The winery is located in the municipality of Bommes in the area Sauterne (Graves, Bordeaux). It was founded towards the end of the 18th century by Latour Blanche. In 1815 it was taken over by the German -born Frederic Focke, who is said to have experimented with noble-rotten berries. By the well-known German wine collector Hardy Rodenstock (1941-2018) organized tastings supposedly the vintages 1747 and 1748 as noble sweet Wines have been recognized. This would give the winery the honor, even before the famous Château d'Yquem to have produced sweet wines. This is not guaranteed. The estate was at the Bordeaux Classification Classified in 1855 as "Premier Cru Classé" (Sauternes).
The later owner, Daniel "Osiris" Iffla (1825-1907), bequeathed the estate to the French state in 1909 on the condition that it establish a viticulture college "École de Viticulture et d'Oenologie de la Tour Blanche". In honor of the founder, his alias "Osiris" is mentioned on the label. The estate is still under the administration of the Ministry of Agriculture. The vineyard area totals 40 hectares, of which 36 are hectares Sémillon (78%), Sauvignon Blanc (16%) and Muscadelle (6%). The extremely long-lasting noble sweet wine will be 18 to 24 months in 100% new barriques expanded. The second wine is called "Mademoiselle de Saint Marc". It also produces a dry white wine called "Les Jardins de Thinoy". Of the remaining four hectares, the red wine "Cru de Cinquet" is produced.
