The Chateau de Vallois wine estate is debating whether to preserve its luxury brand or extend its reach. Gaspard, the majority owner, must decide between his traditional view and his granddaughter Claire's proposal to produce a third, more affordable wine. Francois argues they lack the grapes for expansion, while Claire believes a lower-priced wine could attract young consumers and grow the brand. The estate manager Jean Paul's expertise could help determine if brand extension is feasible without compromising quality or relations with their negociant partners. Gaspard's final decision will set the family business's strategy for the future.
