In 1865, Jean-Marie Mommessin founded the wine making firm that bears his name in Burgundy, an area known as a cradle of viticulture just north of Lyon. In 1889, Mommessin acquired La Grange Saint-Pierre, ancient stone buildings in Mâcon that originally belonged to the Abbey of Cluny. Its key, the Key of St. Peter, became the famous house emblem and remains so still.

Today, the 5th generation of the Mommessin family produces and bottles wines with an abiding respect for each wine's unique character--ever careful to produce results that are "true to their type," and therefore perfect examples of their appellation.
