The Malbec grape, originally grown in France, has become the main varietal in Argentina  This is surprising because most Malbec grown in Argentina is grown at high altitudes, whereas the Malbec grape once was grown at low altitudes
Ttherefore, Argentinian winegrowers should grow the Malbec grape at low elevations
The soil at high altitudes is filled with nutrients that help many of Argentina's varietals flourish.
