Title
Understanding variability in winegrape production systems

Other claims from this paper (6)
- Observation Patterns of winegrape yield variation were temporally stable across seasons.
- Method / resource K-means clustering was more statistically robust than the yield target method for zoning.
- Observation Incorporating expert knowledge into the yield target method helped managers accommodate abnormal events.
- Observation Wine characteristics varied from zone to zone within winegrape blocks.
- Observation The ranking of wine scores for vineyard zones changed between seasons.
- Recommendation Zonal vineyard management is recommended for winegrape blocks rather than uniform management.
