Who is Maria, the founder?
Maria Kumessa’s journey began with a simple passion: a love for wine and the art of French hospitality. After years of managing establishments and earning a Master’s degree in Management, she realized that her true calling was to share the elegance and joy she found in every carefully poured glass and every perfectly set table.
Since 2019, Maria has immersed herself in the world of oenology, constantly learning and exploring its endless wonders. Along the way, she earned recognition as a French Wine Ambassador from the École des Vins et Spiritueux and a Champagne Specialist Certificate from the Comité Champagne, but for her, these titles are just milestones on a much bigger adventure.
Through Grand Cru & Etiquette, Maria invites people from around the world to experience the beauty, sophistication, and unforgettable moments that wine and French culture can offer.
