Scotland, Ingredients, Strength and Maturation Rules
Scotch Whisky must be mashed, fermented, distilled and matured in Scotland from cereals, water and yeast. It must be distilled below 94.8% ABV so the spirit retains character from its raw materials and method. Flavouring and sweetening are not permitted; plain caramel colouring may be used within the specification.
The spirit must mature in Scotland for at least three years in oak casks no larger than 700 litres and be bottled at no less than 40% ABV. These are minimum legal conditions, not promises of quality. A three-year whisky can be excellent; an older whisky is not automatically better.
