Disclosed herein is a method of increasing the sugar (primarily glucose and fructose) content in grapes by applying to grape vines (primarily to the leaves) a compound which is vanillin or a carboxylic acid salt having from 3 to 5 carbon atoms. Grapes are customarily harvested when the sugar level is about 16% 'Brix', and application of the compounds of the present invention gives the grower a better means of controlling sugar level so that the fruit can be harvested in an orderly manner.

Ripening of grapes

Disclosed herein is a method of reducing the acid level in pomegranates by applying thereto vanillin or a carboxylic acid salt having from 3 to 5 carbon atoms. Pomegranates are customarily harvested when the acidity level is about 181/2 percent and application of the compounds of the present invention give the grower a better means of controlling acidity level so that the fruit can be harvested in an orderly manner.
