And where do those scotch and bourbon barrels go after they are done aging the original liquor?

In most cases now, they go to age beer.

And then occasionally they go back to age spirits again. Jameson's has a line where they take casks that originally aged Jameson's Irish Whiskey are sent to a brewery to age a beer, then it goes back to Jameson's for a new whiskey aging that is infused with the beer that was absorbed by the wood.

The Jameson's Caskmates series is pretty interesting.
