 Today, outside of the plantings at the INRA's conservation vineyards, the only significant plantings of Mondeuse grise are being propagated as "Persagne grise" by Michel Grisard in Savoie.Mondeuse noire is a mid-ripening grape variety that tends to thrive on stony vineyard soils that have a high limestone and clay content.The vine can be very vigorous and high yielding which requires the cordons to be pruned short during the winter to keep the vine in check.
