Joseph Phelps Vineyards, founded in 1973, created Insignia — California's first proprietary Bordeaux-style blend, first produced in 1974 and later named Wine Spectator's Wine of the Year. From its home estate in St. Helena's Spring Valley and vineyards across Napa, Phelps produces one of the valley's most consistently acclaimed portfolios; the winery was acquired by LVMH in 2022, extending its global reach.
