O.H. Ingram River Aged Flagship Straight Bourbon is distilled by Green River Distilling Co. and matured in a floating rickhouse on the Mississippi River in Columbus, Kentucky. This single-barrel release varies by proof and barrel-specific aging details.
While it's hard to quantify what river-aging adds to the whiskey, it has distinct vanilla sweetness, finishing long but fairly hot with cayenne and black pepper heat. Adding water elongates the maple sugar exhale.
