Not since the late 60s-early 70s has the discriminating imbiber taken to scotch, but consumption is rising.  Distilleries like Glenlivet are expanding, while there are new distilleries opening shop:

In the past three years, liquor companies have spent about £600 million to expand whisky production facilities in Scotland, marking an increase in distilling capacity that has not been seen in decades, according to the Scotch Whisky Association.

The investments are being driven by rising Scotch whisky exports to the U.S., its biggest export market by value, as well as by increasing demand in emerging economies.

One reason for the increase is that it seems to be a sophisticated drink. These things usually go in cycles though.  It was just a few years ago that fine gin was on the rise.
