[2] In the 1960s, Cork Distilleries Company launched a whiskey, called Hewitt's, which paid homage to the Watercourse's original owners.

In 1799, Hewitt, Teulon and Blunt were joined by James Morrogh, as an equal partner in the firm, each having invested.

[1] When Alfred Barnard, the British historian visited the distillery in the 1880s, he stated that over 6,000 barrels of casks of whiskey were maturing at the premises.

[1] The yeast produced at the distillery was marketed under the name "Terrier" by a separate company called the Cork Yeast Company (CYC), displacing imports from Holland; while the industrial alcohol, produced using a Coffey Still, was exported for use in explosives, demand for industrial alcohol in the United Kingdom having grown eight-fold during World War I.

[7] Subsequently, traditional distilling operations regained importance, with samples of grain whiskey produced at the Watercourse distillery during this period (1951), recently selling at auction for €1,450.
