Born in 1983, Brentano II was 1985 Hanoverian Licensing Champion, 1986 reserve stallion performance test winner and Hanoverian Stallion of the Year in 2003. He became the most successful breeding son of Bolero, with 1880 registered, Hanoverian branded offspring, twenty-three licensed stallion sons and 514 broodmare daughters registered in Germany, of which 105 have earned State premium mare status. His daughter, State Premium Mare Bona Dea, was the champion of the 2000 Ratje-Niebuhr Elite Mare Show.

Brentano II’s most well-known offspring were Debbie McDonald’s Brentina (out of a Lungau dam) and Sven Rothenberger’s Barclay II, both of which competed at the 2004 Olympic Games in Athens. Brentano II was highly regarded as a broodmare sire and as such was the damsire of the legendary dressage mare, Poetin.

In New Zealand, Brentano II has offspring thanks to the successful use of imported, frozen semen.
