Two ages share one bottle in 15 Stars Private Stock, a Kentucky straight bourbon marrying 7-year and 15-year stock at 107 proof. The blending team lets the younger whiskey bring spice while the older bourbon supplies deep oak, and the age math shows in the glass: cinnamon, rose petal, and apricot over maple, then citrus and baking spice balancing caramel and almond, closing on a long, soft toasted-oak finish. The strength is enough to carry flavor without demanding water, and the blend has picked up hardware a 95 from the International Wine & Spirits Competition among it. Reach for it when a single age statement feels like half the story neat after dinner, or over one small cube.
