WhistlePig Declaration Wheat Whiskey is a bold yet refreshing expression of American ingenuity, crafted to commemorate 250 years of this country doing things its own way. Built on a high wheat mash bill of 100% American grain, it leans fully into wheat's naturally softer, more approachable character. A second finish in wave stave barrels adds a toasted flavor gradient and complexity. Double American oak aged and bottled at 86 proof, its exactly what summer calls for.
