Château Lanessan is an estate in the Haut-Médoc, Bordeaux. Castello di Gabbiano is a castle in Chianti Classico. DAOU Mountain sits in the hills west of Paso Robles, California.
Three countries, three very different labels. One owner: Treasury Wine Estates, a company listed on the Australian Securities Exchange — the same company that owns Penfolds. It holds 78.6% of Lanessan and 100% of the other two, and it says so in its own annual report.
Wine labels tell you a place. They rarely tell you who owns the place. So we built a lookup that does: Who owns this wine? lists 87 wine brands next to the listed company that owns them, the stake, and the filing that says so.
Labels that cross a border
Most listed wine companies own vineyards at home. These are the ones whose sites sit in a different country from the owner, each read from the owner's own filing or official page (register checked 8 October 2026):
| Site | Where it is | Owner | Listed in |
|---|---|---|---|
| Château Lanessan | Haut-Médoc, Bordeaux, France | Treasury Wine Estates (78.6%) | Australia |
| Castello di Gabbiano | Chianti Classico, Tuscany, Italy | Treasury Wine Estates (100%) | Australia |
| DAOU Mountain | Paso Robles, California, USA | Treasury Wine Estates (100%) | Australia |
| Bonterra Organic Estates | Mendocino County, California, USA | Viña Concha y Toro | Chile |
| Bodega Trivento | Mendoza, Argentina | Viña Concha y Toro (100%) | Chile |
| Finca La Celia | Uco Valley, Mendoza, Argentina | Viña San Pedro Tarapacá | Chile |
| Masi Tupungato | Uco Valley, Mendoza, Argentina | Masi Agricola (100%) | Italy |
| Kilikanoon | Clare Valley, South Australia | Yantai Changyu Pioneer Wine (99%) | China (Shenzhen) |
| Barossa Valley Estate | Barossa, South Australia | Delegat Group (100%) | New Zealand |
| L'Avenir Wine Estate | Stellenbosch, South Africa | AdVini (100%) | France |
| Quinta do Grifo · Quinta de Monsul (Rozès) | Douro, Portugal | Maison Pommery & Associés | France |
| Maison Veuve Amiot | Saumur, Loire, France | Schloss Wachenheim | Germany |
| ZAREA · Domeniile Dealu Mare | Romania | Ambra (51.15% of ZAREA) | Poland |
A few things jump out. The flow is not one-way from the Old World to the New: an Australian company owns a Bordeaux château and a Chianti castle, a Chinese company owns a Clare Valley winery, and two Chilean companies own wineries across the Andes in Mendoza — one of them also owns a Californian organic brand.
Why "who owns it" is a data problem
None of this is secret. It is just scattered: Note 28 of one annual report, a registration document in French, a Shenzhen exchange filing in Chinese. Every row in the register carries the URL of the document it came from and the locator inside it, so you can check any line yourself.
Where a filing names a site as the company's own but gives no percentage, the stake column says "—" rather than guessing.
Use the data
Everything is free under CC BY 4.0. The site-level file is one CSV with a source on every row:
import pandas as pd
sites = pd.read_csv("https://boomcellar.com/data/listed-wine-map.csv")
# every site one listed company owns, wherever it is
twe = sites[sites.company == "Treasury Wine Estates"]
print(twe[["name", "locality", "country", "stake_pct", "source_url"]])
# how many mapped sites each country hosts
print(sites.country.value_counts())
