 Today, however, it is difficult to get an accurate count of Mondeuse noire plantings due to the longstanding confusion and mis-identification of plantings as being Refosco (and later confusion with Calzin).While the University of California, Davis officially corrected the error in 2005, the state of California was still counting Mondeuse noire and Refosco plantings as one and the same in their 2008 acreage reports.Some producers, such as Lagier-Meredith in Napa Valley, which is owned by UC-Davis geneticist Carole Meredith, have been able to independently confirm that their plantings of Mondeuse noire as authentic.
