These create chemical reactions that cause it to change into a combination of solid " curds " and liquid " whey ". The whey is generally drained off, concentrated and dried into a powder. Variations in the amount and type of bacteria influence the taste and texture of the final product. Other aspects factor into the type of cheese that's produced: the salting method, its temperature and how long cheesemakers age it, which refers to the amount of time it is left alone to ripen and form.
