Barone Bettino Ricasoli (1809-1880) was an influential Italian politician and winemaker, known for his role in the unification of Italy. He served as the Prime Minister of the Kingdom of Italy twice and was a prominent figure in the Risorgimento, the movement that led to Italy's unification. Ricasoli was a supporter of a constitutional monarchy and worked to promote liberal policies during his political career. In addition to his political contributions, Ricasoli was a pioneer in the wine industry, particularly in the Chianti region. He developed the famous Ricasoli formula for Chianti wine, which established the blend of grapes that is still used today. His legacy continues through his contributions to both Italian politics and viticulture.
