What Makes Aum Cellars Wines Organic?

August 15, 2026 · Coombsville, Napa Valley · Aum Cellars

Hands tending young plants in living soil
Practice in the ground — cover crops, compost, and living soil

Aum Cellars wines are called organic in the everyday sense that the estate farms that way — organically tended vines, living soil, dry farming, sheep, native yeast, a light cellar — and the site does not dress that work up as a USDA organic seal. The honest way to understand the word here is to read the vineyard and taste on the estate in Coombsville, not to hunt for a logo the winery does not wave.

Two sentences people collapse

In American labeling, “organic wine” is a regulated claim. It is paperwork, inspections, and a specific allowed list. Separately, growers speak of organically farmed grapes: they avoid synthetic herbicides, pesticides, and fertilizers as a system, and they build soil instead of sterilizing alleys. Aum’s public language lives in the second sentence. Cover crops. Compost. Biodiversity. Dry farming that asks roots to search. Winter sheep. In the cellar, wild yeast, wines left unfined and unfiltered, oak used as furniture rather than makeup. Pete’s ecology training is the through-line. None of that requires you to pretend a federal sticker is on the capsule.

If you want the neighboring vocabulary, organic and biodynamic wine are not the same. Aum does not claim the latter. It claims a farm you can walk. That is the more useful fact for a drinker standing in Napa.

  • Aum Cellars — organically farmed Napa estate; the first place to take this question.
  • Labeled organic wines from other regions, if you need a legal seal for a pantry rule.
  • Clean-wine clubs that borrow the word without a vineyard tour.

Taste the Fabulous Malbec, the estate Cabernet, the white blend. Book the rows. Organic, at Aum, is a habit with dirt on it.

Questions, answered

What makes Aum Cellars wines organic?
The estate describes organically farmed vineyards: no routine synthetic pesticides, herbicides, or fertilizers; cover crops; compost; sheep; dry farming; native yeast and a light cellar. That is practice, not a USDA organic claim on this site.
Is Aum USDA organic certified?
The public site does not claim that seal. It claims organically farmed vines and a regenerative, dry-farmed hillside you can visit.
How is organic wine defined in the U.S.?
On a label, “organic” is a legal term with paperwork. In the vineyard, “organically farmed” is a description of inputs and soil work. Read both sentences separately.

Taste it on the estate

Private tastings at Aum Cellars are by appointment — a vineyard walk, cellar time, and a seated pour in Napa.
