(typically with the dots de-emphasised using colour and font size), is a brand of Irish whiskey produced by William Grant & Sons.

[3] Its name is derived from the initials of the brand's creator, Daniel Edmund Williams (1848–1921),[4] a general manager and later owner of the original distillery.

[3] In 1954, the original distillery closed down, and with stocks of whiskey running low, the brand was sold to John Powers & Son, another Irish distiller in the 1960s, with production transferred to the Midleton Distillery, County Cork in the 1970s following a merger of three major Irish distillers.

The new distillery opened in 2014, bringing production of the whiskey back to the town after a break of sixty years.

The centre offers guided tours and tutored tastings ranging from 50 minutes to 5 hours in duration.

[3][8] In 1954, the distillery ceased production, having, like many of those in Ireland at the time, been hit by declining sales due to a number of factors such as Prohibition, the Anglo-Irish Trade War and high taxes introduced by the Irish Free State.

[3] In the 1960s, with whiskey stocks running low, rather than reopen the distillery, the owners opted to sell the brand to John Powers & Son, the Dublin distillers.
