A rich juice may be quite acid inits fresh state, as for instance, Norton for northern Ohio, 1911, whichis indeed a rich juice but with an acid-sugar ratio of 1 to , entirelytoo narrow for a potable juice in the fresh state. The indicationsare that the amelioration of such a juice by proper factory technic ispossible.
