Trader Joe's has built a cult following for its interesting array of snacks, frozen finds, and unique limited-time offerings. Only a few of its wine brands exceed $50, and the store's top-tier private label caps at $20. The supermarket chain sources from around 70 different vineyards across Northern California, including Sonoma County, Napa, Mendocino, Southern Sonoma County, Marin, and Solano County. Trader Joe's wine experts taste every new vintage and reapprove a vintage each year before it hits shelves to ensure you're getting the best wine. We selected eight wine brands that are popular with shoppers, social media fans, and the Trader Joe's Wine Club podcast.
