Thomas Street Distillery

The Thomas Street Distillery was an Irish whiskey distillery located in Dublin, Ireland. At its peak, it was Dublin's largest and most productive distillery and with an output of over 2 million gallons per annum, twice that of John Jameson's acclaimed nearby Bow Street distillery.

Alfred Barnard, a British author who visited most of the distilleries in the then United Kingdom of Great Britain and Ireland in the late 1880s, wrote that, at the time of his visit, the Thomas Street Distillery may have been the largest whiskey distillery in the world and probably had the highest output of any whiskey distillery in the British Isles. However, the distillery later entered into financial difficulties, and closed in 1926. Although most of the distillery buildings were demolished following its closure, a few were incorporated into the Guinness St. James's Gate Brewery and are still extant.

In January 2017, Diageo, producers of Guinness, announced that they would invest €25 million in establishing a new distillery in the old brewery power house building on Thomas Street, close to the site of the original Thomas Street Distillery. Production at the new distillery started in the first half of 2019. In addition, Diageo resurrected the original brand and launched a non-chill filtered, 45% ABV premium blended whiskey under the name "Roe & Co" in March 2017.
