Guicciardini Strozzi (two families united by marriage) is one of the oldest producers in Tuscany. Their business boasts over 1000 years of activity, with the earliest testimony dating back to 994 AD. Through the centuries, the political and economic weight of the Strozzo and Guicciardini families has influenced the history not only of Tuscany, but also of Italy. The current members of the family are the 15th generation descendants of Mona Lisa. In 1850, the building of a cellar with underground galleries was started under the leadership of Francesco Guicciardini who was married to Luisa Strozzi. The Guicciardini Strozzi winery produces 22 varieties of wines. Amongst the best known labels is the Vernaccia di San Gimignano, which was produced for the first time by the winery in 1200 and exalted by Dante, Michelangelo and Boccaccio. Guicciardini Strozzi have embraced modern wine making philosophies whilst maintaining this extraordinary heritage.
