Napa Valley is just 35 miles long and 5 miles wide, but for such a small place we have a rich history of being on the forefront of sustainability and environmental preservation. Back in 1968 Napa Valley was designated as the United States’ first ever agricultural preserve, ensuring that Napa Valley would be protected and preserved for generations to come. 

Today, everyone wants to be sustainable, but it can be hard to pinpoint what sustainability actually means – and who’s actually doing it well. That’s why the Napa Valley Vintners established Napa Green, which created the Napa Green Vineyard and Napa Green Winery certifications. That means that you can easily identify grape growers and wineries who’ve invested deeply in all aspects of sustainability, from energy and water efficiency to social equity and climate action.

There are more than 90 Napa Green Certified Wineries, representing 40% of all of the certified sustainable wineries in California, and 34% of all of the certified sustainable wineries in the United States.

In addition to Napa Green certification, here are a few other terms you might see:

Natural – Natural wine typically references low-intervention wine where no herbicides or pesticides are used in the vineyard, and no additives have been added in the winemaking process. Natural wines also tend to be unfiltered and have low or no sulfites to preserve the product as its bottle.

Organic – An organic listing on a wine label means one of two things: It’s either made from organically grown grapes, without any added sulfites, or it’s made from certified organically grown grapes, avoiding all synthetic pesticides.

Biodynamic – This technique is similar to organic farming in that it avoids synthetic chemicals, but it also views the vineyard as an entire ecosystem, observing factors such as astrological influences and lunar cycles. Biodynamic wines are also made without common manipulations such as yeast additions or acidity adjustments.

LEED certification – This certification indicates that the winery itself has been built and is operated in an ecologically sound manner. LEED (Leadership in Energy and Environmental Design) is the most widely used green building rating system in the world and recognizes five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, material selection, and indoor environmental quality.
