Originally a widely planted French varietal,
Bonarda now is hard to find except in the Jura and
Savoie regions.
Bonarda is the second-most widely planted grape in Argentina,
with more that 46,000 acres planted mostly in the Mendoza wine
region. Rarely will you find a bottle of 100 percent Bonarda, as it
is more of a blending wine, usually with Malbec and/or Cabernet
Sauvignon.
You can also find it planted in California where it goes by
the name of Charbono.
