512. Everything You Didn't Know About Four Roses Single Barrels

Welcome back to the Bourbon Road, roadies! Episode 512 brings a lively gathering around the tasting mat as hosts Jim Shannon and Todd are joined by three special guests — Stanton Holder of Statiki Cigars Company, Charles Mellon of St. Petersburg, Florida, and Lenny LaRussa of Americas, Georgia. Stanton is a returning guest and longtime Bourbon Road supporter, while Charles and Lenny are brand-new roadies experiencing bourbon country for the first time. Fresh off a full day touring downtown Louisville — including a highly praised stop at the Evan Williams Experience — the group settles in for a deep dive into one of Kentucky's most storied and scientifically fascinating distilleries.

The palate follows through with cinnamon toast, brown sugar, and a custardy, pecan pinwheel quality. A dessert-forward pour with a slightly spicier tingle than the proof alone might suggest, making it an ideal after-dinner sipper. *(00:18:48)*

- Four Roses Single Barrel OBSF (100 Proof): Returning to the high-rye mash bill (60% corn, 35% rye, 5% malted barley), this release pairs it with the F yeast strain, associated with herbal, minty, and full-bodied fruit-spice characteristics. Aged seven to nine years at 100 proof, the OBSF opens with a notably herbal and minty nose — a quality the panel links directly to the elevated rye content working in concert with the yeast. The palate is rear-weighted, settling into baking spice and a gen
