I love homemade whey, that cloudy liquid that remains after milk has been curdled or strained, and it can be used in many fermentation recipes. Whey contains probiotics which are “good” bacteria that is good for your health, especially your digestive system. 

I add whey to all of my fermented foods such as sauerkraut, ginger ale, ketchup, and pickles. Our ancestors always fermented their condiments; this gives them not only probiotics but digestive enzymes as well.

After two years of drinking beet kvass, my periodontist told me that my tooth pockets were smaller than they used to be. In the four years that I have now been drinking a shot glass with most of my meals, I have not been sick once.

How to Make Whey

To make whey, you have to have access to raw milk. That is the only kind of milk that I buy. Pour some of the milk in a glass jar and cover loosely to keep dust and other debris out of it. Leave on a kitchen counter for four to seven days or until it begins to separate. The warmer the room is, the faster it will separate.

Put a strainer over a bowl and place a piece of cheesecloth in the strainer. Pour the mixture through it.

The curds will stay in the cheesecloth and the whey will fall into the bowl. Refrigerate the whey until you are ready to use it.

The curds can be made into a spread by adding some chives, basil, garlic powder, turmeric or whatever other herbs you like to eat. 

This and many other how-tos and recipes can be found in my new book, Celeste’s Garden Delights. Enjoy!

As an inflammation sufferer I’d really like to try this as a holistic remedy. TBH I’m a little weary as a local health official warned residents of a recent salmonella outbreak last summer and urged against consuming unpasteurized dairy. Curious—is there is a way to ensure I’m not exposing myself or my family to unhealthy pathogens during the process of fermenting homemade whey?

whey from Stonyfield yogurt

A milky liquid separates from the curds of Stonyfield plain (whole milk) yogurt. It's not made from raw milk. Will this whey serve in making fruit kvas?

Hi David, Yes, you can use

Hi David, Yes, you can use that whey in fruit kvass. Good luck!


Hi there. I make Kefir Milk with grains. When the Kefir Milk is ready then I make smoothies or Kefir Cream Cheese. I have 12 Liters of Whey at present and need some ideas of what to do with it. I am using it to dilute fresh guava pulp so as to drink it. I read that you can feed it to your animals by adding a table spoon of it in to their water. Apart from using it as a Starter Culture in baking and fermenting, watering the plants what else can I do with it?

Hi Stephen, I use whey in

Hi Stephen,

I use whey in many recipes. It's an excellent addition to fruit and beet kvass (see blog), sauerkraut, ketchup, mayonnaise, and kimchee (see blog). It helps these foods to keep longer in the fridge.

Yogurt whey. After straining

Yogurt whey. After straining my home made yogurt to make Greek style yogurt. There is an abundance of whey remaining. I've found very little information as to it's uses. Any suggestions?
