Harvest timing is the decision of when to pick or cut a crop based on maturity indicators such as sugar content, colour, firmness and dry matter, and it directly determines the grade, processing suitability and shelf life of the delivered product.
In trade practice
For frozen fruit and vegetables, processors set internal harvest windows based on Brix, dry-matter or colour readings taken in the field, and crops harvested outside these windows frequently fail incoming QA checks. Suppliers should document the maturity parameters used for each harvest decision, as this record supports traceability and dispute resolution when a buyer rejects a lot for under- or over-maturity. A common issue in berry supply is harvesting under pressure from weather or logistics, which compresses the window and increases defect rates.
In a specification
A product specification may define minimum Brix, dry-matter percentage or colour grade at intake, which implicitly constrains harvest timing; some contracts for processing-grade fruit also specify a maximum interval between harvest and freezing to preserve quality.
