SHOPPING TIPS |
KOJI AMAZAKE:
Make Your Own Amazake at Home
Whenever possible, I recommend making Amazake at home. With just rice koji, rice, and water, you get fresher flavor and full control over ingredient quality.
If homemade amazake isn’t for you, you can still find high-quality options at Japanese grocery stores.
Hakkaisan’s Koji Amazake uses only high-quality rice koji and water made in Niigata, Japan, without added sugar or unnecessary ingredients. You can often find it at Japanese grocery stores.
Choose the simplest ingredient list possible — quality matters.
KOJI AMAZAKE ON AMAZON:
If you don’t live near a Japanese market, you can still find it on Amazon — but always check the ingredient list to ensure there are no added sugars or additives.
RECIPE NOTES |
Keep in the fridge for up to 4 days—make a batch for the week!
For dairy-free options, substitute plant-based yogurt or milk (soy or almond) instead of Greek yogurt.
Adjust sweetness naturally with fruits like berries, peaches, or persimmons.
FINAL THOUGHTS |
Overnight oats are already a time-saving breakfast, but with the addition of Koji Amazake, they become a gut-healing powerhouse. Whether you prefer fruity sweetness or savory avocado, this recipe makes it easy to enjoy gut health every morning.
