Irish whiskey producers north and south of the border fret over US tariffs

For an Irish whiskey producer in the town of Dundalk, near the UK border with Northern Ireland, tariffs of 20 percent on EU alcoholic drinks are an unexpected "curve ball".

But for competitors across the border, the tariff rate is just 10 percent.

"Distilleries in the north of Ireland have an advantage.

And in business, when you have an advantage, you take advantage," says whiskey producer Tony Healy.
