Step 3: Feeding the Grains
A. Simply place them in a sterile jar and fill with milk!
*Make sure the jar is big enough to have atleast a couple inches space between the milk and the lid. A quart jar typically works well. Also make sure there is no soap residue - antibacterial soap will damage the bacteria in the grains.
*A good ratio is about 1 teaspoon per 1 cup milk in the summer and 1 tablespoon per 1 cup milk in the winter (it simply ferments faster in the summer - more on this in later steps).
