Château La Tour Blanche

Château La Tour Blanche is a wine estate in Bommes, at the heart of the Sauternes appellation, and one of the oldest and best-known producers of sweet white wine in the Bordeaux region. Founded in the 18th century, it was ranked Premier Cru Classé in the official 1855 Bordeaux Wine Classification — the highest rank any Sauternes estate can hold besides Château d'Yquem itself. The property covers roughly 46 hectares of vineyards and has combined winemaking tradition with vocational education for over a century.

How do you get to Château La Tour Blanche?

Bommes sits in the Gironde department, a short drive south of Bordeaux, right in the middle of Sauternes wine country. Arriving by car is easiest — the château lies on a local road connecting Bommes with neighbouring wine villages, close to Château d'Yquem, and the drive from Bordeaux takes around 45 minutes. Travellers relying on public transport can take a train to Langon or Preignac; from either station, a short taxi ride or rental car covers the remaining few kilometres to the estate.

What will you see on site?

Château La Tour Blanche is more than a vineyard — it's a historic residence and, unusually, home to a public wine school. Its last private owner, Daniel "Osiris" Iffla, donated the estate to the French state on the condition that a free vocational school for viticulture and winemaking be established there. Since 1911, the school has continuously trained young students and adults for careers in the wine industry, making the property a rare working blend of living education and commercial wine production.

Visits typically include the vineyards, the estate buildings, and the cellars, with guides explaining the specifics of Sauternes production — from harvesting grapes affected by noble rot (Botrytis cinerea), through the selective, hand-picked harvest carried out in several successive passes, to the long ageing process in oak barrels. The château offers several tour formats, ranging from a straightforward walk followed by a tasting, to a vertical tasting of several vintages, to gourmet experiences paired with lunch or a horse-drawn carriage ride through the vines.

When should you visit?

The château welcomes visitors year-round. From Monday to Friday, tours run without a reservation between 9am–12pm and 2pm–5:30pm. From June through October, the estate opens seven days a week, 10am–6pm, with the last visit starting at 5pm — making this stretch the most convenient for travellers who prefer to show up without booking ahead. Keep in mind that the autumn harvest period (September–October) is the busiest working season in the vineyard, offering a good chance to see the production process in action.
