The newly acquired business will operate as William Grant & Sons Irish Brands Ltd and a total of 63 employees plus other support from C&C will join the new company including 42 employees from Clonmel and 15 from Dublin.

"We shall invest significantly in the Irish operations and are committed to building a strong business in Ireland and to maintaining and developing current operations here in Clonmel."
