Sonoma County Conjunctive Labeling

Definition of Conjunctive Labeling:¬†Labeling of a wine to show both region and sub-region (AVA) of origin. In our case, it refers to the inclusion of “Sonoma County” on the label of all Sonoma County wines along with any AVA designation.


  • To build brand equity for Sonoma County wines and preserve and strengthen Sonoma County’s position as a recognized world-class wine region
  • To increase sales of wines produced from Sonoma County grapes.
  • To increase recognition for every AVA within Sonoma County, both well-known and less familiar, and ensure that consumers understand where they are.

Quick Facts

What it means:

  • ALL wine produced from a Sonoma County AVA must also include “Sonoma County” on the label
  • Wineries have creative flexibility on the font, size, and location of “Sonoma County” within their label design
  • There is a three year phase-in period, so vintners have until January 1, 2014 to comply. The law officially goes into effect January 1, 2011
  • “Sonoma County” must appear on the label that is submitted as the legal label for TTB approval
  • The law will be enforced by the ABC

What it does NOT mean:

  • “Sonoma County” does not need to appear on the label right above or below the AVA name. (See gallery at right for examples)
  • “Sonoma County” does not need to appear in the same font or size as the AVA name. The type does need to be 2mm or larger in size, as required by the TBB for any type on a label.
