Château La Tour Blanche
A state-owned Sauternes estate and Premier Cru Classé producer known for botrytized sweet white wine.
Last updated August 21, 2026
Overview
Château La Tour Blanche, also known as La Tour-Blanche, is a historic wine estate in Bommes, in France’s Gironde department. It belongs to the Sauternes appellation in the wider Graves wine region of Bordeaux and is recognized as a Premier Cru Classé, or First Growth, in the original 1855 Bordeaux Wine Official Classification. Its principal identity is built around sweet white wines made from grapes affected by noble rot, the botrytis cinerea that concentrates sugars, acidity and aromatic compounds under suitable climatic conditions. The property is unusual among Bordeaux classified-growth estates because it is owned by the French state. The estate came into state ownership through the bequest of Daniel Iffla, widely known by the nickname “Osiris,” who died in 1907. Iffla stipulated that the property should serve an agricultural-education purpose. From 1911, the estate has been associated with the La Tour Blanche School of Viticulture and Oenology, which provides education and professional training for the wine sector while also operating the classified winery. This combination of production and instruction gives La Tour Blanche a role that extends beyond commercial wine branding: it is also an institutional site for teaching viticulture, cellar practice and oenology. The estate’s recorded history reaches back to the eighteenth century and is linked in historical accounts to Jean Saint-Marc du Latourblanche, a treasurer-general under Louis XIV. After the French Revolution, the property passed to Pierre Pécherie. A later owner, Frederic Focke, helped raise the reputation of the wines. Focke’s German and Rhine-related background has led to historical accounts crediting him with helping establish or popularize the production of sweet white wine in Sauternes, although the region’s wine history developed through a broader set of producers and conditions. The estate received the distinction of Premier Cru Classé in the 1855 classification, a status that remains central to its positioning. La Tour Blanche farms approximately 65 hectares. The vineyard is primarily planted with Sémillon, supported by Sauvignon Blanc and Muscadelle. The estate also maintains smaller plantings of red varieties, including Merlot, Cabernet Franc and Cabernet Sauvignon. Its principal wine is Château La Tour Blanche, produced in an average annual volume of about 4,000 cases according to the referenced material. The estate also makes Les Charmilles de La Tour Blanche as a second wine, with average annual production of about 1,250 cases. Smaller-volume labels broaden the portfolio beyond the flagship sweet wine: Les Jardins de Thinoy and Isis are dry white wines, Osiris is a demi-sec wine, and Cru de Cinquet is a red wine. The brand is positioned at the intersection of classified Bordeaux heritage, Sauternes terroir and specialized sweet-wine production. Its state ownership and school function distinguish it from privately controlled neighboring estates, while its Premier Cru Classé status supplies the principal historical and quality credential. The wines are associated with the international market for premium Sauternes and other fine Bordeaux wines, although publicly available reference material does not establish a detailed current distribution footprint, sales profile or financial scale.
History
The documented history of Château La Tour Blanche extends to the eighteenth century. Historical accounts associate the estate’s early identity with Jean Saint-Marc du Latourblanche, who served as treasurer-general during the reign of Louis XIV. The property changed hands after the French Revolution and was subsequently owned by Pierre Pécherie. During the nineteenth century, the German owner Frederic Focke played an important role in improving the estate’s reputation. His connection with the Rhine wine tradition has led to the historical attribution that he helped bring, or at least reinforce, the culture of sweet white-wine production in Sauternes. The estate’s reputation was formalized through the Bordeaux Wine Official Classification of 1855, in which Château La Tour Blanche was designated a Premier Cru Classé. The classification was created for the Paris Universal Exhibition and remains one of the most influential reference points for the hierarchy of Bordeaux wines. For La Tour Blanche, the designation established a durable link between the estate, Sauternes and the international market for highly regarded sweet wines. After Focke’s death, the estate eventually came into the possession of Daniel Iffla, known as “Osiris.” Iffla was associated with a number of philanthropic and patriotic activities. In his will, he left La Tour Blanche to the French state, subject to the condition that it be used as an agricultural college. This bequest made the estate exceptional among classified-growth properties: rather than remaining a conventional privately held château, it became a public asset with an educational mandate. The La Tour Blanche School of Viticulture and Oenology began operating from the estate in 1911. Since then, the property has combined two related functions. It continues to produce wine under the La Tour Blanche name, while also serving as a training and educational institution for people preparing to work in viticulture, winemaking and related wine-industry professions. The school’s presence connects the estate’s historic vineyard to practical instruction and preserves a direct relationship between teaching and commercial production. The vineyard covers approximately 65 hectares and is dominated by Sémillon, which represents about 83% of plantings in the referenced description. Sauvignon Blanc accounts for approximately 12%, while Muscadelle accounts for about 5%. These varieties support the production of Sauternes-style sweet white wine, in which selective harvesting and botrytis-related concentration are central to the finished style. Smaller areas are planted with Merlot, Cabernet Franc and Cabernet Sauvignon, allowing the estate to produce a red wine in addition to its white-wine portfolio. The principal cuvée is Château La Tour Blanche, with average annual production reported at approximately 4,000 cases. The second wine, Les Charmilles de La Tour Blanche, averages approximately 1,250 cases. The estate also produces smaller quantities of Les Jardins de Thinoy and Isis as dry white wines, Osiris as a demi-sec wine, and Cru de Cinquet as a red wine. Together, these wines demonstrate a portfolio broader than the flagship classified sweet wine while retaining Sauternes and the estate’s vineyard identity as its central reference. In contemporary terms, Château La Tour Blanche is defined by the combination of four attributes: its Sauternes location, its Premier Cru Classé status, its focus on sweet white wine and its ownership by the French state. The school and winery operate as linked parts of the same estate, making La Tour Blanche both a Bordeaux wine brand and an institution connected to professional wine education.
