An innovative protein material made using Spiber's bioengineering technology. Due to its plant-based ingredients and resource-efficient production process,
Brewed Protein™ fiber has the potential to significantly reduce environmental and animal welfare impacts compared to conventional materials.

Protein
Engineered at the molecular level, the protein is specifically designed and produced for premium textile applications.

Plant-based
Sugar from sugarcane is the primary ingredient used in protein production. In our plant in Thailand, Spiber procures sugar certified by a leading global sustainable platform for sugarcane.

Circular
Brewed Protein™ fibers can be broken down into nutrients and re-used as feedstock for the production of new Brewed Protein™ materials (demonstrated at lab scale).

Next-generation fiber
Engineered at the molecular level, the protein is specifically designed and produced for premium textile applications. Their fine and scaleless nature contributes to a smooth appearance and enhanced comfort.

Responsibly designed
Due to its plant-based ingredients and resource-efficient production process, these fibers have the potential to significantly reduce environmental and animal welfare impacts compared to conventional materials.

Degradability
Brewed Protein™ fibers have demonstrated biodegradability in marine environments and degradability in soil environments.

Wool x Protein
— A new texture, both supple and strong, is born here. —
Our 160 years of expertise in wool development meets Spiber’s groundbreaking biotechnology,
merging two materials born from the gifts of nature.

Gentle on the skin, wrapped in a new kind of comfort.
Made from protein—the same building block found in human skin—this next-generation fiber offers a supple yet resilient touch that gently embraces the body.

The Evolution of Basics.
Blending with the sensibilities of Japan Design, these fibers create a “new basic” that harmonizes with everyday life while making a subtle statement. They are ideal for minimal and modern expressions that highlight the individuality of the material.

From Nature to the Future.
Animal-derived wool and a next-generation fiber made from plant-based ingredients—both born from nature’s bounty—open up entirely new possibilities for expression.
