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.

Chill, Strain & Save Some.

Cover with a tight lid and refrigerate at least 6 hours. Strain through cheesecloth for the thickest consistency, and reserve ½ cup for your next batch.

    First try didn't work :(

    Fortunately, this came with 2 packages of culture. I attempted with the first packet, but found that the bottom of the packet was not sealed or had torn. It didn't look like any of the culture had spilled out, so I thought I'd give it a shot. Unfortunately, nothing happened. I plan on giving the 2nd package a go in a couple weeks. Really want this to work as my wife and I fell in love with skyr while in Iceland for our honeymoon! Hopefully I'll be able to update this review with any progress!

    I recommend this product

    easy to make, mild flavor, very versatile

    I love this versatile yogurt, it's so mild I can use it for cooking, baking, and I even make it with half and half and strain it until it makes an easy spreadable cheese

    Tastes Like Cheese

    It didn't turn out as I expected, based on buying the "Icelandic Skyr" yogurt. It is fine if you are wanting a soft cheese, like cream cheese.

    Before you start.

    Good questions.
    Plain-English answers.

    What comes in the bag?

    Two packets of Skyr yogurt starter culture and instructions. Start with one packet and store the other in the freezer for later.

    Is skyr yogurt or cheese?

    Technically it's a fresh Icelandic cheese, which is why it's so thick. In the U.S. it's sold and eaten like yogurt, usually with berries, jam or other sweet toppings.

    Do I need a yogurt maker?

    No. Skyr cultures at 70°–77°F on your countertop, so you only need a spot that holds that range.

    Do I need rennet for my first batch?

    No. Activate the first packet in 1 cup of cold pasteurized whole milk. Later batches use ¼ rennet tablet dissolved in ¼ cup cold water for 2 quarts of milk.

    How do I make my first batch?

    Mix one packet into 1 cup of cold pasteurized whole milk. Cover and culture at 70°–77°F. Check after 12 hours, and continue checking up to 48 hours total until set. Cover and refrigerate at least 6 hours, then save ½ cup for the next batch.

    What milk should I use?

    The guide calls for pasteurized whole milk and avoiding ultra-pasteurized or UHT. Skyr is often made with skim milk; the rennet is what creates the thickness.

    How do I make my next batch?

    Reserve ½ cup of finished skyr to start the next 2-quart batch. If a batch doesn't set, the guide says to repeat the activation steps using 1 Tbsp of your previous batch in 1 cup of milk.

    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?

    Keep unused packets in the freezer and use them 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.
