Why the wooden case is worth more than the wood.
Break open an original case to count the bottles and you have just reduced the value of what is inside it. This is the least intuitive rule in the trade.
Three letters appear constantly in fine wine listings and are rarely explained: OWC, original wooden case. They mean the bottles are still in the case the estate shipped them in. On a serious wine, that case is worth a meaningful premium over the same bottles standing loose on a shelf, and collectors new to the market routinely destroy that premium in the first ten minutes.
Why a sealed case is worth more
Four reasons, in descending order of importance.
It is evidence. A sealed case has not been opened, so no bottle inside has been swapped, inspected, mishandled or replaced. The single strongest provenance statement available for a young-to-middle-aged fine wine is that it has never been out of its case.
It is protection. Wood is a better insulator than a rack and far better than a cardboard carton. Bottles in a case have moved less, seen less light, and endured smaller temperature swings.
It is a record. The end panel carries the estate name, the vintage, the format, the number of bottles, and frequently the négociant or shipper's stencil. That stencil is a line in the chain of custody, and in practice is often the only physical evidence of where a case entered the market.
It is liquidity. Trade buyers and auction houses price cased wine above loose wine, in part for the three reasons above and in part because a case is a single lot that moves without repacking.
What the abbreviations mean
| On a listing | What it means |
|---|---|
| OWC | Original wooden case |
| OWC/1, OWC/3, OWC/6 | Original case containing 1, 3 or 6 bottles |
| Sealed OWC | Unopened, straps and lid intact |
| Opened OWC | Original case, but the lid has been off |
| OC | Original carton, cardboard rather than wood |
| Loose | No original packaging |
Italy uses small-format cases far more than Bordeaux does. Masseto ships in original three-bottle cases, which is why a holding is quoted in cases rather than in bottles, and why sixty bottles of the 2020 in original cases is a materially different proposition from sixty loose bottles of it.
The rules, which are short
- Do not open a sealed case to look at the bottles. If you need to see them, ask the seller for
photographs taken before sealing, or accept that opening it costs money.
- Do not split a case of a single vintage to make an inventory tidier. Twelve bottles in a case are worth
more than twelve bottles.
- Do not discard the case when the wine is drunk over the years. An original case with the correct
stencil, even empty, matters to the remaining bottles.
- Do not repaint, sand or restore a case. A worn case is honest; a refreshed one raises exactly the wrong
question.
- Photograph the end panel when you inventory a cellar. It is the most information-dense image you can
take, and it takes four seconds.
A rule of thumb worth having: anything that makes a case look better than its age is a cost, not an
improvement.
In this cellar
Several holdings here exist only as cases and are offered that way. The Masseto 2020 is held in original three-bottle cases; the Monfortino bottles are described individually because that is how they have survived. Where a case is sealed we say sealed, where it has been opened we say opened, and where there is no case we say loose. The note on fill levels covers the other half of the same description.
What does OWC mean in a wine listing?
Original wooden case: the bottles are still in the case the estate shipped them in. Variants such as OWC/3 or OWC/6 give the number of bottles the case holds.
Is a sealed original case worth more than loose bottles?
Yes, generally a meaningful premium. A sealed case proves the bottles have not been opened, inspected or swapped, protects them better than a rack, and carries the estate and shipper markings that document where the wine has been.
Should I open an original case to check the bottles?
No. Opening it removes the strongest provenance evidence attached to the wine. Ask the seller for photographs instead.
Does an empty original case have any value?
Yes, as provenance for the remaining bottles from the same case, and to trade buyers as packaging. It should never be thrown away or restored.
