CHEMICAL COMPOSITION OF AMERICAN GRAPES, 
17 
A high or low acid-sugar ratio itself carries no index of richness 
orfood quality. Itis simply astatement of the balance between these 
elements compared with each other and indicates agreeableness or 
lack of agreeableness to the palate. 
A rich juice may be quite acid in 
its fresh state, as for instance, Norton for northern Ohio, 1911, which 
is indeed a rich juice but with an acid-sugar ratio of 1 to 17.8, entirely 
too narrow for a potable juice in the fresh state. 
The indications 
are that the amelioration of such a juice by proper factory technic 1 is 
possible. 
TaBLE 3.—Comparison of total sugar and acid results for ali named varicties analyzed 
during 1908-1911 and 1913, with acid-sugar ratios. 
[Results stated in grams per 100 cc of expressed juice.]
