When should harvest preparation begin?

Active harvest preparation should begin 4-6 weeks before the estimated first pick date. This includes verifying all PHI compliance, scheduling fruit sampling and lab analysis, confirming equipment readiness, booking labor and transportation, and coordinating with the winery or buyer. Planning should start even earlier during the growing season.

What PHI checks should be done before harvest?

Before harvest, verify that all PHI (Pre-Harvest Interval) requirements have been met for every product applied to each block. Review spray logs for the most recent applications and calculate the earliest legal harvest date for each block. Flag any blocks where PHI has not yet cleared. This is a legal requirement.

What equipment should be inspected before harvest?

Key equipment to inspect includes: harvesting equipment (mechanical harvester or picking bins/lugs), transportation vehicles, weighing scales, refractometers and sampling equipment, bin cleaning supplies, lighting for early morning picks, communication radios, and first aid kits. All equipment should be cleaned, calibrated, and tested before the first pick day.

How do I determine when to harvest grapes?

Harvest timing depends on sugar content (Brix), acidity (TA and pH), flavor development, and seed maturity. Regular sampling starting 4-6 weeks before estimated harvest helps track ripening progression. Target parameters vary by variety and wine style. Work closely with your winemaker or buyer to establish pick criteria.
