The source presents the 1989 Opus One as a collectible California wine. Its bottle-specific assessment gives particular weight to documents and packaging; storage conditions; and bottle format.
1989 Opus One valuation considerations
The source presents 1989 Opus One as a leading California wine from a comparatively consistent vintage. Its valuation depends mainly on bottle condition, provenance and current market demand.
Please note: bottle condition and provenance often affect the value more than the vintage alone; storage conditions, the number of moves, and the availability of invoices or the original case are all important.
Main factors affecting the valuation of Opus One
- Documents and packaging: The availability of invoices, the original case and storage records can affect buyer confidence and the valuation.
- Storage conditions: Wine kept in a temperature-controlled cellar with few moves generally has a clearer condition history.
- Bottle format: Magnums and larger formats, together with complete cases, may attract additional market interest.
- Bottle condition: Check the fill level, whether the cork has sunk, and whether the capsule or label is damaged or mouldy.
For a complete case or multiple bottles, provide a full list and photographs. Different vintages and bottle conditions can be assessed separately. Once the details are agreed, handover can take place at our shop or by collection across Hong Kong and Macau. WhatsApp / WeChat: 96737259.
