| Bunch Appearance |
Typical conical bunch, compact structure; uniform berry distribution; well-developed shoulders (upper lateral clusters); peduncle green and fresh, not dried. |
Bunch intact, structure may be slightly loose; shape substantially uniform; peduncle substantially fresh, slight lignification or drying at the base is allowed. |
| Berry Size |
Very large and uniform. Diameter ≥ 26 mm (some high-end markets require ≥ 28 mm). Minimal size variation between berries. |
Large and uniform. Diameter ≥ 24 mm. No obvious size variation between berries. |
| Berry Weight |
Average berry weight ≥ 12 g (High-end fruit often requires ≥ 14 g). |
Average berry weight ≥ 10 g. |
| Coloration |
Extremely uniform coloration. All berries on the bunch must be bright red to dark red (purplish-red). ** completely free** from green or yellow berries, or green tips. |
Uniform coloration. A maximum of 5% of berries may have slightly lighter coloration (but not entirely green). The main body of the bunch must be red. |
| Soluble Solid Content (SSC/Brix) |
≥ 17.0° Brix |
≥ 16.0° Brix |
| Total Acidity |
Optimal, typically in the range of 0.5% - 0.7% (expressed as tartaric acid), forming an excellent flavor balance with high sugar. |
Same as Extra Class requirement. Flavor must be normal without excessive acidity. |
| Berry Firmness |
Very firm and crisp. No visible deformation upon gentle finger pressure. Skin is tough, with excellent resistance to handling and transport. |
Firm and crisp. Strong resistance to pressure, suitable for transport and storage. |
| Tolerances (Defects) |
Very slight. Very superficial defects not affecting the general appearance, quality, or keeping ability are allowed (e.g., slight sunscald, spray marks, scratches). Total affected area must not exceed 5% of the berry surface. ** completely free** from decay, mold, splitting, insect infestation, or insect damage. |
Slight. Slight defects not affecting the general appearance or keeping ability are allowed. Total affected area must not exceed 8% of the berry surface. ** completely free** from decay, mold, severe splitting, or insect infestation. |
| Shattering |
Very low. Almost no berries detach after gentle vibration. |
Low. Only very few berries detach after gentle vibration (typically required to be < 3%). |
