The region of Mendoza, or historically Cuyo, experienced an unprecedented wine-boom in the 19th century and early 20th century which turned it into the fifth winegrowing area of the world and the first in Latin America. The establishment of the Buenos Aires-Mendoza railroad in 1885 ended the lengthy and costly trade with carts that connected these two regions of Argentina and sparked development of vineyards in Mendoza. Furthermore, massive immigration to Río de La Plata mainly from Southern Europe increased demand and bought know-how to the old-fashioned Argentine wine industry. The vineyards of Mendoza totalled 1.000 ha in 1830 but grew to 45.000 in 1910, surpassing Chile which had during the 19th century had a larger areas planted with vines and a more modern industry. By 1910 around 80% of the area of Argentine vineyards were planted with French stock, mainly "Malbec".
