Did you know that malt whisky owes its existence in the marketplace to the stock market crash of 1973-74?

Neither did I, so when one of the people I interviewed for the craft distilling episode a few weeks back made that claim, I wanted to know more. Unfortunately, if you just plug "scotch whisky economic history" into an online search engine, you don't find anything of real interest, at least not in the first few thousand hits.
