There’s a good reason the Merlot of Chile doesn’t
taste like other Merlot. Many are not entirely Merlot, but instead a blend
of Merlot and a far more exotic grape: Carmenère, a.k.a., The “Lost
Grape of Bordeaux.” Carmenère root stock had been transplanted
from France over a century ago before the particularly nasty root louse
threatened its very existence. Soon forgotten, the Carmenère grapes
grew freely with Merlot grapes and were assumed to be Merlot until, suddenly
in 1994, viticulturist Jean-Michel Boursiquit revealed the mistake. Oops!
