The first bottle of Saint-Estèphe to bear the name of Château Petit Bocq was produced in 1972. Born on an estate that was just under two hectares, the wine showcased the finesse of Merlot grapes which largely dominated the blend at the time (80%).
The owner of Château Petit Bocq, Francis Souquet, an experienced winemaker and connoisseur of the Médoc’s terroirs, was none other than the head of vineyard management at Château Ducru Beaucaillou. Even in its early years, its undeniable quality was already praised by the likes of Ginestet and Parker.
The estate was acquired in August 1993 by Dr. Gaetan Lagneaux, a great wine enthusiast since his teenage years. He worked tirelessly and very diligently to expand the vineyard and improve the quality of the wine. Year after year, the property kept growing through the acquisition of old vine plots, most of which used to belong to the Marquis de Saint-Estèphe winery.
Château Petit Bocq was included in the Cru Bourgeois Supérieur ranking in 2003. Its label was redesigned and this is when the iconic ladybird appeared for the first time, a lucky charm of sorts that is still featured today. 
Now under a brand-new highly passionate team, Château Petit Bocq keeps working to fine-tune both its wine-growing and wine-making techniques, creating a bright future for the estate, while carrying on the legacy of its illustrious founder.
