Clare Castle is a small boutique commercial farm on 150 acres. The stud keeps a herd of approximately 16 select broodmares, the produce of which are all sold at public auction. Clare Castle only sell stock that they rear themselves and do not facilitate any boarders. In addition, three to four mares are kept in Kentucky at the world famous Ashford Stud.
The farm was initially managed by Barry Mahon who has moved on to oversee Juddmonte Ireland. His replacement for four years now has been Ben Avenel, a graduate of the INS Stud Management Course with previous experience at Tally Ho Stud.
