We define biodiversity as the biological wealth of an ecosystem and the balance of its populations that provide stability and resistance to extreme factors. It is important to consider that within the species that inhabit a soil, microorganisms have a fundamental role. This is why we have launched the biodiversity ranking, an index that measures the microbial community of the vineyards. One of the wineries that appear in the US Top 10 is Silver Oak. Do you want to meet them?


A constantly growing winery

The origin of Silver Oak dates back to 1972 when Duncan family founded the winery. Their main goal has been always growing and making Cabernet Sauvignon in the Alexander and Napa Valley. But there are no barriers for this family that founded another winery in 1999, Twomey Cellars. This time, the focus was growing another grape varieties like Merlot, Pinot noir and Sauvignon blanc.

Little by little, the winery has growth to obtain large extensions of vineyards in several states. Currently, they farm close to 500 acres throughout Napa, Sonoma, and Mendocino in California, and Dundee in Oregon. They know that the continuous improvement is the only way: “We have yet to make our best bottle of wine.”


The value of soil

All farming in this cellar is focused on sustainability. For them, the value of their land is in the site, the geologic history, and microclimate, but of course in the soil, the support of the grapevines. “Its health cannot be ignored, so many of our decisions surround building structure, health, biodiversity, and nutrition.” For Sliver Oak the recipe to keep such a high biodiversity is to listen to what each vineyard is telling them and they get this information from the soil and plant analyses.

They discovered WineSeq® during Fruition Sciences’ Vintage Report 2016, an event in which wine and science converge to discuss the innovations in the wine industry. They found the tool an interesting and helpful one in assessing soil health, and now, they are able to measure its microbial biodiversity. “We’re very proud of this acknowledgment that our practices are achieving some of our end goals.” According to their philosophy, they think they have never get the top, so for them, there are always a lot more to do, though.
