Is quoted by Mariti (1797) as typical of Pisa hills. In the Bullettino ampelografico, Fasc. XIV (Ministero d’Agricoltura, Industria e Commercio, 1881) is reported Bonamico as synonyms of Giacomino, pink Grape, Canaiolo romano rosso cupo, among the varieties cultivated in different municipalities of the province of Florence, while in the Fasc. XVI (Ministero d’Agricoltura, Industria e Commercio, 1883) of the same Bulletin, Bonamico is quoted by Di Rovasenda (1877) and also appears among the varieties described by the ampelographic Commission of Siena province. At the beginning of the twentieth century the Vannuccini (Viala and Vermorel, 1905) report an accurate description, claiming that the ‘Buonamico’ is a vine native to the province of Pisa (locally referred also as Durace, Giacomino or Uva di Palaia) or Lucca, from where it then spread in the rest of Tuscany. The Vigiani (1919) reports the presence of this variety in the provinces of Siena and Florence and Marzotto (1926) report the presence of Bonamico in different provinces of Tuscany. Even Musiani (1932) describes it accurately and stated that it is only rarely found in the vineyards of Siena hills. A detailed description was made by Breviglieri and Messerini (1960). In the area of Morellino di Scansano is also known as "black French" (Ferroni et al., 1999), while in the area of Montecucco is called "Knight". It is in the catalogue of Autochthonous genetic resources of Tuscany (Scalabrelli et al., 2005).
