pH strips are a quick and easy way to check the acidification of your cheese and ferment.

In a lactic ferment and in cheese making beneficial microbes are underway to turn plant sugars and lactose into lactic acid.

For most cheeses timing of salting is really important; you want the fermentation to be just at the right acidity before you apply salt to slow it down.
