Lait ribot is cultured buttermilk from Brittany in France. Made with whole milk, it is a thick and cheesy probiotic beverage. It is easy to make at home, provided you have some original culture from Brittany!


Units Scale
  • 1 liter of whole milk
  • 1/4 cup of cultured French buttermilk


  1. Mix milk and culture together.
  2. Leave it out on the counter for 12-24 hours. It is finished when it has a slightly sour taste and thicker consistency.
  3. Refrigerate until ready to drink.


  • French buttermilk is REALLY easy to culture. I tried several brands and they all worked well.
  • The process for culturing is identical to making fermented buttermilk in North America, but it involves different cultures. The flavor is less sour and more cheesy.
