Historical importance

Sorghum is an annual grass, which “colorans” variety used in Africa for dyeing, was found in old archaeological layers thousand years.
The dye from the sheaths surrounding the stem was used for leather, cotton and herbs rushes dyeing, but also as body paint, tinting gourds and masks in southern Benin and Nigeria.

In the 19th century this dye was exported to Europe under the name of “Carmine Sorghum.”
The two breeds of Sorghum bicolour African the most used for their coloring properties (dyeing, food and cosmetics) are caudatum and kafir.


The sorghum plant extract consists of a mixture of flavonoids anthocyanidins group, found in free forms, glycosylated, and methoxylated or condensed tannins.

Crop production – Manufacturing

We grow Sorghum in Poitou-Charentes (France). Harvesting is done at the beginning of autumn: after removal of spikes, stems and leaves are dried and finely crushed prior to extraction of the dye.

We carry out the production of plant extracts, pigment and pigmented oil in France.
