Fermented Honey: How to Ferment Raw Honey (Garlic, Fruit & More)

Fermenting honey sounds like something that should go wrong. But when it works, it creates one of the most complex, flavorful ingredients you can make at home.

I still remember the first jar I made: garlic slowly sinking, bubbles forming after day three, and that first taste – sweet, sharp, almost alive.

In this guide, I’ll show you exactly how honey fermentation works (and why it sometimes fails), plus the best ingredient combinations, safety tips, and real examples from my own batches.

What is fermented honey (quick answer)?

Fermented honey is raw honey that has absorbed moisture (from garlic, fruit, or water), activating natural yeasts and bacteria and starting a gentle fermentation process.

• Used for culinary recipes, wellness, and natural remedies
• Made with raw or really raw honey, not pasteurized
• Uses natural yeasts and bacteria already present in the honey
• Creates bubbles, a slightly tangy flavor, and a thinner syrup
• Usually not alcoholic (unless too much water turns it into mead)
• Commonly made as fermented honey garlic (garlic honey) or with fruit

Fermented honey is becoming increasingly popular among chefs looking for new ways to add flavor to their dishes. While it seems like a new trend, it has been used as a sweetener for thousands of years. It is one of the healthiest sweeteners available, with a unique taste in sauces, marinades, or even as a condiment for cheese plates. It also makes an excellent ingredient for this honey carrot soup.

How Honey Fermentation Actually Works – Simple Science Explained

The magic of fermented honey comes from its simple ingredients. Raw, unpasteurized honey contains naturally occurring enzymes and yeast. When its moisture content reaches 19-20%, fermentation begins, just like making mead.

Although the natural amount of water in honey is around 16-17%, its sugars draw out moisture from ingredients like fruits or veggies, helping reach the 20% needed for fermentation. If you are fermenting dried fruits or dates and figs, you can add a little extra water. 

Moisture and warmth are two factors that help to kick-start the process of forming bubbles and transforming honey into a frothy concoction that can sometimes overflow the jar. Unlike other fermented items like wine and beer, honey does not automatically become alcoholic. However, if the moisture content is greater, it turns into mead.

Should You Add Water or Not?

IF using fresh fruit → No water needed (fruit releases moisture)

Using dried fruit → Add 1–2 tbsp water

IF using garlic → No water, but shake daily

Honey is thick + no bubbles after 5 days → Add 1 tsp water or ACV

Honey Fermentation vs. Lacto-Fermentation: What’s the Difference?

Lacto-fermentation uses lactic acid bacteria to convert sugars into lactic acid. This is the process behind foods like yogurt, sauerkraut, sourdough, and kimchi.

Fermented honey works differently. It relies on natural yeasts and bacteria present in raw honey. When you add moisture, these microorganisms begin the fermentation process, creating bubbles and a mild tangy flavor.

Unlike lacto-fermented foods, fermented honey does not produce lactic acid and is usually less sour. Instead, it develops a sweeter, more complex flavor – especially in recipes like fermented honey garlic.

Ingredients

Raw honey

To successfully ferment honey, you have to use raw honey, not pasteurized. It is quite challenging nowadays to find it as most of the store-bought honey is heat treated to kill off wild yeast and unwanted bacteria. I use local honey from our beekeeper neighbor.

In addition, raw honey contains pollen, which can help allergy sufferers build up a tolerance over time.

Fruits or veggies (optional)

Honey will ferment on its own if it has a high enough moisture content (around 19-20%). When you add water in warm temperatures, the natural yeast and enzymes in honey start to consume sugars in the honey and kickstart the process.

However, adding fruits or vegetables enhances flavor, adds moisture, and makes the process more fun.

You can choose from cranberries, elderberries, ginger, lemon, or garlic, it’s up to you! Even fruits like apples or quince will work. Just be sure to select fresh produce, as it plays a key role in fermentation. I would also opt for organic produce, as it is less likely to have been treated with chemicals that might reduce its natural yeast content essential for fermentation.

What Most People Get Wrong When Fermenting Honey

Fermenting honey sounds simple – and it is. However, a few small mistakes can completely change the outcome. I’ve made most of them myself, and they’re easy to avoid once you know what to look for.

