Based on DNA profiling, Saint Laurent or Sankt Laurent is a spontaneous crossing of a yet unknown variety and a Pinot. It was introduced into Germany from Alsace some 150 years ago and until 1990, the area under vine was very small. The name most likely derives from St. Laurentius, whose name day (August 10th) falls 10 to 12 days before Spätburgunder begins to ripen.
Since 1997, the grape variety has soared to great heights. The 670 hectacres planted in Germany are basically confined to the Pfalz and Rheinhessen.
