The last son of Intermezzo, Liguster, became the one to carry on the Irrlehrer line. The dark bay was born near the Swiss border, and like his sire, was purchased by the Trakehner Verband. He also served as a Zweibruecken State Stud stallion. Liguster was bred to Caterina. Caterina by Kobalt (Kobalt being Intermezzo\'s successor stallion at Schick Manor) had been successfully competing as a sport horse before becoming a broodmare.
