Casall is in a class of his own also as a breeding stallion. Various international top level competitions saw Casall compete against his own offspring – impressive evidence for his ability to pass on his quality. Only some of his offspring highly successful at international level will be mentioned, like for example Cupfer, a top prospect at the stable of Marcus Ehning, H&M Chilli Willi with Nicola Philippaerts (BEL), Austria with Kent Farrington, Caillou with Karl Cook, Casallvano with Marco Kutscher, Cita with Daniel Coyle, Chesall Zimequest with Simon Delestre (FRA), Casello under Ludger Beerbaum, Cristallo A LM with Philippe Rozier (FRA), Wunschkind with Eric van der Vleuten (NED), Casall under Ali Wolff (USA), and Caracas under Jos Verlooy (BEL), to name just a few.
His daughters Vontessa, Akimba, Cascada I, and Graziella won the Elmshorn elite mare show in 2008, 2011, 2013, and 2017, respectively. His sons Casaltino and Cadilo became champion stallions of the 2013 and 2018 Neumünster stallion grading, respectively. Two Casall sons won reserve champion stallion, Catch it in 2009 and Cascadello I, which sold at a record-breaking 600,000 euros, in 2011, and Cardin became second reserve champion in 2017. So far, 72 sons have been stallion-graded in Germany and he has produced 76 state premium mares.
Year upon year, Casall foals stand out for their convincing charm and class. On the occasion of his 2017 retirement from competition in Hamburg, eight elite foals by Casall were knocked down at an average price of almost 22,000 euros; the highest-priced foal of the 2017 Elmshorn foal auction, which changed hands at 34,000 euros, was by Casall, as well. At last year’s Stephex auction sale, the highest-priced foal were by Casall, as well, with a Casall-Kannan filly knocked down at 96,000 euros and a Casall-Vigo d’Arsouille filly sold at 50,000 euros.
A three-year-old Casall daughter
drew particular attention in the Holsteiner elite riding horse collection and was knocked down at 150,000 euros.