Using the wrong honey (why nothing happens)

This is the most common reason fermentation fails completely.

If your honey has been pasteurized or ultra-filtered, it may look perfect, but it’s essentially “inactive.” You can wait days or even weeks and still see no bubbles at all.

If that happens, it’s not your method—it’s the honey.

Not enough moisture

Honey on its own is too dry to ferment (usually around 16–17% water). Fermentation only starts when moisture reaches around 19–20%.

If you’re using ingredients that don’t release much liquid (like dried fruit), fermentation may never begin unless you add a small amount of water.

Filling the jar too much

This is one of the easiest mistakes – and the messiest.

As fermentation starts, bubbles form and the honey expands. If your jar is too full, it can overflow quickly. Leave some space at the top and place the jar on a plate just in case.

Not submerging the ingredients

Anything exposed to air can develop mold.

Fruits and vegetables tend to float, especially at the beginning. If they’re not fully coated in honey, you increase the risk of spoilage. That’s why flipping or shaking the jar daily matters.

Forgetting to burp the jar

During the first couple of weeks, fermentation produces gas.

If you don’t release that pressure regularly, the lid can build up pressure (or even leak). A quick daily “burp” is enough.

Expecting instant results

Fermentation takes time.

You might not see bubbles for a few days, especially in cooler environments. That doesn’t mean it’s not working. Some of my best batches took a full week before showing any signs of activity.

Troubleshooting: Why Your Honey Didn’t Ferment

No bubbles after 1 week
→ Honey may be too dry or not truly raw. Try adding 1 teaspoon of water or using really raw hon

Mold on top
→ Ingredients were not fully submerged. Discard the batch and start fresh

Alcohol smell
→ Too much water added. The ferment is turning into mead (still usable, but different).

Overflow mess
→ Jar was too full. Always leave headspace for bubbling.

How to make honey fermented fruits or veggies

First step – prepare your chosen fruits (or vegetable).

Use soapy water or a dishwasher to sterilize the jars before filling them with your chosen fruits or veggies so it is 3/4 full. 

Wash them and slice them thinly before adding them to the jar

Second step – fill the jar with honey.

Pour the honey over the ingredients so they are fully submerged in the honey. Use a wooden spoon to move them around so the ingredients are fully coated and the honey can reach the bottom of the jar. You can also drizzle some honey at the bottom of the jar.

Bare in mind that once bubbles start to form in the honey, it turns into a frothy concoction, and honey can spill over the jar. Therefore, don’t fill a jar to the top; give the honey a breathing space. I put a plate underneath my honey mixture so that the liquid can leak out.

Third step – allow the fermentation process to begin.

Cover with a lid and place in a cool, dark spot at room temperature. Since the fruits naturally float to the top of the honey, shake the jar daily to ensure they are coated in honey.

You will need to burp daily during the first two weeks of fermentation. First, loosen the lid on the jar so the gases can escape. Flip the jar upside down once a day. Before flipping, ensure you’ve fastened the lid tightly. Once you flip it back, loosen it once more for gasses to escape while fermenting. After a few days, you will see the first signs of fermentation. Bubbles will appear on top of the honey, and burping will gradually slow down. After the first few weeks, you will notice the produce sinks below the honey (and is noticeably darker), and the need to stir or turn the jar is essentially over.

Note: Some people speed up the fermentation process by adding a teaspoon of organic apple cider vinegar.

After several weeks to a month, you can enjoy honey fermented food. However, it tastes even better after a month!

Fourth step – Store the ferment.

Once the honey has achieved its desired level of fermentation, store it securely in an airtight jar, as oxygen exposure can damage the fruits. Place the jar in a dark and cool place with no direct sunlight.

Over time, honey has thinned and the fermentation process makes the honey darker, with some reduction in size among the fruits or veggies. Nevertheless, honey ferment preserves its delightful taste and is packed with probiotics.

Eating fermented honey may boost the immune system, improve digestion or lower your cholesterol.

Is Fermented Honey Safe?

