Vegetable tanning: modernity meets traditional craftsmanship

In Manifatto Stories, Materials

Our great variety of manufacturers all have in common the use of eco-friendly, sustainably sourced materials.

An example of this honest and genuine approach to fashion and design is given by Carlo Ronchi’s products. Carlo’s bags and accessories are treated with the vegetable tanning technique, a traditional process born centuries ago in the heart of Tuscany.

Vegetable Tanning

Tuscany has always been a land of artists and artisans, a region with a long history and a rich cultural heritage. Here is based since 1994 the Consorzio Vera Pelle, a non profit organisation which protects the secular tradition of the vegetable tanning.


The artisans carefully dose the natural tannins extracted from plants and use the best water. Patience and time are the key of their work.


In Tuscany the vegetable tanning process is mainly made with plant extracts coming from chestnut, mimosa and quebarcho, a tree that grows in Argentina. Quebracho is a first class ingredient and brings warmth, perfume, softness and resistance to the leather. This is the secret of Carlo Ronchi’s creations: they never get old and their material improves with time.
