berry may also be related with the ability of the pathogen to
enhance glucose transport (Azevedo et al. 2006).
Sugar content is an indicator often used to assess ripeness
and to mark the harvest. Furthermore, as most of the
sugar is fermented to ethanol during the vinification process,
the measurement of sugar content, the so-called “must
weight”, allows the control of alcohol content in the wine.
While indicating maturity level, “sugar ripeness” is not, by
itself, the best index of optimal maturity.
