140.4 proof. 9 years. Single barrel #4374. Willett Family Estate Bottled — the highest-proof 9-year Willett in the current collection and among the most powerful own-distilled Willett expressions across all age tiers.

At 140.4 proof, barrel #4374 is exceptionally high for a 9-year expression — approaching the proof levels of the oldest BTAC GTS vintages and exceeding most 10, 11, and 12-year Willett barrels also in the collection. This reflects an unusually aggressive barrel cycling trajectory for this specific rickhouse position. Note this barrel shares the same barrel number (#4374) as an OOS 9-year at 130.2 proof — a different barrel entirely, illustrating how barrel numbers can repeat in the Willett program.
