French organic sourcing in the heart of the Auvergne-Rhône-Alpes region:
As we are determined to offer the best of nature by proposing top quality ingredients, we have expanded our product range of red vine. These new « Made in France » ingredients have been developed in collaboration with small producers based in the aromatic and medicinal plants heartland. Based on the geographical proximity with our partners, you can visit the fields where the raw materials come from and discover the background of your botanical ingredients.
It is essential to know the species in order to make quality ingredients. This why we let our producers determine the ideal moment for harvesting the leaves. Raw materials are picked by hand in the autumn after the grape harvest (October/November) at certified organic vine growers. In fact, the highest content of principle actives is found when the leaf turns red, between the harvest and the leaves falling  . Drying is carried out naturally in line with climatic conditions.
Orders of the raw materials are made in February and the leaves are processed into botanical ingredients in our factories in Lozanne and Soyons in France, close to our producers.
