This 21 year blended Scotch whisky is produced by the owners of the Springbank Distillery, J & A Mitchell & Sons. It’s comprised of a 60:40 blend of grain and malt whiskies. The grain is sourced from Girvan, a major grain distillery owned by William Grant in the Scottish Lowlands just on the other side of the Isle of Arran from Campbeltown. J & A Mitchell gives no details about the malt component, other than to say that it is the product of a single distillery.
