I was on a ferry to Islay, ground zero for the best whisky in the world, to kill some liver cells with a dram or two.
I chatted with a bloke onboard, he had driven on a large lorry that was loaded with bourbon barrels from the US. Each barrel was knocked apart for transportation and numbered for reassembly once they arrived at the distilleries.
The frugal Scots will use them over and over until all the tannins have leached from the wood, they then chop the barrels up to smoke their salmon, herring, etc.
A dram or twa, indeed. Its a very fine thing, American whiskey barrels to help make very fine Scots whisky, dae ye ken.
