What is Koji Amazake?
Koji Amazake is a traditional Japanese sweet drink made by fermenting cooked rice with rice malt (kōji)—a powerful ingredient rich in enzymes. Unlike sake lees-based amazake, Koji Amazake is completely non-alcoholic, dairy-free, and naturally sweet without any added sugar.
It has been enjoyed for centuries in Japan as both a comforting beverage and a nutritious, energy-boosting tonic.
Is It Really That Healthy?
YES—Koji Amazake is a gut health powerhouse.
It’s often called “drinkable IV” in Japan thanks to its impressive nutritional profile:
Rich in digestive enzymes like amylase and protease
Contains B vitamins (including B1, B2, B6, and folic acid)
A source of fermentable dietary fiber, which helps support the gut microbiome
Full of natural glucose, created by breaking down rice starch—not added sugar
My Personal Connection
I turned to Koji Amazake after experiencing chronic gut issues and the devastating loss of my brother to colon cancer in 2024. In my healing journey, I discovered that traditional Japanese gut health wisdom like chōkatsu (腸活) gave me strength and clarity. Koji Amazake became more than a drink—it became part of my self-care, emotional nourishment, and connection to my culture.
Gut Health Benefits of Koji Amazake
Supports Digestion: The enzymes help break down carbs and proteins, reducing the burden on your digestive system.
Feeds Good Gut Bacteria: The natural fiber in amazake acts as a prebiotic, encouraging healthy gut flora balance.
Stabilizes Energy: Koji Amazake contains natural glucose that’s absorbed slowly, giving you sustained energy without a sugar crash.
Improves Nutrient Absorption: Enzymes help unlock nutrients from food, making your body more efficient at absorbing them.
Soothes the Gut: Thanks to its anti-inflammatory compounds, Koji Amazake may calm irritated digestion.
How to Use Koji Amazake
Koji Amazake is versatile! You can:
Drink it chilled or warm
Mix it with smoothies or yogurt
Use it as a natural sweetener in baking or sauces
Stir it into oatmeal or cereal
Replace sugar in your favorite recipes
I love adding it to my Soy Milk Hōjicha Latte for a relaxing, gut-friendly treat.
Watch Out for These!
Storage: Keep refrigerated and consume within 5–7 days once opened.
Check Ingredients: Make sure it’s made only with rice and rice koji—no added sugars or preservatives.
