The Cumbrae Supply Company is a small family business based in Renfrew, Scotland. We are known for bottling and selling ‘The Smallest Bottle of Whisky in the World’ as listed in the Guinness Book of Records.


With the trading name of The House of MacDuff, we specialise in bottling a range of single cask Scotch Whiskies under The Golden Cask brand; blended malts by batch under The Selkie brand, along with Burns Nectar single malt and Blend No 888 blended Scotch Whisky.

Grain whiskies, aged Gin and Rum will form part of our portfolio as they are developed.

Known for his expert knowledge and experience, we use the services of John McDougall as a consultant.


The Cumbrae Supply Company dates back to the 1950s when the ‘world’s smallest bottle’ was a private enterprise run out of a garage in Millport. Thereafter it was owned by the Paisley Whisky Co Ltd until 1987 when we the MacDuff family purchased it.

At this time we owned a small pottery and along with the smallest bottle our main products were whisky filled novelty items.  In the 1990’s we started to focus on bottling whisky miniatures and single casks for third parties.

With a move of premises and a small bonded facility we began to acquire stock and bottle our own brands.  In 2013 a further move brought us to Renfrew and concentration is now on developing The House of MacDuff brands.
