Single malt whisky is the product of a single distillery, and it is distilled from nothing but malted barley, yeast and water. After distillation it must then be matured in oak casks for at least three years before bottling, though all of the whiskies on this page have been aged for a minimum of 18 years. 18 year old single malts make superb coming of age presents, or general gifts for Father's Day or Christmas.
