collection. A new
material system.
Brew Tree is developing a platform of fermentation-grown cellulose materials designed to replace resource-intensive products traditionally made from trees, plastics, and animal leather.
Grown Leather
CELLULOSE COMPOSITE- FERMENTATION-GROWN
A flexible cellulose-based material grown through fermentation in as little as 7 days. No animals. No petrochemicals. The material behind our first collection.
Grown Paper
Cellulose grown into paper-like sheets with unique texture, strength, and natural character. Designed for packaging, stationery, and creative applications.
SHEET CELLULOSE - UNIQUE TEXTURE & STRENGTH
Grown Wood
A next-generation cellulose composite designed to mimic the strength and machinability of timber — without harvesting forests. Furniture, interiors, manufacturing.
SHEET CELLULOSE - UNIQUE TEXTURE & STRENGTH
The material,
made into objects.
Every piece is grown from bacterial cellulose — the material that gives paper its strength, leather its texture, and wood its grain. Designed to last years. Home compostable when you're done.
