Why Make a Fermented Cranberry Sauce?

You can certainly make a traditionally cooked cranberry sauce for your holiday table. I even have a tasty Orange Cranberry Sauce recipe to share with you.

But why not take your cranberry sauce to the next level? You can turn it into a probiotic-rich condiment that supports your gut health.

An Important Tip About Fermenting Fruit

Fermented cranberry sauce (or any fermented fruit for that matter) is amazingly delicious. It strikes the perfect balance between tangy and sweet for a pallet-pleasing combination.

When you ferment fruit, your fruit goes through three stages during the fermentation process:

  1. Lacto-fermentation
  2. Alcohol
  3. Vinegar

To enjoy your fermented fruit as a fruit, and not as an alcohol or vinegar, you need to catch it in the lacto-fermentation phase. But don’t worry. This is easy to do.

During days one and two of the fermentation process, you will begin to see a few bubbles starting to form. But by day three or four, your fermented cranberries will begin to bubble generously in their jar. This level of bubbling means they’re ready.

Keep this important timing tip in mind when fermenting fruit, especially when you’re making fermented cranberry sauce. I show you an example of the bubbles produced by fermentation, and I walk you through the fermentation process step-by-step in my recipe video.

How Do I Sweeten My Ferment?

When you ferment cranberries, you don’t want to add any additional sweetener at the start of the fermentation process. Otherwise, the added sweetener will accelerate the fermentation, and you are more likely to make cranberry alcohol than lacto-fermented cranberries!

So how do you sweeten your cranberries to turn them into Fermented Cranberry Sauce? Once your cranberries reach the lacto-fermentation stage, you will add sweetener to your cranberries. (You’ll want to use a whole sweetener like honey or Sucanat.)

Next, you’ll want to thoroughly mix the cranberries with your sweetener, decant your mixed cranberries in a jar, and refrigerate them.

When to Eat Your Fermented Cranberries

You’ll want to eat your refrigerated fermented cranberry sauce within a few weeks of making it. Even though your ferment is at a cooler temperature, the fermentation process will continue in your refrigerator, but at a much slower rate than when your ferment was resting on your kitchen counter.

Within about four weeks or so, you will most likely have what I call a “boozy” cranberry sauce since your ferment will most likely have moved into the alcohol stage.

So to enjoy a lacto-fermented cranberry sauce, be sure to make a small amount at a time and eat your fermented cranberry sauce within a few weeks of making it.

Answering Your Fermentation Questions

This delicious Fermented Cranberry Sauce is a probiotic-rich condiment that supports your gut health.


  • 1 quart-sized jar with a lid
  • 1 four-ounce jar or glass fermentation weight
  • 2 medium or large bowls


Ingredients Needed to Make Fermented Cranberries

  • 3 cups Cranberries, raw
  • 1/4 cup Whey Strained from plain yogurt or plain kefir.
  • 1/2 tbsp Coarse ground sea salt Reduce to 1/4 tbsp, if using fine ground sea salt.
  • Filtered water, preferably chlorine-free

Ingredients Needed to Make Fermented Cranberry Sauce

  • Fermented Cranberries from this recipe
  • 1/3 cup Honey or maple syrup You can substitute a whole "powdered" sugar, such as Sucanat, maple sugar, coconut sugar, or date sugar.


  • When it comes to fermenting cranberries, to ferment them properly and use them to make cranberry sauce, you will want to split the cranberries. You can do this by chopping them with a knife or smashing them in a jar or a large bowl using a kraut pounder, wooden spoon, or spatula.
  • When you are splitting the cranberries, you may be tempted to chop them in a blender. DO NOT do this. They will be chopped too finely and will ferment too quickly, creating alcohol. You may use a food processor, but if you do this, you will need to be very careful. You will need no more than a few pulses to sufficiently chop the cranberries.
  • Once the cranberries are split, add them to the jar, if they are not already in the jar.
  • Add the salt and the whey to the jar.
  • Add the water to the jar until the cranberries are completely submerged.
  • Weigh down the cranberries in the jar with a second small jar or a glass fermentation weight.
  • Put the cap on to the jar and place the jar in an undisturbed place out of direct sunlight where the temperature is approximately between 68°F and 72°F. (As a safeguard, I HIGHLY recommend placing the jar into a bowl to catch any fermentation brine that might bubble out of the jar, even with the lid on. See my video for an example.)
  • Each day, release the cap on the jar to remove any buildup of carbon dioxide. If you use special equipment, such as a "pickle pipe" or another fermentation device, you do not need to do this step.
  • After a few days, you should start to notice a few bubbles accumulating in your jar. The bubbles indicate the fermentation process is moving in the right direction. The secret is to "catch" your fermentation when it is in the bubbling stage before it moves on to turn into alcohol. (This stage of fermentation usually occurs within 3-4 days. See below.)
  • Within 3-4 days, you should see a lot of bubbles, and this indicates that your fermented cranberries are ready. Now is time to move on to the next step.
  • Using a mesh strainer, strain your cranberries over a bowl to catch the cranberry brine. DO NOT throw this brine out.
  • Transfer the cranberries to a bowl and add a whole sweetener to your taste. I recommend between 1/4 cup to 1/3 cup honey. (In my recipe video, I like to use 1/4 cup for myself or 1/3 cup if I'm making the cranberry sauce for my family.)
    If you would prefer to use a whole sweetener, such as Sucanat, I recommend that you pulverize it first to make it into a powdered form. It will then blend much easier with the fermented cranberries. If you are using a powdered sugar, you may need up to 1/2 cup to reach the desired sweetness. If the cranberries appear dry, you can add back some of the brine.
  • Decant the fermented cranberry sauce into a jar and refrigerate. It will stay fresh, refrigerated, for about 2-3 weeks, after which time it will begin to turn into alcohol and then vinegar.
  • You will want to save the remaining brine and use it as a jumpstart for other fruit ferments. You can add the brine to the other ferments in addition to whey and salt.
    As an alternative, you can use this brine to make a refreshing probiotic-rich beverage. Add 1/4 cup of the brine to a tall glass, stir in a bit of honey or honey simple syrup, and then top off your beverage with some sparkling water for a refreshing "Mocktail." (See the recipe notes for information on how to make a honey simple syrup.)



Keep in mind that fruit ferments VERY quickly. Even after the fermented cranberry sauce is refrigerated, it will continue to ferment, just at a much slower rate than it would at room temperature.  However, even at this slowed fermentation rate, fermented cranberry sauce (or any fermented fruit) will begin to turn into alcohol and then eventually into vinegar.  So be sure to consume all your fermented fruit within the first few weeks of making it.
