Determining the pick date The first step begins with the decision to pick the grapes. Although outwardly it seems so simple there are many factors that contribute to this decision.
Weather is the most important contributing factor.
If it's too hot then the grapes have to be picked at night. If it looks like a long period of rain may come, the grapes may have to be picked before optimal maturity levels. Early frosts can have a devastating effect, as well as early freezes. The grape variety, combined with wine style, will determine the pick dates. This sees the ripeness of the grape being analyzed and judged.
