We’ve been seeing a lot of whisky aged in wine barrels and beers aged in bourbon barrels, along with the occasional oddball sauvignon blanc aged in tequila casks.

Now Glenfiddich has an enticing new expression of Scotch finished in sweet rum barrels. The fourth release in the whisky’s Experimental Series, Fire & Cane is a smoky dram blending peated and non-peated whisky matured in bourbon casks. Then this combined spirit goes into rum casks from various South American nations, taking a three-month rest for increased complexity in the form of sweet caramel toffee notes with a lingering finish rich with oak.

The interplay of pronounced smoke and sweet promises to be a unique one. The marriage of Scottish whisky with North American and South American casks surely marking some kind of positive development for Western relations as well as a genre-pushing spirit.

Fire & Cane is now available for $49.99 at national liquor stores.
