Like all malt whiskies, Edradour is made from malted barley, yeast and water. In the case of Edradour, there is a perennial source of pure spring water from the moorlands which rise a little way above the distillery. The nearby Edradour Burn is also important to the distillery, and is used as it has been for generations, gushing down over rocks and into the heart of the distillery to cool the wort.
