Bardstown Bourbon Company Discovery Series 4 is the fourth release in Bardstown’s sourced-and-blended Discovery series — drawing entirely from 10+ year-old bourbon, with heavy emphasis on 13 and 15 year-old barrels. The mash bill across the source whiskeys is roughly three-quarters corn with moderate rye contribution (13–18%) and malted barley making the balance (no wheat) — producing a structured, spice-forward older bourbon with deep oak integration.
Bardstown’s Discovery series spotlights the producer’s blending expertise rather than their own distillation — each release selects, marries, and bottles aged stock sourced from established Kentucky distilleries, with the specific source barrels and proof point shifting between releases. Discovery 4’s 10+ year minimum age and 13–15 year emphasis place it among the more mature expressions in the series.
