US Distillers Brown-Forman have acquired Slane Castle Irish Whiskey in a deal that will see the blend produced on the Co Meath estate.

The partnership between the maker of Jack Daniels and the Conyngham family will see $50m invested, creating 25 jobs in addition to those involved in construction of the distillery.

"The family will remain at the core of the business into the foreseeable future.  This is a very long-term partnership and I am incredibly excited,” said Henry Mountcharles.

"Brown Forman was absolutely the people we wanted to partner with because of their vast experience in the whiskey business,” he said. 

“It is a publically quoted company and a member of the Brown family is still chairman of the board."

He revealed that the Brown family has visited Slane, while some of the family were guests at the Foo Fighters concert held there on Saturday.

Mr Mountcharles said "this is a major boost for tourism in the whole Boyne Valley region and there will be 25 permanent jobs created. That is in addition to the construction jobs and this will have a significant positive knock on effect for guest houses, hotels and tourism in general."

He said he is "thrilled" at the development and "my son Alex and I have been working on this since 2009.  It has been something of a long and winding road but with a fabulous conclusion to it."

 "We are very excited about this new venture into Irish Whiskey," said Brown-Forman CEO Paul Varga. 

"Brown-Forman has a long history of bringing great whiskey to the world, such as Woodford Reserve, which we introduced in 1996 and has since grown to become one of the world's leading super premium bourbon brands."

Brown-Forman also make Southern Comfort and a number of tequila, vodka and wine brands.

"Irish whiskey has been one of the fastest growing segments in the global whiskey category over the last few years," stated Lawson Whiting, executive vice president and chief brands & strategy officer for Brown-Forman.

“We're excited to be partnering with the Conyngham family as we build the new Slane Irish Whiskey Distillery and introduce new Irish whiskeys to the world."

Annual sales of Irish whiskey in the United States have increased five-fold to 2.7 million cases over the past decade, according to the Distilled Spirits Council of the United States, making it the fastest-growing spirit category over that period. 

There are 12 bottles in a case.

Brown-Forman is the latest US company to invest in Irish whiskey after Beam Suntory, which makes Jim Beam and Maker's Mark, bought the Cooley Distillery for $95m in 2012.

The Slane distillery will be located in the old stable yards on the estate and there will be a Slane Castle Whiskey on the market in 2017.

Mr Mountcharles has also reassured the rock fans around the globe that this new venture will not prevent concerts at the venue.

"The concerts will go on," he declared.

Construction on the distillery will begin in the next two months.
