Not much info on the bottle. KSBW aged three years in American white oak barrels. Finished in Navigator Red Wine Barrells. Precision Wine (Navigator) lists a "Barrel Bomb" wine as coming soon on their website. They describe it as "High-quality Kentucky Bourbon aged for three years in New American oak, which is transferred to french oak wine barrels inside of which Cabernet and Red blends were initially matured. That wine is then transferred back into those very same Bourbon Barrels to enhance the wine." I suspect this is the Bourbon they used. Strong red wine influence on what tastes and smells like Basil Hayden bourbon. Decent for sipping imo. Would not purchase at normal price, but it’s well worth it with the 5 cent sale at BevMo.
