This is the story of how bourbon became a distinctive American whiskey, from early grain whiskey and Kentucky distilling to the rules, labels, and styles that define it today. We move from the practical beginnings of making whiskey, through the slow settling of bourbon as a named style, into the long push for honest bottles and clear standards. Then the focus widens from law to taste, using three simple style axes and four bottles to show how far apart good bourbons can sit. So before the name on the label means anything at all, it helps to begin at the point where whiskey itself first comes together.
