How to ferment Mesophilic Yogurt: Viili, Matsoni, Filmjolk, Piima...

Mesophilic yogurts like Viili, Matsoni, Filmjolk, Piima have the advantage of being super fast and easy to prepare! They ferment at room temperature in just 24 hours (no yoghurt maker needed). Also, these cultures are sustainable and allow you to prepare many recipes.
If it's your first time fermenting this culture, your yogurt will reach the expected consistency after a few tries (2 to 5). It will probably be liquid the first few times. It's normal. Start again the recipe once a day until the desired texture is obtained.

  5. Let it ferment at room temperature.

  1. Check the preparation by slightly tilting the jar. If the consistency of the mixture is held in a mass, it is ready.
  2. Once the yogurt is in place, close the jar tightly and refrigerate 6 hours or more.
  3. The yogurt can be consumed after six hours, but don't forget to retain a little culture for your next recipe.

Plant-Based Milk Recipe

As these organisms have not evolved to feed off vegetable milk substitutes, they can only prosper for a few generations. For this reason, it is important to retain a small amount of dairy milk to use it as a catalyst to seed the soy milk, almond milk, sesame seed milk, pumpkin milk, walnut milk, coconut milk, sunflower milk or any other vegetable-based milk.

Before you start experimenting, we recommend that you grow yogurt with a dairy milk base for a few weeks. It will allow your starter culture to be strong enough.


  • To keep your culture healthy, prepare a new recipe at least once a week.
  • Avoid the culture becoming too sour because of a too long fermentation.
  • Fermented foods often have an acidic odor and taste. Never consume something that has an unpleasant smell, or taste.
