A Non-Distiller Producer or NDP is a distiller that sources distilled spirits from another licensed distiller. NDPs have been around for hundreds of years. When reading a label look for the words “distilled by” or “bottled by” or “distilled and bottled by” to get the detail of where a distilled spirit is made and bottled. A sourced whiskey is not a bad thing as long as the bottler or brand is clear about the source of their spirit.
