[3] The Kirwan family were one of the Tribes of Galway and was one of several Irish business owners who moved to Bordeaux during this period.
Their influence was not inconsiderable, with wine historian and academic Charles Ludington suggesting that Irish merchants were responsible for popularising Bordeaux drinking of the style and taste that is seen today.
The more important of these took place in 1926, when the Godard family sold Château Kirwan to Schröder & Schÿler (a longstanding Négociant and winetrading house, whose roots in Bordeaux were also centuries-old).
[5] Under the stewardship of Jean-Henri Schÿler, significant investment was made into the quality of the vines, resulting in a replanting initiative which spanned the 1960s and the 1970s.
The Schÿler family has retained ownership of Chateau Kirwan to the present day, with Philippe Delfaut serving as the managing director since 2007.
