Brewery-made Fresh Koji | 300g

(0)

¥800 JPY

Raw koji made seriously by a sake brewery. The authentic ingredient will transform your everyday cooking.

For those who want to make their homemade fermented foods even more delicious, such as shio koji, shoyu koji, amazake, homemade miso, and pickles. We deliver authentic raw koji, carefully cultivated by our sake brewery using the same methods and quality standards as for brewing sake.

The freshness and enzyme power are on a completely different level compared to dried koji sold in supermarkets. Please experience the rich sweetness and deep umami that can only be tasted with raw koji shipped directly from the sake brewery.

🏯 Why is "sake brewery koji" different?

In sake brewing, koji is the most crucial process that determines the taste of the sake. In our koji-muro (koji room), artisans carefully monitor the condition of the koji with their eyes, nose, and intuition, while managing temperature, humidity, and CO2 concentration 24 hours a day using IoT.

"First koji, second moto, third brewing." As this sake brewing proverb indicates, koji is the foundation of all flavor. This brewery-quality koji will arrive in your kitchen.

🍶 Fermented foods and dishes you can use it for

Usage	Features / Points
Shio Koji (Salt Koji)	Significantly enhances umami when made with sake brewery's raw koji
Shoyu Koji (Soy Sauce Koji)	Condensed umami, highly versatile as an all-purpose seasoning
Amazake (Sweet Sake)	Natural sweetness, smooth finish
Homemade Miso	High fermentation power, resulting in richly flavored miso
Pickles / Nukazuke (Rice Bran Pickles)	A secret ingredient that brings out the sweetness of vegetables

✨ Raw Koji's Overwhelming "Live Enzyme Power"

Dried koji undergoes heat treatment during manufacturing, which reduces enzyme activity. In contrast, raw koji's enzymes are still alive, making its ability to convert starches into sugars and break down proteins into amino acids (umami components) significantly different.

✅ Shio koji turns thick and creamy
✅ Amazake finishes with natural sweetness
✅ Miso and pickles ferment smoothly

"It tastes somehow better than usual"—that difference comes from the freshness and quality of the koji.

📦 Delivery and Storage

Raw koji is a fresh food. Please refrigerate immediately upon arrival and use as soon as possible. If not using immediately, it can be frozen (for approximately 3 months). Freezing preserves most of its enzyme activity.
