Scotch is a type of whisky that is distilled and aged for a minimum of three years in Scotland, according to specific production regulations. It is made from malted barley, water, and yeast, and is typically matured in oak casks, which impart flavor and color to the spirit. There are several different styles of scotch, including single malt, blended malt, blended Scotch whisky, and grain whisky. Each type has its own unique characteristics and flavor profile, ranging from smooth and light to rich and peaty. Scotch is widely considered to be one of the finest spirits in the world, and is enjoyed both straight and in cocktails.
