Mash Bill: 60/35/5 Corn/Rye/Malted barley

About: Four Roses uses two different mashbills and five different yeast strains to create 10 unique bourbon recipes. The OBSK mashbill consists of 60% corn, 35% rye, and 5% malted barley. The strain of yeast used is version “K” and when combined to create the specific recipe, it’s described as containing flavors of light spice, light caramel and full bodied. Like the other bottles in the single barrel collection, the bourbon in the review was aged between 7-9 years. Of note, Four Roses releases single barrel, barrel proof versions of all 10 of their recipes, however, these are only available via private selection.
