Fermented garlic is one of the easiest ferments you can keep on your shelf. It lasts a long time, tastes stronger than raw garlic, and brings that deep, old world flavor into every dish. People used to keep a jar of this around as naturally as they kept salt. If you want a dependable ferment that almost never fails, start here.
What Fermented Garlic Is
It is fresh garlic submerged in salt water and left to ferment through natural lactic acid bacteria. The brine protects the cloves from spoilage while the microbes do what they have always done. The result is a softer clove, a mellow sharpness, and a juice that adds punch to anything you cook.
Why Garlic Ferments So Well
Garlic is loaded with natural sugars. Once you place the cloves under a proper salt brine, the bacteria have everything they need. They break those sugars down, create lactic acid, and preserve the garlic for months. It is one of the safest ferments as long as you use enough salt and keep everything under the brine.
Safety Notes
Use a two to three percent salt brine. Keep every clove under the liquid. If anything pokes up above the brine, it will spoil. If you see white film on top, that is usually harmless yeast and can be skimmed. If you smell anything rotten or see fuzzy colors, toss it.
Fermented Garlic Recipe
Ingredients
- Garlic cloves
- Salt
- Water (non chlorinated)
Steps
- Peel the garlic cloves.
- Mix a brine of two to three percent salt. That is two to three grams of salt per one hundred grams of water.
- Pack the cloves into a clean jar.
- Pour the brine over them until they are fully covered.
- Add a weight if the cloves want to float.
- Close the lid loosely or use an airlock lid.
- Let it ferment at room temperature for one to three weeks. Taste until you like it.
- Move it to the refrigerator when ready.
How to Use It
Use the cloves anywhere you would use garlic. They are sharper in aroma but mild in bite. The brine is liquid gold. Add it to soups, dressings, marinades, scrambled eggs, and anything that needs a quiet kick. Once you start using the brine, you will not stop.
Troubleshooting
-
Can fermented garlic go bad?
Yes. If you see fuzzy mold or smell anything rotten, throw it out. A thin white film is usually harmless yeast and can be skimmed.
-
Does fermented garlic need to be refrigerated?
Eventually. Once it tastes how you like it, store it in the refrigerator to slow the ferment. It will keep for months.
-
How salty should the brine be?
Two to three percent salt by weight. This is the old standard and keeps the ferment safe.
-
Why is my garlic turning blue or green?
Garlic can react with sulfur compounds during fermentation. The color shift is harmless and actually shows the chemistry is active.
-
Do I need an airlock lid?
No. A loose lid works fine. People fermented garlic long before modern lids existed. Just keep the cloves under the brine.
-
How long does fermented garlic last?
If the brine covers every clove and the jar stays cold, it can last many months. Some people keep jars for a year without trouble.
-
Can I use tap water?
If it has chlorine, boil it first or let it sit out overnight. Chlorine can slow or weaken the ferment.
-
Can I use table salt?
Avoid iodized salt. It can cloud the brine and affect flavor. Use sea salt, pickling salt, or kosher salt.
