Definition: Maturity index

The ripeness index is the ratio of total sugars divided by titratable acidity.

Although there is no parallelism between variations in sugars, acids and bases, it is advisable for winegrowers to set the harvest date taking into account the total sugars and titratable acidity for each plot and each exposure. Of course, the nature of the wines to be produced (white, rosé, red, dry and sweet wines) must also be taken into account.
