Coombsville wines to know

Since becoming an official American Viticulture Area in 2011, Coombsville has taken off with its potential for wines with elegance.

What does that mean? Well, the valley's bay influence means it's a lot cooler than most of the rest of Napa Valley which means longer hang time and slower ripening. The result is wines with fresher fruit flavors (like floral "blueberry" notes in the Cabernet), more acidity and tartness, and lower potential alcohol.

You'll find Cabernet Sauvignon and the full spectrum of Bordeaux varieties here including Merlot, Petit Verdot, Cabernet Franc, Carménère, and Malbec. Additionally, due to its proximity to the bay, there's great Sauvignon Blanc, Chardonnay, and even rosé!

Coombsville terroir

The keen highlight of terroir in Coombsville is the marine layer of clouds and fog that lowers temperatures across the AVA. The fog layer can alter temperatures by 10°F compared to the rest of the valley.

A couple of soils types to note:

There's a substantial amount of volcanic ash settled in the valley from Mt. George which gives wines rich floral aromas.

Gravelly loams and rocky volcanic soils are typically on the knolls in Coombsville. These tend to be used for Cabernet vineyards and give wines a refined, earthy, pencil-lead aromas.
