ChaiTrace Cellar traceability software
Wine traceability and cellar management software
ChaiTrace tracks a winery's wine from harvest to bottling: grape intake, tank movements, blends, fermentations. It keeps the full history of each batch and maintains the cellar register based on these operations.
Designed from a wine estate's specifications, used in the cellar since July 2026 and still in beta: if you run into a problem, however small, I reply within 24 hours.
In collaboration with Château Latour-Martillac (new tab)

Harvest traceability
You enter the weighbridge tickets load by load: plot, grape variety, weight. ChaiTrace calculates the batch's total weight, its composition and its volume, and enters each intake in the columns of the French customs register.
- Your plots imported from an Excel file
- The yield of each plot, in kilos per hectare
- The harvest declaration prepared from the tickets
In the cellarTanks and barrels, blends, fermentations, cellar register.
Tank and barrel management
You draw your cellar layout to scale. Each tank shows its fill level, and one click opens its record. Barrels are tracked in groups, with their age. A QR label stuck on the tank opens its record on your phone.
- Tanks, foudres, amphorae and barrel groups
- Barrel filling by number of barrels, from the batch record
- Volumes you can adjust after gauging or topping up, with the difference recorded in the log
Blends and batch history
For every transfer, split or blend, ChaiTrace recalculates the volumes and the composition of the new batch, by plot and by grape variety, and keeps its lineage.
- Two appellations, or red with white: the blend is blocked
- Two vintages: you are asked to confirm
- Every correction or cancellation is recorded in the batch log
Fermentation monitoring
Each day you enter the density and temperature of each tank. ChaiTrace plots the curves and flags anomalies (late start, slow or stuck fermentation, temperature too high or too low, doubtful reading), saying what to do.
- Laboratory analyses imported from a CSV or Excel file
- Product additions with their dose and stock, flagging those that must appear on the label
- Reminders for analyses and routine tasks
Cellar register and declarations
The register is fed by cellar operations: grape intake, movements, removals, bottlings. ChaiTrace compares the register stock with the volume actually in tank and prepares the figures for your monthly declaration to French customs.
- The packaged wine register and the bottle stock
- Regulatory labelling and the organic certification file
- An annual report in PDF, and every list exportable to Excel
These reports help you with your declarations: the declaration itself is still made on the French customs portal.
On tablets and phones
ChaiTrace is installed on the cellar computer. The estate's tablets and phones connect to it over Wi-Fi, with nothing to install, so you can enter an analysis or an addition right at the tank.
- One account per person, with their own code and role: administrator, data entry or read-only
- An activity log of who did what, and when
- In French and 25 other languages, including English, Spanish, Portuguese and Romanian, for harvest teams
- No Internet needed day to day: one connection a week is enough for the licence
- An automatic backup every day
- A guided tour to get to grips with it, on a practice estate

Frequently asked questions
The software
What is wine traceability software?
It is software that records every operation carried out on the wine, from grape intake to bottling: transfers, blends, product additions, analyses. At any time, you can find the origin and history of each batch. ChaiTrace also uses these records to keep your cellar register.
Is ChaiTrace right for my estate?
It is made for wine estates and independent wineries, from a few tanks to several dozen, for red and white alike, and it can manage several estates on the same computer. You can try it for 30 days to see for yourself.
Does ChaiTrace do my DRM, the monthly declaration to French customs?
It prepares the figures for your monthly summary declaration (DRM) and keeps your cellar register based on your operations. The declaration itself is still made on the French customs portal: ChaiTrace helps you fill it in, but does not submit it for you.
Can I bring over my existing data?
Yes for your plots and vessels, imported from an Excel or CSV file, and for your laboratory's analyses. For the rest, I help you get started.
How many people can use it?
As many as you like, at no extra cost. Everyone has their own account and code, with a role: administrator, data entry or read-only. The subscription covers one computer, and every device on the estate that connects to it.
Which languages is ChaiTrace available in?
In French and 25 other languages, including English, Spanish, Italian, German, Portuguese and Romanian. Each person chooses their own on their device. This website is available in the same languages.
Installation
What computer does it run on?
On a computer running Windows 10 or 11, in the cellar or in the office. The estate's tablets and phones connect to it over Wi-Fi, from their browser, with nothing to install.
Windows shows a message on first launch: is that normal?
Yes. Windows shows “Windows protected your PC” for recent software that it does not know yet: click “More info”, then “Run anyway”. If it then asks you to allow “Node.js JavaScript Runtime”, the engine behind ChaiTrace, click “Allow access” so that the tablets can connect to it. All the steps are on the Install ChaiTrace page.
Do I need the Internet to use ChaiTrace?
Not all the time. Day to day, ChaiTrace works offline. The key is activated online the first time, then checked automatically when the computer is connected, which must happen at least once every 7 days.
Where is my data stored?
On your cellar computer, in a file that belongs to you. I have no access to it and receive no copy of it. ChaiTrace makes an automatic backup of it every day; also keep a copy on a USB stick or an external drive.
The trial and the subscription
How does the free trial work?
You sign up online, at the bottom of this page, with your bank card: nothing is charged during the 30-day trial. Your access key and the download link appear straight away, with every feature. At the end of the trial, the subscription starts automatically, and Link reminds you by email a few days before. If you cancel before the end, on app.link.com, you are not charged anything.
How does payment work?
After the trial, the subscription is paid in advance by bank card: €20 each month, or €200 for the year, VAT included, and this price does not go up as long as you remain a subscriber. The sale is handled by Link, Stripe's payment service: it collects the payment, handles the VAT and sends you an invoice for each billing period. Your business can reclaim the VAT shown on it, if it is registered for VAT.
Can I stop whenever I like?
Yes, at no cost: you cancel online at app.link.com, with the email address you signed up with, or you let me know by email. The subscription ends at the end of the period already paid for. Your data stays on your computer; export your registers and lists to Excel or PDF before the end. If you come back, you will find everything as you left it.
