Barrel-Aged Bottled Old Fashioned

Ready-to-drink bottled Old Fashioned cocktail — bourbon whiskey base (typically Kentucky straight bourbon) pre-mixed with sugar (or simple syrup) and aromatic/Peychaud's bitters, then aged in oak barrels for 1-6 months to marry the components. Bottled at cocktail strength (~30-35% ABV). Serve neat or over ice. Examples include Handy & Schiller Old Fashioned (Buffalo Trace base, Peychaud's bitters).
