Activating a mesophilic yogurt culture

Activating A Mesophilic Yogurt Starter (Viili, Matsoni, Filmjolk, Piima)

Viili, matsoni, filmjolk or piima are all "mesophilic" yogurts, meaning that they thrive in moderate temperatures.

In addition to being delicious, these yogurts have the advantage that they can be prepared at room temperature and without a yogurt maker.

In comparison, regular yogurt needs heat to thrive.

Also, these cultures are sustainable and allow you to prepare many recipes!


How To Activate A Mesophilic Yogurt Starter

Dehydrated starter retains its qualities for a very long time, but to use it, you must activate it first.

  • Preparation time: 5 minutes
  • Fermentation: 48 hours


Equipment Needed

  • 1 pouch or pod of mesophilic yogurt starter (try viili, or matsoni)
  • 1 glass jar, with cloth cover and rubber band
  • 250ml of fresh pasteurized whole milk
  • 1 stainless steel tablespoon

Note: Our viili and matsoni starters contain three capsules. Use only one per recipe. You can store the others in the fridge.



  1. Put the culture pouch or the pod and a small amount of milk in the jar.
  2. Mix thoroughly (taking care to break up all the pieces).
  3. Add the rest of the milk.
  4. Cover the jar with the cloth and rubber band.
  5. Let ferment at room temperature.


After 12 Hours

  1. Check by tasting. If necessary, continue fermentation and observe from time to time.
  2. As soon as the mesophilic yogurt is ready (or at the latest after 48 hours), refrigerate the jar for at least 6 hours after sealing it hermetically.
  3. After 6 hours, the yogurt can be consumed. Don't forget to save a little culture for your next recipe.


Congratulations! The yogurt you have just prepared can be used as a base (also called "starter") for your next recipe. The amount to keep to start your next recipe is 1 tablespoon per 250ml of milk.

Important! The yogurt will reach the desired consistency after a few tries (2 to 5). It will probably be liquid the first few times. This is normal. Repeat the recipe once a day until the desired texture is achieved.
