About Brewed Protein™ fibers
Brewed Protein™ fibers are lab-grown, plant-derived, circular materials made through a proprietary microbial fermentation process. The fibers are a compelling solution to the growing demands of animal and petrochemical-free fibers to address numerous pressing environmental issues and risks. The potential environmental impact of a forward-looking Brewed Protein™ fiber production plan was found to be significantly smaller than cashmere and merino wool, largely due to the lower environmental impacts of inputs for Brewed Protein™️ polymer production (primarily plant crops and renewable electricity) when compared to livestock farming for cashmere and wool production. Production scale has been growing and Brewed Protein™️ fibers, yarns, and fabrics are now available for purchase at commercial scale.


The Balmacaan Coat featuring Brewed Protein™ material products will be available for sale at the following nanamica directly operated stores, the nanamica ONLINE STORE and the Marunouchi POPUP STORE (REGENERATIVE CIRCLE) starting from Friday September 29, 2023.
