134? On the Cultivation of the Vine? 
can be able to discover the effect of climate alone. It is 
thus that we often find the different qualities of wine 
united under the same climate, because the soil, expo- 
sure, and cultivation, modify and mask the immediate ac- 
tion of that grand agent. 
On the other hand, there are some vine plants which 
do not leave us the choice of cultivating them indiscri- 
minately in any latitude at pleasure. Soil, climate, ex- 
posure, cultivation, all ought to be appropriated to their 
inflexible nature ; and the least violation of this natural 
character essentially alters the product. Thus, the vines 
of Greece transported to Italy no longer produced the 
same wine; and those of Falernum, cultivated at the 
bottom of Vesuvius, have changed their nature. It is 
confirmed by daily experience that the plants of Burgun- 
dy transported to the south no longer produce wines so 
agreeable and delicate. 
It is therefore proved that the characters by which cer- 
tain vines are distinguished cannot be reproduced in dif- 
ferent sites ; for this purpose the constant influence of the 
same causes is necessary, and, as it is impossible to unite 
them all, the consequence must be changes and modifi- 
cations. 
W e may therefore conclude that warm climates, by fa- 
vouring the formation of the saccharine principle, must 
produce wines highly spirituous, as sugar is necessary to 
their formation. But the fermentation must he conduct- 
ed in such a manner as to decompose all the sugar of the 
grapes, otherwise the result will be wines exceedingly 
luscious and sweet, as lias been observed in some of the 
southern countries, and in all cases where the saccharine 
juice of the grapes is too much concentrated to experi- 
ence a complete decomposition. 
The cold climates can give birth only to weak and ex- 
ceedingly aqueous wines, which have sometimes an
