Yes, I’m over here fermenting blueberries tonight and super happy about it. If salty, sour blueberries don’t sound like your “jam,” let me assure you, you need to keep reading…
Fermenting Blueberries
Fermenting blueberries is a simple process that produces truly delicious results.
It is done in a sugary brine and both the berries and brine are delicious to use in so many ways. Add the immense benefits to your gut health and you really can’t resist these amazing little guys.

Fermented Blueberries
Ingredients:
- 2-2 1/2 cups of blueberries (about 300 grams)
- 1 tsp salt
- 6 tbsp of sugar
- 9 tbsp of filtered water
- 6 tbsp of kombucha (See notes below for alternative)
Directions:
- In a jar, add sugar and salt. (I used a tall, narrow mason jar.) Pour in warm water and stir to dissolve, then allow water to cool.
- Add kombucha and berries.
- Weigh down blueberries with a fermentation weight that fits inside your jar. I love this kit. All the fruit must stay below the brine.
- Add your ferment kit lid to the jar (or a loose lid, or a secured piece of fabric, if you don’t have this fancy kit). After 24 hours, taste a few times a day until your ferment reaches the desired taste. It won’t take long. (Fruit ferments faster than veggies.)
Notes:
- Any fermented starter would work. If you make cheese, use some whey; if you make water kefir, use some of the liquid.
- I use this salt, for the bonus minerals; use code SOULYRESTED for 15% off every order, every time.
- I used raw cane sugar; I have to research if I can use maple syrup next time.
- This fermenting kit has ingenious springs that do an amazing job keeping your food submerged in the brine and lids that keep your ferment breathing yet keep out what you don’t want in your ferment.
- If you don’t have a starter culture on hand, like kombucha, you can still ferment your berries, just grab this 6-pack of starter cultures. You’ll only need 1/2 of 1 packet for this recipe.
- If you’d like to know how to make your own kombucha, I got ya covered with everything you need to know about Simple DIY Kombucha.

Can you lacto ferment frozen blueberries?
I’m asked this a lot and I just need to try it, honestly, so I know for sure… I’ve only ever fermented fresh berries, but my hunch is that frozen will work almost as well. I assume frozen blueberries will be a mushier consistency but taste just as delicious.
What do lacto fermented blueberries taste like?
Fermented blueberries are a wonderful combination of sour, salty, and slightly sweet. I love them.

What is the purpose of the sugar? I’m diabetic, wondering if I can sub a 0 glycemic sugar like Bocha Sweet (from the kabocha plant) or just leave it out.
I thought ferments like this were made with the whey or salt solution, not sugar, which is how kombucha is made, but in kombucha no (or little) sugar is left.
Thanks for the recipe, LOVE blueberries, eat them daily. Good to know I can make them even healthier!!
Love the idea – but other than just eating them, what to you use the fermented blueberries in? And are they shelf stable? I imagine you have to refrigerate for the whole year???
That is the only downside, honestly… yes, you must store them in the fridge. But I use them anyway you’d use fresh blueberries, honestly. I love them on breakfast cereal or oatmeal and in my yogurt. Let me know what you think if you try them! 🙂
Michelle I definitely would be interested in using maple syrup if that’s possible.
My blueberries are 24 hrs in process. Couldn’t find just primary kombucha when I went grocery shopping but, I used
“GT Synergy “ brand in cherry/coconut/ lemongrass , seasonal item. Berries and cherries 🍒
Hi Susan, While I’m pretty sure maple syrup would work fine, I’ve never experimented with it… I never want to take a chance of messing up my beloved blueberries that I enjoy, in small amounts, all winter long. If you try it, keep me posted!
Michelle I figure other than strawberries other berries can be used in this recipe.
? What about stone fruit ?
good day michelle. I have a thought about replacing kombucha. i have collected over 3+ yrs : 3 ” of mother from braggs raw acv, could that possibly work in fermented blueberries. possibly more shrub tasting ? Awaiting your thoughts.
