Certain whiskeys not to be imported; exception.
1. After January 1, 1948, no importer or consignee of liquors shall import or accept any consignment of liquors labeled or sold as whiskey, unless the same be straight whiskey or blends of straight whiskeys aged in charred oak containers for 2 or more years after distillation and before bottling, or a blended whiskey, unless the same contain not less than 20 percent of straight whiskey or whiskeys aged in charred oak containers for 2 or more years after distillation and before bottling, blended with neutral spirits.
2. Nothing in subsection 1 shall apply to imported Scotch, Irish or Canadian whiskey.
Interestingly, this potentially prohibits the importation of certain kinds of bourbon whiskey, which has no legal requirement for minimum aging.
