As you likely know, Four Roses produces ten different Bourbons off their stills. To accomplish this, they using two grain bills--OE, at 20% rye, and OB at 35% rye--and five yeasts--K, F, O, Q, and V. After maturation in their unique single-story warehouses, these ten recipes yield a wide range of flavor, which Four Roses usually vats together to produce their various Bourbons. Now, for the first time, you can taste these Bourbons in single barrel format, straight from the barrel, exploring the flavor of one yeast strain at a time using both grain bills. Eventually, we will offer all ten whiskeys. Check back for future releases.

This OESK features the 20% rye grain bill fermented with K yeast. K yeast delivers a notable spiciness distinct from that of rye grain. K yeast also functions as one of the more traditional tasting Bourbons in the Four Roses family.

Let me hip you to one more neat-o thing about these K yeast whiskeys. There are several Four Roses exclusive to the Japanese market. One of these is Black Label, 80 proof and composed of equal parts OESK and OBSK. I've tried it at the distillery tasting lab, and it's quite nice for 80 proof, firmer and more toothsome than the Yellow Label. Well, if you pour equal amounts of these Party Source Barrel Proof bottlings and you'll have Black Label--but better than it ever was, uncut, unfiltered, and not, I assure you, exported to Japan.
