Place the peeled garlic cloves in a quart mason jar, leaving 2-3 inches of space at the top and pour the sauerkraut juice over the garlic.
5 large garlic bulbs, 2 tablespoons sauerkraut juice
In another jar, dissolve the salt in 1/3 cup of hot water. Once the salt has dissolved, add the rest of the water cold to the jar to cool it down.
⅓ cups of water, 4 teaspoons salt, 2 ⅔ cups of water
Pour the saltwater into the jar with the garlic, covering all of the garlic and leaving about an inch of space at the top.
Place a fermentation weight on top of the garlic and screw on the lid.
Put the jar in a dark location between 65 and 70 degrees. Burp the jar once a day to release pressure caused by fermentation.
Ferment the garlic for 3-8 weeks, depending on your taste preference. The longer it ferments, the milder the flavor will become.
Once it's done fermenting, store in the fridge.
