Jack Daniel's Single Barrel Coy Hill 2021 137.9 Proof

137.9 proof. Jack Daniel's Single Barrel Coy Hill 2021 — among the most powerful single barrel expressions ever released by the world's best-selling American whiskey brand. Uncut, unfiltered, Lincoln County Process.

Jack Daniel's Coy Hill is named for the highest point on the Lynchburg, Tennessee distillery campus — where the extreme temperature fluctuations (hottest in summer, coldest in winter) produce the most accelerated barrel cycling on the property, resulting in greater caramelization of wood sugars and higher natural proof concentration than anywhere else on the estate. Barrels selected from Coy Hill represent the outer limit of what the Jack Daniel's production process can naturally produce.

The 2021 Coy Hill release marks a historic moment: the world's most recognizable American whiskey brand bottling at 137+ proof without dilution. The Lincoln County Process — filtering new spirit through 10 feet of sugar maple charcoal before barrel entry — means this is Tennessee whiskey, not bourbon. Even at 137.9 proof, the Coy Hill retains the characteristic smoothness that the charcoal mellowing imparts.

The Wooden Cork 2021 Coy Hill collection spans a range of individual barrels each presenting a distinct expression of the Coy Hill hilltop aging environment.

Frequently Asked Questions

• What makes Coy Hill barrels different from standard Jack Daniel's? Coy Hill is the highest elevation point on the Jack Daniel's campus, experiencing the most extreme seasonal temperature swings. Greater temperature fluctuation means more aggressive barrel cycling — the whiskey expands deeper into the wood in summer heat and contracts back in winter cold, extracting more caramelized sugars and concentrating to higher natural proof than lower-elevation barrels.
• How should a 137.9 proof whiskey be served? A small amount of water or a single large ice cube opens the aromatics significantly. Neat tasting first is recommended to experience the full intensity before diluting.
