Leopoldo spent 28 years working as an administrator in the Imperial government of Lombardy-Veneto. In 1840, he was paralyzed by illness and had to retire. He was 48. Not wanting to be idle, he began studying viticulture. In a memoir from the mid-1800’s, he spoke about the successful results of the French varietals planted at the Piedmont estate. In 1862, he composed his first catalogue of the 175 varietals of vines that he had growing in pots. In 1869, he composed a second catalogue. In this one he had Cabernet Sauvignon listed at #93 and Cabernet Franc at #145. According to his writings, he figured them to be the most valuable of all the varietals that he had introduced. Leopoldo died in 1871. Unfortunately, his nursery did not survive for long after his death, but his catalogue did. It became an invaluable resource for his great-grandson Mario.
Mario Incisa della Rocchetta grew up in Piedmont then Rome. He fought in the first World War as part of the cavalry and afterwards he enrolled in the faculty of Agriculture in Pisa. He brought the horse he rode during the war with him. During this time, he became involved in the local equestrian community and it was through his love of thoroughbred horses that he met Clarice della Gherardesca. She was the daughter of Giuseppe della Gherardesca and the American Harriet Taylor. Mario and Clarice married in 1930 in the old church in Bolgheri then settled in Rome and restored one of the properties owned by Mario’s mother. It was here that they began to raise thoroughbreds and the most famous Italian racehorse of all time, Ribot, came from their stable.
