Whiskey lovers should make a beeline for the Jameson Distillery on Bow Street, in the heart of Smithfield where Jameson was first distilled back in 1780. The guided tour is short and lively, walking you through malting, mashing and maturation before the real treat: a comparative tasting that pits Jameson against a Scotch and an American bourbon. Book the whiskey-blending add-on if you fancy going deeper. A grand rainy-afternoon option.
