A new standard of luxury Brewed Protein™ fiber is a premium
Brewed Protein™ fiber is a premium, plant-based material produced using Spiber’s fermentation (brewing) technology, providing a circular solution and pioneering a new category of protein fibers.
Our protein fibers can be tailored to offer a silk-like sheen and delicacy, a luxurious smooth feel akin to cashmere, or the loftiness of high-quality wool.
Due to its plant-based ingredients and precision fermentation process, Brewed Protein™ fiber has the potential to significantly reduce environmental and animal welfare impacts compared to traditional materials.
