The modern Tullamore D.E.W. distillery opened in 2014 on the western edge of town, returning whiskey production to Tullamore after a sixty-year gap. Tours take visitors through the distilling, maturation, and blending process, ending with a tasting of the triple-distilled Irish whiskey the brand is known for. The visitor centre is well-designed and the staff are knowledgeable about both the technical process and the local history.
The original bonded warehouse in the town centre — where the whiskey was made from 1829 until the distillery closed in 1954 — now houses the Tullamore D.E.W. Heritage Centre. It tells the story of the brand's long history and of the town's connection to the wider Irish whiskey industry. Both sites are worth visiting if you are in Tullamore for more than a few hours.
