Organic Milk Whey (Cow)

Whey the nutritious, protein-rich liquid expelled from curds during the cheesemaking process.
 
Whey (pronounced WAY) is one of the two main proteins in milk. It's the cloudy, yellowish liquid expelled from cheese curds during the cheese-making process and from straining fresh yogurt to thicken it. Whey can be either acidic, like that from yogurt and soft cheeses such as cottage or mozzarella, or sweet, which comes from harder cheeses produced with rennet, such as cheddar and Swiss.
