Located in the southern Drôme region, Terra Provence was founded by Hans-Ulrich Wentzler, familiarly known as Ulli. His attraction to the sunny south of France led him to the Baronnies region in the late 1970s, where he met local lavender growers. He soon made friends with them and developed a business picking and producing distillation of the region's aromatic and medicinal plants, which he delivered as far away as Germany in his 2CV!

The idea of setting up his own company was born in his mind and took shape in 1989 under the name Wentzler.

Then came the time of travels and encounters: first Morocco in 1990, from where he brought back orange blossom floral water, then Portugal, where he met producers of verbena and eucalyptus. Then came Turkey, Sri Lanka, Somalia, Egypt... With each visit, bonds of trust and solidarity were forged. The man who today would be described as "baba cool" is a friend of peace, and seeks to understand how to preserve our Earth for future generations. For him, organic farming was a matter of course: man and earth must live in harmony. So, in 1991, he founded Terra Provence, a forerunner in organic farming! Faithful to his convictions and to the organic spirit, he paid for the first organic certifications for producers; this spirit was to be the guiding principle in the relationship between Terra Provence and the farmers.
