Pinot noir
As it seems highly likely that Pinot Noir Précoce is simply a natural early ripening mutation of Pinot noir, it is extremely likely to have occurred and been selected and specially cultivated in many different Pinot growing regions (e.g., Burgundy, Champagne, Alsace, Loire, and throughout many older German vineyards) on many separate occasions throughout the long history of Pinot noir cultivation in Europe.
