A great way to preserve and use your abundance of blueberries is to make fermented honey blueberries. This super simple recipe has tons of health benefits and the sweet taste of summer. It only takes two ingredients and a little time.
Raw Honey Benefits
Raw honey is thick and sweet and has many health benefits. Pasteurization kills off the good bacteria and benefits of raw honey, making it unable to ferment.
These are some of the wonderful properties of raw honey:
- antioxidant
- immune boosting
- antibacterial
- prebiotic
- good for gut health
When infused with herbs, berries, and other ingredients, raw honey becomes even more of a powerhouse! Making infused honey is an easy way to boost its benefits, like this lilac flower infused honey or pine needle infused honey.
However, my favorite way to use raw honey to its highest capability is to ferment it! Fermented honey garlic and fermented honey cranberries are mainstays in my household.
This recipe for fermented honey blueberries is so simple, and only takes two ingredients. It will become a new favorite for sure!
Blueberries are full of vitamins and antioxidants and have an amazing, earthy, sweet summer flavor. Paired with raw honey and the probiotic benefits of fermentation, they make the healthiest snack ever!
Note: Since this recipe uses raw honey, babies under one year should not eat fermented honey blueberries.
Fermented Honey Blueberries
This recipe is super simple and is the best way to ferment blueberries. The main ingredient, as with all ferments, is time! It’s a sweet season for a berry ferment.
If you have tons of blueberries to use in their ripeness window, it’s easy to make a second or third jar of these! It’s delicious enough to gobble up, or you could share it with friends.
Otherwise, you can freeze any extra berries to preserve them too. Blueberries do great in the freezer. Or make no sugar blueberry jam!
Ingredients
Blueberries: Either homegrown, bought at a farmer’s market, or your favorite local produce store. They should be abundant mid-summer!
Raw honey: It’s important to use raw honey for this recipe, as it contains all the bacteria and wild yeast necessary for fermentation.
How to Make Blueberry Fermented Honey
First, place the blueberries into a wide-mouth pint-sized mason jar. Make sure to leave an inch or so of space at the top of the jar.
Then, add enough honey to cover the blueberries completely. Rock the jar a little to be sure the blueberries are all coated with honey.
The small amount of juice from the blueberries will create just enough liquid for fermentation to happen, so no other liquid is required.
The blueberries will float, but that’s okay—no stress! As long as they’re coated in the honey, they should be good to go.
Place the lid on the jar loosely, then tuck it into a dark place out of direct sunlight. A pantry, a shaded corner of a kitchen counter, or a cabinet that you open daily are all good choices.
Note: If you are using a metal lid, make sure to put parchment paper in between the jar and the lid. Prolonged contact with metal in a ferment can corrode the metal and leach it into your ferment.
Every day or so, tighten the lid on the jar and flip it upside down to coat the blueberries with honey again. Then, loosen the lid again when you return it upright.
Signs of Fermentation
It’s a good idea to have a plate under the fermentation jar. Sometimes, honey ferments bubble and leak out, which creates a pretty sticky situation. That didn’t happen for me with this one, but it can.
Within a few days to a week, you may start seeing small bubbles start to form on the surface of the honey. Woo hoo! This means things are going well, and the ferment is fermenting.
The blueberry honey will ferment for about a month, but you can eat it any time during the fermentation process. The flavor will continue to develop over time, with a sweet and earthy taste.
Expect the blueberries to shrivel a little bit and the honey to become much runnier. It will turn pink or purple in color, similar to the inside flesh of a ripe blueberry!
A Quick Botulism Note
Botulism generally isn’t a concern with this type of ferment, but If you are worried, use a pH test strip. Botulism spores can’t reproduce with a pH of less than 4.6. Honey is usually around 3.9, but that can vary between brands. Blueberries will also make the ferment more acidic.
If the pH is too high, add a splash of raw apple cider vinegar to add more acidity and retest. This is generally not needed, but I do want to mention it.
Regardless, it’s recommended that babies under a year old don’t consume raw honey.
How to Store and Eat Fermented Blueberries
Store the fermented blueberry honey in a cool place for many months or even a year, if not longer. Time is on your side with fermented honey!
These blueberries are delicious on their own as a health-beneficial snack, especially if you need an immunity boost. Or, take a spoonful of just the honey!
I like adding the blueberry honey to plain yogurt or even on top of ice cream. It’s also delicious drizzled on sourdough blueberry pancakes for an extra blueberry kick.
The honey can sweeten tea or top buttered toast. Use it anywhere you need a little bit of sweetness or a yummy blueberry burst!

I started this process and allowed the blueberries to ferment for about 5 weeks. The ferment worked perfectly!! The deliciousness is simply too good for mere words. I did not care for the shrivelled blueberries (after 5 weeks) so I kept just the honey. Now the trick is not to eat it voraciously until it’s all gone! I am now going to try other suggested honey ferments.

I have learned so much from your newsletter and social media platforms.
Elizabeth says
I made honey fermented blueberries once and ended up with mead. It was a delicious surprise.
Nonna says
I think this may be happening to mine. The liquid has become very thin and it bubbles like a warm beer. How do I handle it from here??
Cathy says
Hi. First off I’d like to say I absolutely love your newsletter and make a lot of your recipes. I’m very grateful.
My question is have tried to honey ferment aronia chokeberries this way? I’ve got a huge harvest this year. Thank you.
Grow Forage Cook Ferment says
Hi Cathy! I’m so glad you love my newsletter. I have not tried using aronia berries, but I’d imagine they’d ferment the same way. Give it a shot and let me know how they are!
