Furthur is a Kentucky-bottled whiskey label with a Merry Pranksters spirit: proceeds support the Furthur Down the Road Foundation, the nonprofit founded by Ken Kesey's daughter-in-law and named for the famous psychedelic bus. The range includes a three-year small batch straight rye and the Four Seasons series of seasonal bourbon and rye releases, each with its own label artwork and a profile matched to the time of year. Furthur bottles at 101 proof, a nod to the highway, and sources its whiskey from established distilleries. Shop Furthur at Chips Liquor with fast shipping.
