Wine production traceability: from vineyard block to bottle, and back

Traceability tends to come up when someone talks about the QR code on the back label, but a wine’s traceability happens long before that, in the cellar. It means being able to answer two questions for any bottle or lot. Backwards: which blocks and varieties did this wine come from, which vessels was it in, what went into it? Forwards: if there is a problem with a lot of wine, of grapes or of an additive, which bottles — and which customers — did it end up with? The first question comes up in an audit or a complaint; the second, in a recall. Both only have an answer if every move of the wine was written down, and linked to the one before it.

What the rules ask — the minimum

In the European Union

• One step back, one step forward. Article 18 of Regulation (EC) No 178/2002 requires every food business operator — wineries included — to identify who supplied them (grapes, must, wine, additives, food-contact materials) and to whom they sold, and to make that information available to the authorities on request.
• Wine-sector registers. Delegated Regulation (EU) 2018/273 and Implementing Regulation (EU) 2018/274 set out the registers a winery keeps: entries and exits, stocks and oenological practices (such as enrichment, acidification or deacidification), with the volumes. National authorities check them against the harvest, production and stock declarations.
• The lot on the bottle. Directive 2011/91/EU requires every prepacked foodstuff to identify the lot it belongs to — for wine, the bottling lot printed on the bottle or the label.

In the United States

• Bonded wineries keep TTB records of production, blending, treatment, bottling, losses and removals (27 CFR part 24), and report them on the Report of Wine Premises Operations.
• Most wine is not on the FDA Food Traceability List, so the FSMA 204 traceability rule rarely applies to a winery directly — but buyers and distributors increasingly ask for the same lot-level answers.

None of these rules requires a winery to know, from a bottle, the block the grapes came from. They ask for each link to be written down; joining the links end to end is what separates traceability that exists on paper from traceability that answers questions.

The questions good traceability answers

• This bottling lot: which wine went into it, from which vessel — and that wine, from which lots and which grape receptions?
• What is this wine’s composition by variety and by block — and does it match what the label says?
• Which additives did it receive, at what rate, from which supplier lot?
• A lot of bentonite, yeast or corks is under suspicion: which wines received it, and which bottles came out of those wines?
• A block was sprayed inside its pre-harvest interval: which receptions came from it, and where did they go?

What to record, stage by stage

1. Vineyard and origin

Every block with its identification, variety, area and farming status, and the sprays and field operations done on it. This is where the chain starts: without an identified block, fruit enters the winery with no origin.

2. Harvest and reception

Every load with its block of origin, variety, weight (the weigh tag), sugar reading and destination — the tank, the press or the lot it went into. For bought fruit, the grower and their block. A reception with no recorded destination is the first place the chain breaks.

3. Fermentation

The lot in its vessel, the density and temperature readings, the additions (yeast, nutrients, SO₂) with the product, rate and supplier lot, and the end of fermentation. For whites and rosés, pressing turns kilos or tons into a lot in litres or gallons — that step has to stay linked to the receptions behind it.

4. Rackings and blends

Every racking with its source vessel, destination, volume and losses. Every blend with the lots that went in, the volume of each and the lot it produced. This is where composition is lost most often: a blend written down only as "new lot, 4,000 L" no longer knows where it came from.

5. Ageing

Every stay in tank or barrel with its dates in and out and its volume, the toppings, the cleaning of the vessel before filling, and the follow-up analyses. When a lot is aged across many barrels, it has to remain one lot — or the split has to be written down.

6. Analysis and bottling

The pre-bottling analysis, the wine lot that went to the line, the bottling lot that came out of it, the number of bottles, and the packaging used (bottles, closures, capsules, labels) with the suppliers’ lots. From there, the shipments: who received each bottling lot.

Where the chain usually breaks

• The reception that does not say which tank it went to — or that was split between two without recording how much went where.
• The blend recorded as a new lot, without its source lots and volumes.
• The racking done but not written down: volume appears in one vessel and disappears from another with no operation linking them.
• Losses nobody records, which leave the lot unable to balance in volume.
• The bottling lot printed on the bottle that is not linked, anywhere, to the wine lot it came from.
• A bulk sale of part of a lot, which takes volume out of the lot without recording who it went to.

They all have the same cause: the record is made later, somewhere else, rather than when the wine moves. One sheet per tank and another for bottling work until somebody needs to put them together.

A mock recall in half an hour

The most honest way to know whether traceability works is to test it before you need it. Pick a bottle at random from the warehouse and, with a stopwatch:

• Backwards: from the lot printed on the bottle, get to the wine lot, the vessels it went through, the additives it received, and the grape receptions and blocks of origin.
• Forwards: pick a lot of an additive used last vintage and list the wines that received it and the bottling lots that came out of them.
• Balance the volume: what went into each lot, minus the losses, has to equal what came out.

If any of the answers depends on someone remembering, or on pulling papers together from three places, that is where the chain needs work — before a complaint or an inspector finds it for you.

And the QR code on the label?

A public page with a bottle’s story — the vineyard, the harvest, the ageing — is a good way to show part of this information to the people who buy the wine. But it is a window onto traceability, not traceability itself: what stands behind it is the linked production record, and that serves the winery, the auditor and the recall first.
