|---|---|---|---|
| Shelf above the vegetable compartment | +1°C…+3°C |

| Middle shelves | +3°C…+5°C |
⚠️ Acceptable | Suitable for short-term storage (1-2 days). |
| Refrigerator door | +5°C…+7°C |
❌ Not suitable | The temperature is unstable, the caviar spoils quickly. |
| Freshness zone (if any) | 0°C…+1°C |
✅ Optimal | Ideal for unopened caviar. |
