The Glenrothes is unleashing its new vintage on the US this month.

The 1991 Vintage Malt has been unveiled by the whisky company and will sit alongside the 1992 Vintage, which is expected to sell out in the US this spring.

"While you might imagine this Vintage would be similar to the 1992, there is a world of difference," said The Glenrothes' brand manager Alexis Pagis. "The typical characteristics of The Glenrothes are all here, of course, but the emphasis is on vanilla and butterscotch flavours.

"Like each of The Glenrothes Vintages that have come before it, the 1991 is unique, providing those fortunate enough to enjoy its richness with a new and exciting single malt experience of unmatched excellence."

The recommended retail price for the new malt will be US$77.99.
