The Sergent family boasts a rich vine-growing legacy in the Vrigny region, dating back to at least the mid-nineteenth century. Traditionally, they produced and bottled wines at the local cooperative, carrying the Roger Sergent label. Guillaume's father built a loyal following until 2008 when Guillaume and his brother assumed control of the family estate. In the typical fashion of generational transitions, the family holdings were divided. Guillaume retained approximately 1.5 hectares, while his brother, who now supplies fruit to Moët, received the remaining 2 hectares.

Vinification in 228L and 500L oak barrel, dosage generally under 5g/L.
