Rinse your seeds, but do not wash them. You want to promote the growth of beneficial bacteria present on the grains, so washing them away will defeat the purpose.
Soak your seeds in your jar overnight for 8-12h in twice the volume of filtered water. Fasten the sprouting lid.
In the morning, pour off the water.
Rinse and drain your seeds 2-3 times a day with filtered water for anywhere from 2 to 4 days. Their little tails will appear after a few days.
Add about 1 quart of filtered water to your jar. Secure it with a cloth lid.
Let the grains ferment for 2 days at room temperature.
Strain the beverage with the cheesecloth. Save the liquid and compost the sprouts.
Store the rejuvelac in your fridge to slow down the fermentation process. Drink within 5 days.
