Birte Jantzen – Organizer

Born in Hamburg (Germany) in 1970, she set off alone for France at the age of 21, armed with a strong spirit of exploration, 5,000 francs in her pocket and the ambitious project of conquering fashion and haute couture. In 2011, she discovered the fascinating world behind wine. Since then, she has trained in sensory analysis at Suze-La-Rousse University, obtained the WSET Diploma and taken courses in viti-oeno at the Hochschule Geisenheim University.

For 4 years, she was part of the team of critics for the Bettane & Desseauve wine guide. Since 2018, she has been writing for the German, French and Swiss wine press and also teaches French wine at Hochschule Geisenheim University. She divides her time between Germany and France, while spending most of her time in the vineyards.

Following numerous discussions with winegrowers, 2019 she decided to organise a conference dedicated to biodiversity in the winegrowing environment, named Vineyards & Biodiversity. Despite the ups and downs of Covid, the first conference was held in May 2022. This project was made possible thanks to the support of loyal friends, unexpected sponsors and a partner as audacious as herself: the Maison des Vignerons de Châteauneuf-du-Pape, co-organiser since the first edition.

Michel Blanc – Co-Organizer


Born in the Luberon region, his parents were winegrowers, arboriculturists and farmers. He initially trained in food engineering and biotechnology before specialising in export marketing and vine and wine law. Now director of the Maison des Vignerons de Châteauneuf-du-Pape, he is known for his dedication, his love of Grenache (he is a member of the Grenache Gang!) and his commitment to the environment and the agricultural world.

Since 2020, he has been managing Domaine Arnia with just as much passion, having taken over the family vineyards in AOC Luberon and AOC Ventoux.

Sarah Herly – Organizing Team


After studying Philosophy and spending the first part of her career in the Nantes gastronomy sector, Sarah initially worked in the promotion of cultural and institutional events.

A project opportunity in the wine sector led her into the exciting world of wine, and since then she has set up her own marketing strategy and business development consultancy, called Drink a Concept.

In parallel, she continues to think about new concepts off the beaten track, combining wine with the world of art and philosophy.

Marlène Angelloz – Organizing Team

After a first life as Communications and Operational Marketing Manager, Marlène Angelloz, aka Fan de Grenache, entered the world of wine in 2010. Since then, she has run the Grenache Association, which aims to promote this emblematic grape variety in France and around the world.

In 2019, she joined Chêne Bleu, a wine estate nestled in the heart of the Dentelles de Montmirail wilderness where biodiversity is not a marketing concept but a daily fact.

A champion organiser, she brings her experience to international events such as Areni Global, a think tank dedicated to Fine Wine.
