How to choose the perfect milk for homemade yogurt and kefir?
This is very simple. Take the cheapest whole (full-fat)dairy milk, with short shelf life, stored in a shop’s refrigerator.
If you have your own cow in the backyard, you will not have this dilemma and can start making yogurt and milk kefir straight way.
Always check the content of the milk and make sure that there are no any added ingredients, like flavours and other additives. You will definitely not be able to obtain yogurt with chocolate, vanilla, or strawberry flavoured milk. You will also not be able to obtain yogurt with any vegetarian milk except soy milk (in the natural way).
However, you can use homogenised and long-lived brands of milk, only if they are whole and they are free of preservatives and other added ingredients.
