The Famous Grouse recently had its royal warrant renewed for another five years. A royal warrant is issued to vendors whose products have been used by a member of the royal family for at least five years. It is considered the highest honor a UK business can receive.

The venerable blended Scotch brand first received the royal warrant in 1984, allowing the royal coat of arms and the words "by appontment" to be displayed on the bottle. Currently, only 800 suppliers have been granted the honor.
