The Four Roses 100th Anniversary Limited Edition Single Barrel Bourbon will be released in early April just in time for the Kentucky Derby (May 1). It is 17-years-old and will be bottled at barrel strength (55% ABV) and non-chill filtered. They will produce only about 2,300 bottles to be distributed nationally in markets where Four Roses is currently available.
