*If an incubator was used for the yellow koji spores (such as koji spores for rice, barley and soy source) previously, make sure that you sanitize the incubator very well. Otherwise, leftover yellow koji spores may suppress the growth of black koji and reduce citric acid production.

When using a wooden incubator, you can spray 70% proof Ethel alcohol, hydrogen peroxide or boiling water, then wipe it and wait until it’s completely dried. 

Size:
20g/0.7oz
(This can be used to make 10kg/22lb of Black Koji)

Shelf Life and Storage Information:
The expiration date is printed on the front label. Store at room temperature (59F°-77/ 15℃-25), avoid moisture and direct sunlight. Consume the product soon after opening. Any remaining spores should be sealed well.

Great product, great company!

I found some of this years ago and loved it. Ran out, couldn't figure out where to find more then this last Christmas my mother gives me some of the rose salve and I remembered how much I loved the lotion. So as I was looking for more of the rose salve (also AMAZING) I got some of the lotion. It goes on really light feeling, but has some serious softening abilities. I use the salve on my knuckles first then use like a Chick-pea size amount of the lotion overnight and my hands are great the next day, especially considering how much I've been washing my hands and using hand sanitizer these last few weeks. It smells like lemon meringue pie, and is more lightly perfumed than BBB stuff (which I love since I'm prone to headaches). I love CO Bigelow products, have yet to try one I dislike. I use the overnight lip balm in the winter or during colds when my lips crack and dry the most. I use the rose salve for my regular daytime lip balm (stuff is the duct tape of the salve world, no joke!) and for extra relief on any dry skin. Some might argue it's a little expensive for the size you get, but you don't need much of any of them so they last forever. I still have half a tube of rose salve lip balm from Christmas and I use it every day, several times. They all smell good, they all feel really clean on, they do what they're supposed to without adding products (like glycerin) that will cause further dryness or chapping. Thank you so much, CO Bigelow for making so many quality products and being so consistent with the quality for so long. Fan for life here!

Consistent Quality
Size: 1 Ounce (Pack of 1)
I've used this off and on for years and it's my favorite. I'm extremely picky with things I slather on my skin, and usually make my own from balms, oils, lotions etc. from scratch..with herbs infused for deep healing of skin and muscles. I didn't make enough this year so had to turn to store-bought. I'm not a fan of too many ingredients, and this lotion has more than I prefer, but it works really well if I need it. Winter skin, hands after doing dishes, etc..this lotion fixes it. It goes on, absorbs fast and feels light. The smell is great too. It's not overpowering and doesn't give me a headache like 99% of scented things do. I love this stuff, only wish it was cheaper. It's great, but the ingredient list isn't very good; it doesn't cost a fortune to make this.
