Koji is LIFE

Way more than just the spore...

Welcome to The Koji Shop, where tradition meets craftsmanship. We specialize in creating handmade equipment designed specifically for cultivating koji. Each piece is made to order in our Hudson Valley Cooperage, using high-quality, untreated wood to ensure a natural, chemical-free environment.

From inoculation to fermentation our traditional wooden products can assist you in your process. Whether you’re brewing sake, crafting soy sauce, or making miso, our pieces provide the perfect environment for your fermentation journey.
