This elixir comes in two forms: blended and single malt. All scotch comes from Scotland, obviously. Single malt (the better type), is classified by the geographical factors contributing to the flavor of the whisky. Speyside, the most popular variety, is so named because the water comes from the river Spey. Scotch is made from barley, which is allowed to germinate (malt), and then roasted over a peat fire. The liquor is then fermented and distilled, then aged in Kentucky bourbon casks.
