Homemade cheese does not require secret knowledge. Agreed - many rules must be followed, but cheese was made hundreds and thousands of years ago, so a modern man can create delicious homemade cheeses if he wants to. The simpler ones, to be eaten quickly, and the maturing ones, the price of which in the store can be terrifying.
In a home cheese factory, we will not recreate the works of masters and classic cheeses, because who can process several hundred liters of milk at a time. However, we can successfully create cheeses in a given style and invent our own cheeses - which is very satisfying and I strongly encourage you to do so.
