“Still making yogurt from the starter I got three years ago. It took two or three batches to get a really good, thick consistency. It's so much easier to make without all the hassle of a yogurt maker or keeping milk warm.”

A MOM'S REASON. OUR STANDARD SINCE 2002.

It started with a simple question:
What am I feeding my children?

Cultures for Health was founded in 2002 by a single mom who wanted to feed her children the best food she could.

That care still shapes what we make. Food-safety testing is a meaningful investment, and one we keep making for the families who bring our cultures home.

    So EASY!

    With most yogurt cultures you have to wait until the milk heats to 160 °F then wait some more while it cools back down to 110 F Not with this! No pots of milk to heat and no thermometer to watch. I took one star off only because I'd like it to be a little more thick. However, it has a mild taste and I love how easy it is to make.

    Thanks for sharing your experience, Vic! I understand your wish for a thicker consistency—maybe straining it a bit could help. Either way, it's awesome that you enjoy the mild taste and simplicity!

    Love it!

    The secret to thick yogurt is to use half and half instead of milk. I like the mild flavor of the Finnish culture. For those who want a tangy flavor, try one of the Greek cultures. Unfortunately Greek cultures are not mesophilic and will require a yogurt maker or some other way to keep the yogurt warm during fermentation.

    Still making yogurt from the starter I got three years ago

    It took two or three batches to get a really good, thick consistency. I love the mild flavor because then I add different flavored extracts and fruit as the mood strikes me. It's so much easier to make without all the hassle of a yogurt maker or keeping the milk warm after adding cultures. I tell all my friends about it!

    Easy to make and delicious.

    Before you start.

    Good questions.
    Plain-English answers.

    What comes in the bag?

    Two packets of Viili yogurt starter culture and instructions. Start with one packet and keep the other for later.

    What is Viili like?

    Viili is a Finnish yogurt with a mild, creamy flavor and a fairly thick consistency. Enjoy it on its own or use it in yogurt recipes.

    Do I need a yogurt maker?

    No. Viili cultures at 70°–77°F on your countertop. Choose a spot that stays in that range.

    How do I make more yogurt?

    For your first batch, mix one packet into 1 cup of cold pasteurized whole milk. Once activated, use 1 tablespoon of finished yogurt per cup of milk, up to half a gallon per batch.

    What milk should I use?

    The included guide recommends pasteurized whole milk and avoiding ultra-pasteurized or UHT milk. This culture contains milk and is not vegan.

    How long does it take?

    Check your first batch after 12 hours at 70°–77°F. If it hasn't set, the guide says to check every few hours for up to 48 hours. Refrigerate for at least 6 hours before enjoying.

    What if my first batch looks different than expected?

    The first batch activates the dried culture. Check the included guide and contact our fermenter support team if you have questions about your batch.

    What are the ingredients and allergens?

    Organic milk and dehydrated live cultures. Contains milk. Manufactured in a facility that also produces products containing soy and dairy. Labeled gluten-free and non-GMO.

    How should I store the unopened culture?

    Refrigeration is recommended; use by the date on the bag.

    How does shipping work?

    Free standard shipping is available on qualifying orders of $49.99 or more to the contiguous U.S. Other shipping rates are calculated at checkout. Discounts may affect eligibility; non-contiguous destinations have separate rates.
