Muckle Flugga is a blend of 4 Single Malts that was shipped to Unst, near the Muckle Flugga lighthouse on the Shetland Islands. 2 of the 4 barrels in which these whiskies matured are made of staves from larger barrels that previously contained Scotch. The other 2 were made of German oak in Germany. The whisky spends a year on the island and survives the harsh seasons before returning to the mainland to be bottled.
