Scotch is a type of whisky that is made in Scotland. It is typically distilled from malted barley and aged in wooden casks for at least three years. There are two main types of Scotch: single malt, which comes from one distillery and is made from 100% malted barley, and blended Scotch, which combines malt and grain whiskies from different distilleries. The production of Scotch is regulated by strict laws, ensuring quality and authenticity. It must be produced in specific regions of Scotland, such as Speyside or Islay, each known for distinct flavors. Scotch is enjoyed neat, on the rocks, or in cocktails.
