Fermented Berries

Fermented berries are a great way of getting more fermented foods and beneficial bacteria into your body.  Many people, when they first start eating fermented foods, have a lot of trouble getting used to the sour flavor of sauerkraut or kimchi.  These have a light sweetness and are often a good way to transition into eating more fermented foods.  They also make a wonderful, healthy dessert.

Fermented berries are a great way of getting more fermented foods and beneficial bacteria into your diet.
  • 3 cups of fresh berries (blackberries, blueberries and raspberries tend to work best) You can also use frozen.
  • 2 tablespoons of raw honey, organic sugar or rapadura (like this)
  • 2 tablespoons of whey (click here to learn how to make whey), ½ teaspoon of veggie starter culture (like this) or 1 acidophilus capsule (like this)
  • ¼ teaspoon Sea or Himalayan Salt
  • 2 tablespoons Spring or Filtered Water
  • 1 Organic Apple, a sterilized river stone, or a fermentation weight (like this)
  • 1 pint mason jar
  1. Rinse the berries and place in a bowl.

  7. Put the berries into a 16 ounce mason jar. Use a wooden spoon or something else to push them down.

  9. Pour the liquid over top.
  10. Fill a few inches from the top.
  11. The berries need to be completely submerged under the liquid.
  12. I used a large piece of an apple, but you can also use a river rock that has been sterilized in boiling water or a fermentation weight (see above)
  13. If you are using an apple, cut it into a large, round piece, big enough to fit into the top.
  14. Place the apple piece into the top so it is pushing the berries underneath the liquid.

    Fermented Berries - Push the berries down with an apple slice.

  16. If using a stone or a weight, place that into the top so the berries are submerged.
  17. Place the top on the jar.
  18. Only screw the top on halfway. As the berries ferment, pressure will build up so it is best not put the top on too tightly as it could explode.
  19. Place the jar on a plate in a case it leaks in a safe place.
  20. It will take 1-3 days to ferment, depending on how hot it is in your house. Make sure you don't ferment it too long or it will turn to alcohol.
  21. You can check periodically to see if it is done, by carefully opening the jar over the sink, and when it is bubbly, fizzy and less sweet, it is done.
  22. When it is completely done, take out and discard the apple pieces or take out the weight or the stone and clean them.
  23. It will keep in the refrigerator for around 6 weeks.
  24. You can serve this with yogurt, over ice cream, in a smoothie or just eat it plan.


7 Thoughts on “Fermented Berries

  1. I’ve been fermenting for quite a while, but I’ve never fermented fruit. I have some wild blueberries in my frig – I think this is a perfect idea for using some of them!

  2. Those do sound delicious. If only I could keep berries long enough (or get enough of them) for some of them to make it into a jar… My kids devour them on sight!

  3. These look really yummy! And the idea of using the apple to hold them down is BRILLIANT!

  4. Great idea! My girls would love this!

  5. I make sauerkraut all the time, but I never thought about fermenting fruit! I’ll have to try this.

  6. I love this recipe! I’m going to share and pin it now. YAAAY! 🙂
