 The origin of the vineyard's name is unknown, although it is known to have been used since the High Medieval period, and at least three different hypotheses exist.The most commonly prevailing assumption is that it may come from the "bonnes mères" ("good mothers"), nuns of the Cistercian order at Notre-Dame de Tart.A second hypothesis holds that it originates in the verb "marer", to cultivate, which would give a translation of "good vintage".
