The Willett Family Estate Small Batch 4 Year Bourbon is a distinctive Kentucky straight bourbon from Willett Distillery, one of Bardstown's most storied family-owned distilleries. This Costco gift set includes two 750ML bottles, making it an ideal choice for gifting or stocking a home bar.

The bourbon is a blend of two classic Willett family mash bills, both entered into the barrel at 125 proof. The primary mash bill is corn-forward (72% corn, 13% rye, 15% barley), while the secondary mash bill features a higher rye content (52% corn, 38% rye, 10% barley). The final bottling proof varies by batch at the discretion of Master Distiller Drew Kulsveen, a fifth-generation whiskey maker. The result is a small-batch bourbon with legendary roots and approachable character, balanced between the sweetness of a high-corn mash and the spice of a high-rye profile.
