve and protect their land, water, and air, but also demonstrate ethical leadership with how they treat their employees and local communities.  Wente Vineyards was one of 18 pilot wineries to achieve CERTIFIED SUSTAINABLE status in 2010, and beginning with the 2017 vintage, the winery will include the official CERTIFIED SUSTAINABLE logo (pictured right) on all packaging, in order to better communicate its practices to consumers and help create more demand for true sustainable wines.
The Wente family’s philosophy on sustainable practices dates back to 1883, when Carl H. Wente arrived in Livermore Valley and realized the only way to guarantee the next harvest (and the next ten after that) was to treat the land and the people who tend to it as responsibly as possible. Today, fifth generation winegrowers Karl & Niki Wente have wholeheartedly taken the baton, and recently upgraded the winery, vineyard and tasting rooms to meet (and exceed) their family’s CERTIFIED SUSTAINABLE-inspired goals. Recent additions to the sustainability ‘menu’ at Wente Vineyards include:
  • BlueMorph UV light system replaces a typically chemical/water-heavy rinse cycle during winery sanitation with a hot water wash followed by UV sanitation, saving roughly 150,000 gallons of water per year.
  • All water used in the production facility is re-used to drip irrigate the vineyards (and only when truly needed).
  • More than 10 million gallons of water used in the production facility are recycled/re-used to irrigate the vineyards or used for dust control, and an on-property water treatment pond contributes to the reclamation of all production water used in the winery’s facilities.
  • Roughly one third of the grape tonnage that is processed is spread back into the vineyards as part of soil management process. The grape pomace is repurposed for beneficial uses such as composting, which is incorporated in the vineyards to increase the level of organic matter, improving soil health and water retention.
  • Cover   crops   prevent   soil   erosion   during winter rains and provide a nourishing habitat for beneficial insects. Wente Vineyards’ cover crops are recycled into an organic fertilizer and soil enhancer used to create living soils, which renew themselves. Creative farming practices encourage bio-diversity in the vineyards, greatly minimizing the need for pest intervention. 
  • STARS Filtration Unit (Selective Tartrate Removal System), reduces energy load during the winery’s cold stabilization process which saves both energy and money (and vastly improves conditions for workers who no longer have to work in frigid temperatures!).
  • Incandescent and halogen light fixtures have been replaced with natural skylights and supplemental LED lights to improve energy efficiency.
  • In 2018, 77% of Wente Vineyards’ consumables waste was diverted from landfill and instead recycled by local partners.
  • Wente Family Estates cultivates native grasses and other beneficial flowering species that help maintain an ecological balance where pests are therefore naturally controlled. The Wente family also manages 1,600 acres of sustainable open range land not planted to vineyard, with 100 head of cattle providing grass management and soil fertilization.
  • Aero falconry is employed in partnership with a Master Falconer, making the vineyards a natural no-fly zone for starlings. Electronic squawk boxes are used as backup.
  • Owl boxes and raptor perches naturally control the vineyards' destructive starlings, gophers and ground squirrels.
  • On-site weather stations use UC Davis-developed mildew pressure models to pinpoint exactly where to spray, if at all. Environmentally friendly stylet oil (a combination of natural oils such as clove, black pepper and cinnamon) is used to smother mildew and control pests.
  • The award-winning Make Time™ initiative strengthens Wente Vineyards' long-standing pledge of creating a culture of balance for its employees. Updates inside the organization include:
    • Embodying Make Time Off (MTO): An additional paid time off offering to all of its nearly 700 employees to use on activities they enjoy with the people they care about.
    • Developing a Make Time Committee: A team of employees dedicated to ongoing nourishment of the Make Time culture, achieved through exploration and implementation of tools and skills offered to all employees and development of company events.
    • Instituting Make Time Mixers: Company-held social events, during business hours, to encourage coworker camaraderie and to refresh and recharge
  • The Wente Foundation for Arts Education’s mission is to provide support for arts education programs in the Livermore Valley and throughout Northern California. Under the leadership of its 5th generation President, Christine Wente, The Wente Foundation for Arts Education extends the Wente family’s legacy of leadership in the wine industry to the world of philanthropy by meeting a financial need and creating opportunities for talented students.
    • The Livermore Valley Winegrowers Foundation and The Wente Foundation for Arts Education work together to present the Livermore Valley Wine Auction, which has raised over $5 million for local organizations to raise funds to improve the quality of life for underserved local children.
    • Karl Wente created a small lot, limited edition wine, The Art of Giving, in support of the mission. With every bottle sold, 50% of the purchase price is donated directly to The Wente Foundation.
  • To communicate the importance of responsible farming to the consumer, the CERTIFIED SUSTAINABLE logo will be featured on all Wente Vineyards back labels from the 2017 vintage forward.
  • All Wente Vineyard tasting rooms are designated drop-off spots for Cork ReHarvest, a program focused on collecting and recycling use and surplus corks from wineries.
  • Wente Vineyards uses Century Olive Oil trees to produce Certified Sustainable oil, which come from an extensive tree-planting program, a testament to the Wente family’s tradition of commitment to sustainable agriculture.
Today, with the help of the forward-looking fifth generation, and the foundations of the generations before them. The Wente family remains a leader in ethical practices, producing high quality grapes and wine, protecting the environment and enhancing the communities in which they live and work by implementing sustainable winegrowing practices that are environmentally sound, socially equitable and economically viable. In short, Wente Vineyards continues to push the envelope in redefining how sustainability is measured.
