D. The original name for Cabernet Franc
Achéria is the oldest name for, and most primitive clone of, Cabernet Franc. Although widely assumed to have originated in Bordeaux, Cabernet Franc (Achéria) is native to the Basque Country of northern Spain. From there it spread over the Pyrenees to the Gironde (the area around Bordeaux), where it encountered Sauvignon Blanc (which, for its part, had moved south from the Loire Valley). In the Gironde, Cabernet Franc and Sauvignon Blanc had a nice moment in Nature and gave birth to Cabernet Sauvignon.
