Chardonnay Grape

Chardonnay is the most widely planted white wine grape in the world, and its real parentage was solved by the same UC Davis research team, led by Carole Meredith, that identified Cabernet Sauvignon's origin — also documented in this database. Genetic analysis found that Chardonnay is a natural cross between the well-known red Pinot Noir grape and a genuinely obscure, historically unglamorous white grape called Gouais Blanc. Gouais Blanc has a real, specific, ancient origin story of its own: it was reportedly brought west to Gaul from the Central European region of Pannonia by the Roman emperor Probus, specifically to promote wine cultivation there, even though the grape itself was never considered high quality on its own. Genuinely, both Pinot Noir and Gouais Blanc were widely grown together in medieval France, making the chance cross that produced Chardonnay plausible, and that same real parent pairing is also responsible for the red Gamay grape. Chardonnay itself originated specifically in France's Burgundy region, and has since spread to essentially every wine-growing country in the world — for many newer wine regions, successfully growing Chardonnay is treated as a real rite of passage into serious international winemaking.
