The care employed in drawing off wine, and mixing it 
with mute wine, contributes greatly to its preservation. 
Few kinds are skipped without this precaution. It is of 
importance then, for the prevention of all its alterations, 
that all these operations should be multiplied and repeat- 
ed ; and it is to this valuable practice we are indebted 
for the power of being able to send wine to all climates, 
and to subject it to all temperatures, without fear of de- 
composition. 
Among the diseases to which wines are most subject, 
oiliness and acidity are the most common and most dan- 
gerous. 
Oiliness is an alteration which wines often contract : 
they lose their natural fluidity, and become ropy, like oil. 
The less spiritous wines turn oily ; and weak wines, 
which have fermented very little, are the most disposed to 
this malady. W eak wines, made from grapes which have 
been picked, are also subject to it. 
Wine turns oily in the best corked bottles. Of this 
there are too frequent instances in Champagne, where the 
wine of a whole vintage, when put into glass vessels, is 
exposed sometimes to this alteration. 
Oily wines furnish by distillation butalittle fat coloured 
and oily spirit. 
This fault may be corrected several ways. 
1st, By exposing the bottles to the air, and, above all? 
in a well-aired ham.
