Harvest Readiness Assessment for Viticulturists
Evaluate grape maturity, weather, and logistics to time harvests perfectly
What You Can Do
This skill guides you through a structured assessment framework that integrates brix analysis, pH and titratable acidity measurements, weather forecasts, and labor logistics to determine optimal harvest timing for your specific vineyard conditions. You'll synthesize micro-climate data, varietal behavior, and target wine profiles into defensible harvest decisions under real-time pressure, whether managing single blocks or multiple parcels with different ripeness trajectories.
Features
evaluate brix, pH, TA, and phenolic ripeness against your target specifications
assess rain risk, temperature spikes, and frost forecasts to identify harvest windows
track ripeness trajectories across vineyard parcels and prioritize harvest order
align labor availability, equipment scheduling, and processing capacity with fruit readiness
generate justified harvest recommendations defensible to winemakers and stakeholders
apply ripeness thresholds and timing strategies tailored to your grape varieties
evaluate harvest-now vs. wait-3-days vs. wait-1-week outcomes
Example Output
Harvest Readiness Report – Cabernet Sauvignon Block 7A
✓ Fruit Status: Brix 24.2 (target 24.0–24.5), pH 3.52 (optimal), TA 5.8 g/L (acceptable). Phenolic ripeness estimated 85–90% based on seed color and skin tannin evaluation.
✓ Weather Window: 72-hour forecast shows clear conditions through Thursday morning, then 40% rain probability Friday. Recommend harvest Wednesday–Thursday.
✓ Logistics Ready: Crush pad staffed through Friday. Refrigeration capacity available for 8 tons. Labor crew confirms 15 pickers available Wednesday morning.
✓ Recommendation: Harvest Wednesday, September 15. Fruit meets quality targets, weather window is narrow, and operational resources are aligned. Delay risks rain damage and phenolic regression.
