The Sonoma County Harvest Fair serves as a vibrant celebration of the region's agricultural, industrial, and recreational producers. Since its establishment in 1975, it has evolved into a beloved annual event, attracting both local residents and international visitors. The fair has gained prominence as a premier regional wine judging competition, showcasing the exceptional quality of Sonoma County's wineries, restaurants, and farms.

At the heart of the Harvest Fair lies the Professional Wine Competition, a rigorous three-day event that draws expert judges from across the United States. These judges, including renowned wine writers, institutional buyers, and culinary professionals, evaluate over 900 wines, all crafted from Sonoma County grapes. The sweepstakes award winners earn significant local and national recognition, often citing this accolade as a career highlight.

Despite its national acclaim, the Harvest Fair maintains a strong local identity. The majority of competition exhibits are exclusively open to Sonoma County residents, and the food vendors and craftspeople are primarily local. This commitment to local participation ensures an authentic representation of the region's unique culture and offerings.

The Sonoma County Harvest Fair stands as a signature event, highlighting the extraordinary wine, food, and agricultural bounty of the region.
