Grown,
not made
A new material company. Replacing forestry with fermentation.
WHY WE EXIST
What if we could make
the materials we need
without destroying the
ecosystems we love?
Food Waste
We start with organic waste that would otherwise go to landfill.
Fermentation
Beneficial bacteria ferment the waste into cellulose.
The Process
Cellulose
A natural, durable material is grown layer by layer.
Material
Dried, refined an prepared for craftsmanship.
Product
Thoughtfully designed goods for a better tomorrow.
More than a product
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.
