White cheddar cheese is a popular variety of cheese, but it can sometimes be affected by mould. While some moulds are harmless, others can compromise the taste of the cheese. In addition to mould, white cheddar cheese can also develop white calcium lactate crystals, which are harmless and even desirable to some. These crystals are common in aged cheddars and other hard cheeses such as gouda and parmesan.
