The House of MacDuff specialises in bottling single cask whiskies. For their Fifty/50/Gin, they aged half of our London dry style gin in casks for 20 years. For the first 10 years, they chose virgin oak casks, this to infuse sweet vanilla, ginger and strong oak flavours and for the second 10 years, they chose ex whisky casks. These allowed the wood to slowly impart greater depth and a more gentle range of flavours.
