Whiskey is primarily made from a mash of fermented cereal grains, which typically include barley, corn, rye, and wheat. The exact combination of these grains varies depending on the type of whiskey and the distiller's recipe. For example, bourbon must contain at least 51% corn, while rye whiskey requires at least 51% rye. Scotch whisky is traditionally made from malted barley
. The key ingredients in whiskey production are:
- Grains: Barley, corn, rye, and wheat are the main grains used. The choice and proportion of grains affect the flavor and classification of the whiskey.
- Water: Used throughout the process, from mashing the grains to dilution after distillation.
- Yeast: This microorganism ferments the sugars in the grain mash, producing alcohol and contributing to flavor development
After fermentation, the grain mash is distilled and then aged in wooden casks (often oak) for a period that varies by whiskey type, which further develops its flavor and color
. In summary, whiskey is made from a fermented mash of cereal grains (barley, corn, rye, wheat), water, and yeast, distilled and aged in wood barrels to create its distinctive taste and character
