Important Note: Rennets vary in their strength (ability to coagulate milk). Their ability to coagulate milk varies with the type of milk being used. To insure your milk coagulates property and in a timely manner, we suggest using calcium chloride, especially if you are using homogenized and/or pasteurized milk. Calcium chloride will also insure you attain a clean break, proper coagulation, and more yield. Mix the correct amount of rennet in a small amount of clean water before adding to the milk. Tablet and powder rennet can be mixed with a little clean water before adding to the milk. Dilute liquid rennet in a small amount of clean cool water. Store liquid rennet in refrigerator. Store powder and tablet rennet in the freezer. Store liquid rennet in the refrigerator. When adding any rennet to the milk, draw the rennet across your milk in one slow pour, and make 2-3 slow strokes to mix. DO NOT STIR.
