The source describes established collector interest in the 1991 Opus One, a California wine. Its bottle-specific assessment gives particular weight to storage conditions; bottle condition; and bottle format and quantity.
1991 Opus One valuation considerations
The source presents 1991 Opus One as a representative collectible California wine. Its valuation depends on the bottle’s physical condition and current demand.
Regardless of the vintage, the physical condition of the bottle remains central to the valuation: the fill level, label and capsule integrity, original case and provenance evidence all matter.
What Dibao Wine reviews when valuing Opus One
- Storage conditions: Wine kept in a temperature-controlled cellar with few moves generally has a clearer condition history.
- Bottle condition: Check the fill level, whether the cork has sunk, and whether the capsule or label is damaged or mouldy.
- Bottle format and quantity: Large formats and complete cases often attract stronger market interest and may support a higher valuation.
- Provenance and packaging: Invoices, the original wooden case (OWC) and cellar records strengthen the provenance file; a complete case is preferable where available.
For an initial valuation, provide the vintage, quantity and bottle photographs. Dibao Wine will review the physical condition and market demand before indicating a valuation. Handover can take place at our shop or by collection through a clear process; public market information is for reference only. WhatsApp / WeChat: 96737259.
