| G0Commission and wine briefYou | Accept the brief as physically and legally constructible, or revise incompatible requirements. | Category and colour · Sensory direction · Volume and release horizon · Intervention limits · Optional external standards |
|---|
| G1Inventory and grape selectionConstructor | Produce ranked single-parcel and multi-parcel candidates from registered parcels. | Parcel identity · Available volume · Farming record · Expected harvest state · Certification scope |
|---|
| G2Vineyard planFarmer | Set soil-water, rhizosphere and fruit-microclimate actions from the measured parcel state and intended wine. | Phenological stage · Downy and powdery mildew risk, reported separately · Soil and vine water state · Compaction and infiltration · Rhizosphere diagnosis · Canopy and bunch microclimate · Sampling plan |
|---|
| G3Harvest window and final grape selectionFarmer and winemaker | Define harvest segments by parcel zone, exposure, maturity, sanitary state, skin microbiology and intended route. | Sugar · pH · Titratable acidity · Berry and sanitary state · Skin microbial state · Phenolic or aromatic maturity · Berry and bunch-zone temperature · Weather forecast |
|---|
| G4Reception and lot acceptanceWinemaker | Accept, sort, split press fractions, reduce the proportion, redirect or stop. | Lot identity and mass · Transport time and temperature · Sanitary state · Sugar, pH and titratable acidity |
|---|
| G5Route commitmentWinemaker | Commit the component to its microbial, extraction and endpoint route. | Composition · YAN · Microbial strategy · Vessel and temperature capacity · Oxygen plan · Addition limits |
|---|
| G6Active fermentation and transformationWinemaker | Continue, change temperature, adjust oxygen handling, separate a fraction, revise the plan, redirect or stop. | Density trajectory · Temperature · Volatile acidity · Sensory state · Route-specific redox, oxygen or microbiology |
|---|
| G7Endpoint, assemblage and bottlingWinemaker | Finish still, bottle an active primary fermentation, assemble base wines, perform tirage, retain separately, redirect or hold. | Residual sugar or density · Alcohol · pH and titratable acidity · Volatile acidity · Microbial state · Pressure calculation where relevant |
|---|
| G8Maturation and releaseTechnical reviewer | Continue maturation, disgorge, filter, blend, correct under an allowed protocol, redirect, hold or release. | Final composition · Stability · Oxygen state · Sensory integration · Fault screen · External certificates and label text |
