Scottish independence would put Scotch on the rocks — and not in a refreshing way.

Experts say the price of whisky, Scotland’s second-biggest export behind oil, could skyrocket in the event the country secedes from the United Kingdom as a result of Thursday’s historic referendum.

A divorce could mean Scotland would be shut out of the 27-country European Union, losing access to its tax-free trade market until it can reapply for membership in 2016, when the split is formalized, Dutch bank Rabobank told The Guardian.

“As a result, Scotch could face increased competition from other spirits and might lose competitiveness in key EU markets,” the bank said.

The 200 countries that are huge importers of Scotch — including the whisky-loving United States — could dwindle to as few as 70, CNN reported.

Scottish independence may have other implications for Scots, both good and bad.

While the BBC would be available on the telly, Scots might have to pony up some extra cash annually for digital access.

And the beloved Union Jack flag could get a drastic makeover if the UK loses Scotland and ditches the blue and white St. Andrew’s cross, which symbolizes Scotland.

Besides parliamentary freedom, Scotland would gain bragging rights to 14 of the top 100 golf courses in the world, as well as 13 of the 65 total medals the UK took home in the 2012 London Olympics.

Some things, like Queen Elizabeth II’s reign, free university tuition and National Health Service coverage, would likely stay the same for Scots.

Recent polls show the issue of whether to dissolve the 307-year union with Britain is a toss-up.

Fifty-two percent oppose independence and 48 percent support it, according to a Telegraph poll of 1,150 Scots published Tuesday.

A different survey by Panelbase found that around 700,000 Scots, or 17 percent of adults, would consider fleeing the country if it votes for independence. About 200,000 — or 5 percent — would leave if it votes to remain in the United Kingdom.

Of Scotland’s 5.2 million people, 4.2 million are registered to vote in the referendum.

Actors Sean Connery and Alan Cumming are pro-independence, while author J.K. Rowling and actor Ewan McGregor are against.
