Tane Koji / Koji Starter

This Kosher-Certified Koji spore is used by Shochu distilleries in Japan. These spores are Aspergillus luchuensis.

Koji made from White Koji Spores has a sweetness from the rice decomposition and a sour taste from the naturally-occurring citric acid. The color of the spore itself is somewhere between off white to eggshell color, and the finished Koji has a white color and a beautiful appearance.

You can enjoy a sour taste amazake from the Koji made from these spores, which makes a perfect summer drink.

Instructions:
1. First stage (after applying the koji spores): Maintain the koji temperature within 37~38℃

2. First maintenance (18~20hr after applying the koji spores): Maintain the koji temperature within 35~38℃

3. Second maintenance (25~27hr): Maintain the koji temperature within 35~38℃

4. Third maintenance (30~32hr): Bring down the koji temperature within 32~33℃ and maintain the temperature until completion.

5. Completion: 42hrs after applying the koji spores.

*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, if the yellow koji spores leftover exist, yellow koji spores will suppress the black koji spores which also reduces 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 White 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.

Just ordered another for an additional car -- original purchase from 2022 still going strong.
Just ordered my 3rd to keep one in each car. Good unit. The first one I bought was in 2022 and still works great. Reasonable fast to inflate tires -- don't compare it to shop air or a gas station, but it's way faster than cheaper ones. Only negative, I think my daughter lost one somehow because I should have had enough! :-)

Easy to use tire pump
Has easy to read digital pressure gague. Has built in light for finding tire valve stem in dim garage. Hose is flexible and stores by wrapping around pump. Shuts off automatically when tire is at desired pressure. Pressure on pump matched readings on my car tire pressure readout. Pressure only shows half psi increments so it takes a while to see if the tire is inflating. Inflation is somewhat slower than the one this pump replaced but it gets there accurately eventually.

Nice tire sealant.
Size: 32 oz
This seems to work very well. I will say that it seems to be pretty important to move the wheel around as soon as you can to distribute the product within the tire. I was held up for a few minutes and the Liqui tube seemed to start to set up in one spot and made the tire out of balance so I had to work quick to get it to distribute to the other parts of the tire. It seems to have worked though and so far the tires are holding air very well. I will be interested to see if it lasts for a long time but so far so good.

This stuff works!
Size: 32 oz
I was sceptical but wanted to avoid replacing 2 rear tires on my zero turn mower. The tires were leaking air and had bad sidewall cracking. I found the use of the product to be easy and quick. I aired up the tires and rode around the yard a few minutes to distribute the product in the tires. It has been 4 days and both tires remain aired up. Previously both tires would already be flat within this timeframe. Excellent results for me!

Doesn’t work for a car Tire seal slow leak
Size: 16 oz
Does not work for a car tire. Had a slow rim seal leak. Out 32oz in still leaks the same. Do not buy. I got the one with fibers in it. It worked just fine. This does not work. Period. $30 wasted actually I purchased two so I wasted $60 when I could’ve bought probably a new tire
