 Much longer summer days with very cold nights and a short growing season have the potential to produce wines that are markedly different from any other wines in Argentina.Under Argentine wine laws, if a grape name appears on the wine label, 100% of the wine must be composed that grape variety.The backbone of the early Argentine wine industry was the high yielding, pink skin grapes Cereza, Criolla Chica and Criolla Grande which still account for nearly 30% of all vines planted in Argentina today.
