Old No.7 (1 L)

The technique at the core of Old No. 7 was originally taught to Jack Daniel by Nathan 'Nearest' Green, an enslaved man who served as the distillery's first Master Distiller — a contribution erased from official histories for over a century and only formally recognized in the 2010s.

That technique, the Lincoln County Process, remains the defining act: before any barrel contact, new-make spirit distilled to 140 proof via a 100-foot copper column still is gravity-fed drop-by-drop through 10-foot vats of handmade sugar maple charcoal over 3–5 days, stripping harsh congeners and depositing a velvety texture no standard bourbon undergoes.

The distillery sits in Cave Spring Hollow, Lynchburg, anchored by a limestone cave spring at a constant 56°F (13°C) — limestone filtration removes iron (detrimental to whiskey flavor) while contributing calcium and magnesium. Multi-storey rickhouses expose barrels to Tennessee's full seasonal temperature swings, driving aggressive wood interaction on upper floors, slower extraction below.

Old No. 7 is blended from 175–200 barrels per batch, deliberately mingling upper- and lower-floor casks to balance intensity with restraint. The 80% corn / 12% malted barley / 8% rye mash bill ferments in open-top cypress vats using a sour mash backset before reduction to 125 proof for barrel entry into 100% new charred American white oak.

The special feature: this whiskey meets every federal legal definition of straight bourbon yet deliberately refuses the label — the charcoal mellowing step is the single act that makes it something else entirely.
