When making non dairy kefir, you just need to be sure the non dairy milk has eight grams of carbohydrates to give the bacteria something to eat. It takes the sugars and makes it into probiotics for you. You don’t get the sugar but instead lots of healthy probiotics. If it doesn’t have eight grams of carbohydrates than you can add one teaspoon of date paste, or raw sugar, per quart. I have placed the recommended amounts for cashew milk in the recipe below.
Nut milk kefir tends to separate because of the water, but this is normal. It also doesn't get thick like milk kefir does, but you can just shake it and drink it! It has tons of benefits.
