Bonny Doon Vineyard is a winery in Santa Cruz, California, that focuses on terroir wines. Founded by Randall Grahm in 1983, it is perhaps best known for its quirky labels, eccentric mix of grapes, and humorously-named wines—like its flagship wine, "Le Cigare Volant".[1][2] It was amongst the first Californian wineries to embrace Rhone varietals, and entered the national spotlight in 1989, after Grahm appeared on the cover of Wine Spectator as "The Rhone Ranger."[3]
