Provenance: what to check before buying at auction
The catalog tells you a great deal, but not everything. How to read a lot, what to ask before you bid and what the auction house stands behind.
What provenance means
Provenance is the record of a wine’s previous owners and, ideally, of how it was stored. It matters for two reasons. Storage shows in the bottle: a wine kept warm or dry can lose level, push its cork or simply taste tired. And provenance is what allows a buyer to trust that a bottle is what its label says.
Catalogs use a few recurring phrases. “Ex-château” or “ex-domaine” means wine released directly from the producer’s cellar, the strongest provenance there is. A “single-owner collection” is one consignor’s cellar sold as a group, usually with a description of how it was kept. “Professionally stored” means a temperature-controlled facility rather than a home cellar. None of these terms is standardized, so ask what lies behind them.
Reading the lot
Condition notes follow conventions that are similar across auction houses but not identical.
- Fill levels. In Bordeaux-shaped bottles, “into neck,” “bottom neck” and “very top shoulder” are acceptable at any age; top shoulder is usual for wines over 15 years; high shoulder is usually no problem; mid shoulder usually means some deterioration of the cork; low shoulder is a real risk. In Burgundy-shaped bottles, the level is given in centimeters below the cork, and more space is accepted in older wine.
- Labels and capsules. Bin-soiled, scuffed, nicked, torn and wine-stained labels, and nicked or corroded capsules, are usually cosmetic on their own. A stained label combined with a low fill is another matter.
- Corks and seepage. A protruding cork or signs of seepage, especially with a low level, often point to past heat. A sound cork should not move when pressed.
- Cases. An unopened original wooden case is reassuring, but some houses do not inspect every bottle inside one, and some will not accept returns for faults found after the bands are cut.
Online sales follow the same principles, with photographs doing more of the work. Where a lot matters to you, ask for more images.
Two cautions. First, the absence of a note does not always mean the absence of a problem. Some houses do not note levels above a certain point, some do not describe back labels and some illustrate a representative bottle rather than the lot itself. Second, context matters. Uneven fills within one case deserve a question, while some producers fill their bottles high, so a note of seepage can be routine for them.
Questions to ask the specialist
Specialists can often say more on the telephone than a catalog can print. Worth asking:
- Who consigned the wine, and what purchase history exists?
- Was it bought on release, and from whom?
- Where was it stored, and for how long? A professional facility or a home cellar?
- Did the house see the cellar, or open sample bottles from it?
- Has the case been opened and each bottle examined? Are there photographs of every bottle?
- For a rare bottle, has anyone compared it with known authentic examples?
Many houses also welcome inspection by appointment before the sale.
Counterfeits, and what a buyer can check
The best-known case is Rudy Kurniawan, convicted in Manhattan federal court in December 2013 and sentenced in August 2014 to ten years in prison. From 2004 to 2012 he blended less distinguished wines at his home in California, filled authentic empty bottles, recorked them and applied counterfeit labels. Among the wines he consigned were bottles of Domaine Ponsot’s Clos Saint-Denis from vintages between 1945 and 1971; Ponsot first made that wine in 1982, and the lots were withdrawn from a 2008 sale at the domaine’s request. Experts believe many of his bottles are still in circulation.
Leading houses now inspect consignments closely, and many producers have added protections of their own. Château Margaux began laser-engraving bottles in 1989 and has marked every bottle since the 1995 vintage; it added a Prooftag bubble seal in 2011 and a QR-coded seal in 2026. Château Lafite Rothschild has used bubble seals, which can be verified online, since the 2009 vintage.
A buyer can verify seal codes on producers’ websites and ask whether a wine could exist at all in a given vintage or bottling. Labels, capsules and serial numbers can be compared with known authentic bottles. But the limits are real. Counterfeiters distress labels and corks to make them look old, a working seal does not prove a bottle authentic and no system is infallible. For rare bottles, documented provenance remains the best protection.
What the auction house stands behind
Read the conditions of sale before bidding. Terms vary, but some patterns are common:
- Much wine is sold “as is,” with descriptions offered as opinion rather than warranty.
- Where a house offers an authenticity guarantee, it usually runs for a limited period after the sale or delivery, and only for the original buyer.
- Where a house accepts claims for breakage, shortages or condition, they usually have to be made within days of delivery. Many houses accept none.
- Some guarantees require the house’s sale stickers to remain on the bottles.
Keep the invoice, the catalog entry and the condition report. When the time comes to sell, they are your provenance.
Building provenance for the future
The wine you buy today is the provenance someone else will ask about later. Keep the invoice and the catalog entry with the wine’s record, move it straight into professional storage, keep original cases sealed where you can and keep the storage statements. A clear history from purchase to sale is one of the few things an owner can add to a bottle’s value.
Getting the wine home
Before you bid, confirm that the wine can be delivered where you want it. In the United States, rules on shipping wine to consumers vary by state. Some houses ship only where it is permitted, others leave delivery and its legality to the buyer and many will hold the wine in storage until it can be delivered lawfully. Many houses also hold shipments in extreme heat or cold and offer temperature-controlled transport. In Canada, wine brought into a province generally has to go through the provincial liquor authority, and the personal exemption for wine carried across the border is small. Cross-border rules have been changing, so check them before you buy.
The safest course is often to move the wine directly into professional storage and to collect it when the season and the paperwork allow.
Common mistakes
- Treating catalog descriptions and photographs as guarantees.
- Assuming that no note means a perfect bottle.
- Missing a claim window, or assuming a guarantee passes to the next owner.
- Bidding before checking that delivery is possible.
- Shipping in summer heat.
- Trusting a story rather than records.
