Casiro

Casiro I (born 2002) is a charismatic bay Holsteiner stallion standing at 1.71m. A cornerstone of the Gerd Sosath stallion station, he is one of the most versatile sires in modern breeding. In 2026, he is celebrated as a "sire for all disciplines," having passed away in August 2025 after a legendary life. He leaves behind an immense legacy, with his influence continuing through his highly successful offspring in jumping, eventing, and even dressage.

• Early Success: He was the 1c-Premium Stallion at the Holsteiner licensing and finished his performance test in Adelheidsdorf with an excellent jumping score of 8.66.

• The 2.10m Wall: Under Hendrik Sosath, Casiro became famous for his enormous scope. He won his very first Puissance class by clearing a massive 2.10m wall with ease.

• Six-Bar Specialist: He was a frequent winner of six-bar competitions at major shows like Rastede and Elmlohe, often being ridden in his later years by Janne Sosath-Hahn, who described him as "pure fun" and "like a pony" at home.
