During one of the warehouse tastings to select new single cask releases for the USA, Sam Filmus and Chris Uhde fromImpExdiscovered the Weller Wheated Bourbon barrels in Kilchomans warehouses and the idea was born to create a special small batch from these casks. Five wheated bourbon barrels filled in spring 2012 were married and bottled at the popular US alcohol strength of 100 proof (50.0 % abv).

In order to emphasise the important role of the original US barrels, the contents of which are now returning from Scotland to the USA as a single malt, Kilchoman and ImpEx are still playing with the B.I.B. term. So the B.I.B. on the bottle then NATURALLY means Bourbon Influenced Batch
