The Frescobaldi family began producing Tuscan wine in 1308 and soon developed a notable client base. In exchange for paintings, the Frescobaldis traded their wine with the Italian Renaissance painter Michelangelo. The family also supplied wine to Henry VIII; surviving contracts in the family archives are signed by the English king. The agronomist Vittorio degli Albizi was an in-law of the Frescobaldi family through the marriage of his sister Leonida to Angiolo Frescobaldi; with Frescobaldi financing he was able to pioneer modern wine production techniques in Tuscany. In 1855, Albizi introduced Chardonnay, Cabernet and Marlot vines to the region.
