In October 2024, Maison Castel launched its Séries Limitées range on Reunion Island through a unique and charitable brunch. Hosted by Castel Réunion at the picturesque Villa Fleurié in the lush hills of Bellepierre, Saint-Denis, the event was set against a stunning panoramic backdrop. This special occasion also marked a collaboration with @srepen_reunion (Société Réunionnaise pour l’Étude et la Protection de l’Environnement), working together to help preserve the island’s natural heritage. Guests, including clients, journalists, and influencers, participated in a philanthropic auction of an exclusive six-bottle Séries Limitées set, with proceeds going to support SREPEN’s vital work protecting local biodiversity.
