William Grant & Sons, a Scotland-based producer of whiskey and other spirits, is set to invest around EUR35m to build a new whiskey distillery in Ireland for its Tullamore Dew blended Irish whiskey.

The move will see production of Tullamore Dew return to its home town after 58 years, as the original site was closed in 1954.

The new pot still whiskey and malt whiskey distillery is believed to meet the production demands for the Tullamore Dew.

The distillery is expected to create 100 new jobs during the construction phase and employ 15 people at the site.

The facility will be built on a 58-acre site at Clonminch and benefits from spring water, which will be used for the triple distillation process of the whiskey.

Construction of the distillery will begin later this year and will be completed by the end of 2014.

William Grant & Sons also plans to open a new Tullamore Dew visitor centre in September.

The Clonmel facility, which employs 60 people, will continue to produce the whiskey at its site.

William Grant acquired the Tullamore Irish whiskey from C&C Group in 2010 as part of a €300m deal.

Chief executive Stella David said the investment underpins the company’s long-term commitment to Tullamore Dew, the town of Tullamore and Ireland.

"The new distillery will not only cement William Grant & Sons’ presence in Ireland, but reinforces the fact that the brand is now firmly rooted back in its original home," David said.

Tullamore Dew was first distilled in 1829 in the small town of Tullamore, Ireland. The name derives from the initials of an early owner, Daniel E Williams – DEW.

The company describes the Irish whiskey as ‘subtle, smooth and with a pleasant maltiness combined with charred wood undertones and the natural flavor of golden barley’.

The whiskey’s portfolio includes Tullamore Original, Tullamore Dew Black 43, Tullamore Dew 10 Year Old single malt, Tullamore Dew 12 Year Old Special Reserve and Tullamore Dew 10 Year Old Reserve.
