whisky & honey

[ozzman]

scottish concoction of whisky & honey left to ferment before being consumed?

Drambuie, the Scottish liqueur, sounds the most likely answer, but it could conceivably be Atholl (or Athole) brose, which also contains oatmeal etc. The latter is usually just served as a dessert immediately it's prepared rather than being left to ferment, though it might improve with age!

Don't forget Glayva.
