Can you drink amazake while pregnant?
Check firstOnly the alcohol-free koji version is fine during pregnancy. The sake-lees type is made from leftover sake solids and can contain alcohol, so skip that one.
Why
Amazake comes in two forms that look almost identical in the cup. Koji amazake is made by letting rice ferment with koji mold into natural sugars with no alcohol produced, and it is sold as a non-alcoholic drink. Amazake made from sake kasu, the lees pressed out of sake, carries residual alcohol, often around 1 percent and sometimes more in homemade batches. The NHS is clear that no amount of alcohol is known to be safe in pregnancy, and NSW Health points out that fermented drinks marketed as low or non-alcoholic can still contain alcohol depending on how they are made. Read the ingredient list: if it says sake kasu or lists an alcohol percentage, put it back. Bottled koji amazake from a supermarket is also pasteurized, which removes any worry about the drink itself.
Safer alternatives
- Bottled Marukome koji amazake labeled non-alcoholic
- Hakkaisan rice koji amazake (alcohol-free)
- Warm pasteurized rice milk with a pinch of cinnamon and grated ginger
- Pasteurized Yakult or a shop-bought kefir drink for the fermented tang

Frequently asked questions
Does koji amazake contain alcohol?
Properly made koji amazake contains no alcohol, because koji converts rice starch into sugar without yeast fermentation. Commercial bottles are labeled non-alcoholic and are pasteurized. Trouble only comes from the sake kasu style or from homemade batches left to sit warm for days.
Is amazake from a Japanese festival stall safe?
Festival amazake is often the sake kasu kind, and stalls rarely label it. Ask which base is used, and if nobody can tell you, pass. Bottled versions from a store give you an ingredient list you can actually read.
I drank sake kasu amazake before I knew I was pregnant. Should I worry?
One cup of a roughly 1 percent drink is a very small amount of alcohol, well under a standard drink. The advice going forward is simply to stop, since there is no known safe level. Mention it at your next appointment if it puts your mind at rest.
