In Scotland, surely they're concerned with the future supply of whisky casks, not whiskey casks.
Also, AIUI, because bourbon has to be aged in new white oak barrels, you find a lot of former bourbon barrels aging distilled spirits all throughout the world, Scotland included.
Interesting, I just looked up the details on this[0]. I’m surprised they didn’t hammer that home as well. I thought maybe you were just being pedantic at first, but that’s a good call out. I did make sure to say cask instead of barrel, as a barrel is just one size option for a cask.
They did talk about the rules of scotch vs bourbon and how some of that supply chain works for reuse.
<Maximum pedantry mode engaged> Either could be correct, because whisky casks begin as whiskey casks. It's wise to be aware of all the links in your supply chain!
