What is yogurt whey?
Whey is that yellowish liquid that rises to the top of yogurt. Many people stir it back in, but I prefer to drain it off. The result is Greek yogurt and lots of leftover whey.
Can I use yogurt whey to make more yogurt?
YES! Add 2-3 tablespoons of whey to 2 quarts of heated and cooled milk. (More or less whey may also work–this is just what I do.) Whisk it well and incubate as usual.
In the picture below, I made the yogurt on the left with whey as the starter. I made the yogurt on the right with my homemade yogurt as a starter. The results were identical in taste and texture.
Why you might want to use whey as a yogurt starter:

2. You won’t have to “waste” any of your precious homemade yogurt by using it as a starter.
Instead, you can enjoy eating every last drop.
3. Always save a little whey to make your next batch.
Consequently, you won’t have to worry about keeping some yogurt back to use as a starter. It’s also good insurance if somebody inadvertently eats the last of your previous batch of yogurt.
4. Perfectly smooth texture
If you use a grainy or lumpy yogurt as a starter, you are sure to make more grainy or lumpy yogurt. Start over again by using whey.

FAQ about Yogurt Whey Used as Starter
1. How long does yogurt whey last?
I get a lot of questions on this subject. In my experience, it’s good for at least three weeks, but I’ve read it can last for six months. Although it may last longer, since I make yogurt twice a week, there’s no reason for me to keep it around.
The next question is related to this question but not the same.
2. How long does whey stay fresh enough to use as a starter?
Use a traditional yogurt starter at least once a week to ensure the most vigorous starter. I’m assuming the same goes for whey.
