Cabernet Sauvignon has been around and has been a success for a long, long while, but its origins were only recently discovered.
A University of Davis duo discovered just 12 years ago that its parents are Cabernet Franc and Sauvignon Blanc. Chances are the cross arose in the 17th century in Bordeaux, when field blends were the norm. A field blend refers to a vineyard planted with many different varieties that are also picked and vinified together. You can see the family resemblances:
• Green bell pepper from Mom (Sauvignon Blanc)
• Lean structure from Dad (Cabernet Franc)
• Weediness when picked too early = both the folks
This also explains why Cabernet Franc was well-established in the vineyards of southwest France and mentioned in Bordelais literature long before Cabernet Sauvignon.
