How to Make:

1. Get container, fill halfway with rice-wash. Rice wash is the water leftover when you rinse fresh rice. For example, go buy rice, whatever kind, bring it home, put it in a pot with warm water, swirl it a bit and then drain the [now milky colored] water. The water is now a rich source of carbohydrates. In this step, you can substitute rice with another carbohydrate source if you don’t have rice, as long as it is complex (don’t use simple carbohydrates like sugar, honey, syrup, molasses, etc). You can use wheat, barley, kinoa, other carbohydrates as the base to make your carbohydrate wash. This wash will attract microbes from the air, among them lacto bacilli.
2. Cover loosely and let stand for a couple days to a week
   • When is it done? When you see a light film on top (molds) and it smells a little sour and forms 3 layers. This is indicating the rice wash is infected with various microbes. This happens more quickly in warm temperatures because microbes are more active. Thus it is all relative since we don’t do this in controlled laboratory conditions.
3. The layers are distinct
   • Top layer: floating carbohydrates leftover from fermentation and possibly molds
   • Middle layer: Lactic Acid and other bacteria (cheese buffs will recognize this as a makeshift “rennet”). We will use this layer.
   • Bottom layer: Starch, byproduct of fermentation
4. Extract the middle layer using a siphon. This layer contains the highest concentration of lactic acid bacteria and lowest concentration of the unneeded byproducts
5. Get a new container, larger than the first. Take the extracted serum from the last step and mix it with 10 parts milk. By saturating with milk (lactose), we dissuade other microbes from proliferating, leaving L. bacilli. E.G. if you have 1cup of the serum, mix it with 10cups milk.

TIP: The best milk to use in unpasteurized natural milk. However, any milk will do, even powdered milk. In our experience, the best is unpasteurized natural but just use what is available. We just want to saturate with lactose to promote L. bacilli bacteria.

1. You want to keep this stage anaerobic as much as possible. You can use something like rice bran, barley bran, wheat bran, etc sprinkled on top of the milk. I use a sealed container with a one-way valve.
2. After about 1 week (temp dependent), you’ll see curds (made of carbohydrate, protein, and fat) on top of the milk. The water below will be yellow colored – this is whey, enriched with lactic acid bacteria from the fermentation of the milk.

NOTE: Microbes like L. bacilli are more active in warmer temperatures. The curds you see are a byproduct of the fermentation process. Fermentation is generally associated with microbial processes under anaerobic(no oxygen) conditions. Now, L. bacilli is a facultative anaerobe, that is it can live and work with or without oxygen, but less competition in anaerobic conditions.

1. The water below(whey+lacto) is the good stuff. You want to extract this. You can either skim the curds off the top, pour through a strainer, or whatever other methods to accomplish that

NOTE: Remember the curds, or byproduct of milk fermentation by L. bacilli, are great food. They are full of beneficial microbes like L. bacilli. Feed the curds to the soil, compost pile, plants, animals, humans – whoever wants them! They are full of good nutrients/microbes. No waste in natural farming.

1. To preserve at room temperature, add an equal part sugar/molasses to the serum. So, if you have 1L of serum, add 1kilo sugar or 1L molasses. Otherwise store in fridge to keep.

Example Recipe:

• 1 L rice wash
• 10L Milk
• 10kg sugar
• After rice wash and milk remove curds – around 1L
• = 20 L lactic acid bacteria serum
