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 views and his granddaughter Claire's proposal to produce a third, more affordable wine. Francois questions if there are enough grapes and resources for a new product. The estate risks losing its negociants but could attract younger customers and extend its brand by entering a new, lower price market segment. Gaspard must determine the best path for future generations at the estate.
