Bulgarian yogurt is the most popular variety of yogurt in the world and is one of the things that make Bulgarians proud to call themselves Bulgarians; it is their exclusive invention and heritage that dates back many centuries. Bulgarian yogurt is thick, creamy and delicious.

CHILD APPROVED!

Child Tester says that this one is lovely, and that she would like to eat this with more vanilla in it, definitely honey over other sweeteners, and that it’s perfect in smoothies and served with fruit for TWO THUMBS UP!!

CAT APPROVED!

Linus the Foster Cat will gobble this one up before his kibble, and there are definitely TWO PAWS UP!! while he’s pawing at the fridge to make sure we don’t forget to give him some when this is what he’s been eating!

DETAILS

100% Organic Milk with Active Cultures

Our yogurt cultures are meticulously fermented with the highest quality organic dairy, ensuring that our probiotic products are not only delicious but also packed with the beneficial bacteria your body needs for overall wellness.

In the packet, you will find approximately 1/2 teaspoon of our premium Bulgarian culture. This ideal quantity ensures that you have enough to initiate the yogurt process twice, allowing for a second attempt if necessary (wink-wink).

Bulgarian yogurt is a type of thermophilic ferment. This culture contains certain bacteria that grow best at a consistent temperature, which can be achieved using a yogurt maker or similar device.

Ships dehydrated and does not include jars and other props.

This yogurt culture is made in a facility that also processes wheat, dairy and other possible allergens.

To minimize environmental impact and promote sustainability, we provide clear and straightforward activation instructions on our website, ensuring ease of access for all customers.

I’ve been making yogurt for years off of store bought and never had this great a quality of yogurt! I ordered this to see if it would help the issue I’ve been having with yogurt turning stretchy due to wild yeast and so far so good! It’s thick and creamy!

The instructions were clear and necessary to the entire process. I am making a perfect yogurt culture with this purchase. I'm very satisfied with my order and the wait time was minimal. My 4th batch of yogurt was perfect. 🤌
