AMOUNT OF ALCOHOL IN WINE. 



167 



The following wines have been examined in the 

 same manner at a temperature of from 9 to 10 C. 

 (48-2 to 50 F.) by Vlaanderen. 



We may deduce from the above determinations, so far 

 as they concern the relation between the specific gravity 

 and alcoholic contents of wine, that the former cannot 

 be taken as the standard of the latter. The reason 

 of this is to be found in the great variety of sub- 

 stances held in solution in the wine. But even in the 

 same kind of wine the specific gravity does not furnish 

 the means for determining the alcoholic contents. 



In comparing, for example, the different kinds of 

 Port wine, we perceive a difference of from 0'9932 to 

 0-9999, whilst the former contains 20, the latter 19 per 

 cent, alcohol. Ajid the specific gravity of all kinds
