He stepped down from RTÉ in 1968 and became managing director of the United Distillers of Ireland Ltd. (later
Irish Distillers). Throughout his ten years with the group he spearheaded the integration of a company that had been created from an amalgamation of three competing distilleries and oversaw the modernisation and rationalisation of the firm by moving all whiskey production to a single site in Midleton, Co. Cork. He was also instrumental in the purchase of Bushmills Distillery and responsible for creating a partnership with the Canadian firm Seagrams, who purchased 20% of United Distillers. In 1972 he agreed to write a series of articles for the
Sunday Independent, which embroiled him in a controversy between the newspaper and the National Union of Journalists. The NUJ objected to his writing the articles on the basis that it was a threat to the employment of their members. The dispute caused the non-publication of one issue of the Sunday Independent, after which he ended the dispute by withdrawing the articles. During an all-out strike at Irish Distillers Group in 1974, McCourt focused on trade unions saying;
"Our country is involved in a war, a war that threatens the development we all legitimately seek . . . We can go a long way towards winning our share in Ireland of this particular war by putting in more than we try to take out, by some reduction in self-interest in favour of the national well-being." By the time he retired from United Distillers the company's profits had risen from £500,000 to £3,500,000. After his retirement he remained on the board until 1983. He was also director (1965–9) and chairman (1969–73) of Gorta, the famine relief agency, and chairman of
Irish Steel (1975–86); Alexander Stenhouse (Ireland) Ltd (1980–87); Algemene Bank Nederland (Ireland) Ltd (1980–85); Irish Agricultural Machinery (1982–8); and Hibernian Life Assurance Ltd (1987–9). He held a number of other directorships in Foir Teoranta (1972–9), Jefferson Smurfit Group (1979–89) and Peterson Tennant Group Ltd (1979–82). Even in later life he remained involved in business becoming director of
Fran Rooney's Baltimore Technologies. He was a benefactor of
University College Dublin's
Michael Smurfit Graduate Business School with the
McCourt University Challenge named after him from 2004. He died 13 May 2000 in Dublin. ==Personal life==
