The producer
Why it matters.
Caviar de Sologne is an estate-scale French aquaculture identity with combined Grand Monarque brand and spring 2026 Sologne Osciètre menu evidence at Le Georges, plus current brand-level corroboration from Fleur de Loire.
The origin.
Caviar de Sologne is the public producer identity operated by Pisciculture Hennequart at Le Grand Cerneant in Saint-Viâtre. The aquaculture site raises sturgeon in the Sologne pond landscape and produces Osciètre caviar, with La Maison Nordique documented as a distinct commercial and product partner rather than an alias.

Caviar de Sologne Osciètre
The producer and La Maison Nordique identify the Osciètre product. At Le Georges, an official 2025 Grand Monarque page names Caviar de Sologne from Maison Hennequart and the spring 2026 menu separately names Sologne Osciètre; the product edge is the combined inference.
