“When I finally understood that the stuff on the supermarket shelves wasn’t real buttermilk, I started looking for an alternative. I found it! I’ve been making a fresh batch of buttermilk weekly for about 8 months now….Well worth the price, and incredibly easy to make.” ~Melanie

Product Reviews

I never used buttermilk as much as I do now. I have been making goat buttermilk and it works perfectly. Now anytime a recipe calls for milk and I think it’s appropriate I substitute my buttermilk with fantastic results. -Candace

I bought some buttermilk starter a couple months ago, and I haven’t bought anymore since! Carefully maintained you can continue the buttermilk indefinitely! I use this buttermilk for everything, even making butter, and you would not believe the difference in taste from store bought. It is unbelievable in fired chicken too! Now we can have it whenever we want. You’ll love this! -Honeytiger

Product Q&A

Q. Can I make sour cream with this kit too?

A. You can use buttermilk to make sour cream:

Use Buttermilk: Add 1-2 tablespoons of buttermilk or yogurt per cup of cream, cover lightly and allow to culture for 12-18 hours in a warm spot (70-80ºF). When the culturing process is complete, place the sour cream in the fridge to cool.

Q. what is the difference between buttermilk and Kefir?

A. Buttermilk and kefir are both essentially cultured milk products. They acidify the milk and enable thickening as the milk proteins coagulate (curdle).

Buttermilk starter consists of one strain of bacteria. Kefir grains include around 30 strains of bacteria and yeast.

Q. How long will the mother culture stay alive in the fridge or how long until it degrades? We seem to use buttermilk (primarily for sour cream) in spurts, usually with a few weeks in between batches.

A. The mother culture remains viable for up to seven days, and must be recultured during that time. If you use buttermilk less frequently than weekly, we do carry a direct-set buttermilk and sour cream culture that may be a better fit for you.
