Old Man Winter Four Grain Bourbon is a limited, small-batch Kentucky straight bourbon whiskey produced by Preservation Distillery, crafted to honor the rich flavor profiles of mid-century "Dusty" bourbons. Each micro batch of one to three barrels is a marriage of pot-distilled bourbon and older casks aged six to nine years in a Bardstown warehouse, sourcing spirits from both Kentucky and Indiana distilleries.

The distinctive four-grain mash bill combines the sweetness of corn, the softness of wheat, the spice of rye, and the structure of malted barley, delivering a harmonious balance rarely found in traditional two-grain bourbons. Proofed with pure limestone water from Preservation Farm, this expression is bottled at 109.8 proof (54.9% ABV). Aged in new American oak barrels, seasonal temperature shifts deepen the extraction of flavor over the extended aging period.

On the nose, expect toasted oak, sweet vanilla, warm baking spice, and brown sugar. The palate delivers caramel, maple, soft winter wheat sweetness, rye spice, roasted nuts, and hints of dried fruit. The finish is long, warming, and rounded, lingering with oak, soft spice, cocoa, and caramelized sugar.