• Always keep ingredients fully submerged
• Use clean jars to prevent contamination
• Avoid giving fermented honey to infants (risk of botulism)
• If you see mold or smell something unpleasant, discard immediately

Fermented Honey Checklist

Stage	What to Do	Why It Matters
Before you start	Use raw, unpasteurized honey	Needed for natural yeasts and proper fermentation
	Sterilize the jar	Prevents unwanted bacteria or mold
	Choose fresh or properly dried ingredients	Ensures good flavor and safe fermentation
During fermentation	Burp daily (first 2 weeks)	Releases gas and prevents pressure buildup
	Shake or flip the jar	Keeps ingredients coated in honey
	Keep ingredients submerged	Prevents mold from forming
After fermentation	Taste before storing	Check flavor and fermentation level
	Store in a cool, dark place	Slows fermentation and preserves quality
	Strain (optional) for long-term storage	Improves shelf stability

Long-Term storage

For more shelf-stable jar of honey and to reduce the risk of mold and fermentation issues, strain the veggies or fruits from the honey after 3-4 weeks.

What To Do With Fermented Honey?

With its taste and ideal consistency, fermented honey can be used in many ways. It is best to stay away from heating the honey, though, as high temperatures can destroy many of the beneficial bacteria.

in cooking

Use it wherever you use honey, like a condiment, marinade or this honey mustard dressing. It is also great in vinaigrette or glaze for meats, cheese or seafood. Spread it on sandwiches or toast. Honey can also be used as a natural sugar alternative in the form of Honey syrup. I love to use it as a sweetener in lemonades, cocktails, smoothies, or jams or eat it with natural yogurt, muesli or grilled pears.

as natural remedy

Fermented honey has traditionally been used as a natural remedy for sore throat, colds, and flu season. This natural remedy possesses anti-inflammatory and antimicrobial properties that help to boost your immune system.

While fermented honey isn’t as rich in probiotics as sauerkraut or yogurt, it still contributes beneficial compounds that may support gut health and digestion.

I enjoy spoonfuls of this honey or preparing honey cough drops or sore throat sprays.

Beauty.

You can use honey ferment in facial masks for acne and other skin conditions; add it to soap bars or creams.

Get Creative with Honey Ferments

I’ve tested several of these, and garlic ferments the fastest (you’ll see bubbles within 2–3 days), while cranberries take longer but develop a deeper, almost wine-like flavor.

To create unique taste combinations, you can use honey to ferment fruits, vegetables, and grains. Some popular honey ferments include:

Fermented Honey Garlic

a potent, slightly spicy syrup with deep savory notes, traditionally used for immune support and cold season remedies.

Cranberries + honey

bright, tart, and slightly effervescent, perfect for cheese boards or adding a festive touch to winter dishes.

Ginger + lemon + honey

warm, zesty, and gently spicy, often used as a soothing blend for digestion and sore throats.

Apples + cinnamon + honey

soft, naturally sweet with a hint of spice, creating a dessert-like ferment that pairs beautifully with yogurt or porridge.

Get More Creative with:

Honey Kombucha.

It is a fermented tea made by adding honey to tea and a kombucha culture to the mixture. The result is a sweet, fizzy, and slightly sour drink.

Honey Mead.

This ancient alcoholic drink ferments honey, water, and yeast. Since the moisture content is higher, honey turns into mead, also known as honey-wine. The result is a sweet, fruity drink that one one can flavor with spices or fruits.

Honey-Fermented Fruits.

You can ferment fruits like cranberries, grapes, and apricots with honey to create a sweet and tangy condiment and use it on cheese plates, in salads, or as a topping for ice cream.

Honey-Fermented Vegetables.

You can use honey to ferment vegetables like garlic cloves, carrots, cucumbers, and beets to create a sweet and sour pickled vegetable.

Honey-Fermented Grains.

You can use honey to ferment grains like oats, barley, and wheat to create a sweet and tangy cereal or granola and eat it for breakfast or as a snack.

FAQ

Is fermented honey safe?
Yes, if you submerge all ingredients, then no mold forms.

Can fermented honey go bad?
Rarely, but mold or foul smell = discard.

Does fermented honey contain alcohol?
Natural yeasts in fermented honey produce small amounts of alcohol as they break down sugars, but the amount is usually minimal. Adding too much water can turn it into mead and make it noticeably alcoholic.

How long does it last?
Months to years if stored properly.
