The two varieties, Cereza and Moscatel, classed as "Parral" (arbor) 
gave the heaviest yields. This is probably because of the method of 
growing them on arbors, which is more expensive both in cost of 
erection and in picking. The usual method is to grow the grapes on 
wires strung on posts and to prune the vines low. This is an inex- 
pensive method and facilitates cultivation, ripening, and harvesting. 
Of the varieties grown by this method, the most productive is the 
Crioila, which is the variety brought over more than a century ago 
by the early Spanish settlers and is very hardy. Practically all the 
vines are grafted on phylloxera-resistant stocks. 
The average per capita consumption of wine of the Republic is 
estimated to be about 14 gallons, varying greatly in different Prov- 
inces, the lowest being in the Territory of Los Andes, where it is less 
than 1 gallon, to about 30 gallons per capita in the three southern 
Territories of Chubut, Santa Cruz, and Tierra del Fuego.
