A bourbon shelf essential. Four Roses Single Barrel is a 100-proof Kentucky Straight Bourbon, aged 7 to 9 years and bottled one barrel at a time, so each bottle brings a little personality of its own. Its signature OBSV recipe leans higher in rye, giving the bourbon a lively, spicy edge alongside ripe plum, cherry, pear, cocoa, vanilla and maple. Bold, balanced and beautifully smooth, it’s equally happy poured neat, over a big rock or into an Old Fashioned.
