Whiskey (sometimes spelled “whisky”) is a highly popular and iconic liquor that’s distilled from a fermented grain mash. Whiskey uses grains and malted grains like wheat, corn, rye, barley and more. White oak casks are typically used for aged whiskey.
Bushmills, the first licensed whiskey producer in Ireland, began in 1608. While Bushmills is the world's oldest whiskey distillery, distilled liquors date back to hundreds of years before that.
Whiskey is produced worldwide, and the exact origin is unclear. Either way, bourbon, rye and scotch are unique expressions of a similar process with delicious results.
