Do you discard the juice left after enjoying sauerkraut? If so, you’re missing out on a nutrient-dense, flavorful liquid packed with probiotics and vitamins. Sauerkraut juice is versatile, tasty, and easy to add to your routine. Before exploring ways to use it, here’s a quick note on choosing and making high-quality sauerkraut.
Properly fermented sauerkraut delivers vitamins, fiber, and diverse probiotic strains that support digestion and immunity. Many people notice improvements in digestion and overall wellness when they include fermented foods regularly. If you’re sensitive to sugars or yeast, sauerkraut can be a better option than sweetened ferments like some kombuchas or certain yogurts.
I prefer making sauerkraut at home because it’s inexpensive and typically contains more active cultures than most store-bought versions. If you buy sauerkraut, pick refrigerated products labeled “fermented” or “live cultures” and check that the ingredients are simple—usually cabbage, salt, and water, without added sugar or vinegar. Refrigerated, unpasteurized brands will retain the beneficial bacteria.
If you end up with extra sauerkraut brine, save it. Here are nine practical and enjoyable ways to use sauerkraut juice.
1. Drink it straight as a gut shot
Sauerkraut juice can be consumed like commercial “gut shots.” If you enjoy the sour, tangy taste, a small daily shot delivers a concentrated dose of probiotics. Many people take one in the morning or before bed as a food-based probiotic alternative to pills. Probiotics from real fermented foods are often better absorbed and more affordable than supplements.
2. Use it in salad dressing and other sauces
Sauerkraut juice makes a great acidic component for dressings and sauces. Replace lemon juice or vinegar with an equal amount of sauerkraut juice to add bright flavor and probiotics to vinaigrettes, marinades, and creamy dressings.
3. Splash over cooked vegetables and meat
A dash of sauerkraut juice can instantly lift the flavor of cooked vegetables, roasted meats, or grains. Acidity brightens dishes and balances richness, and sauerkraut juice offers that tang plus beneficial microbes.
4. Start your next batch of sauerkraut or pickles
Reserve some brine as a starter when you make a new batch of sauerkraut or quick pickles. A small amount of active sauerkraut juice helps jump-start fermentation and can speed up the process while improving reliability in homemade ferments.
5. Add it to dips
Sauerkraut juice works well in savory dips, adding a tangy, salty note that complements creamy bases. Swap it for apple cider vinegar or lemon juice in recipes like onion bacon dip, hummus variations, or savory spreads for a probiotic boost and bright flavor.
6. Give it to your pet
Pets can benefit from the enzymes and probiotics in sauerkraut juice, especially if they’ve had antibiotics or eat processed kibble. Start with a small amount—about a teaspoon over food for medium dogs, less for small pets—and increase as tolerated. Many pets adapt quickly and enjoy the added flavor and digestive support.
7. Use it as a pickleback or in cocktails
Sauerkraut juice can be used as a chaser for shots (a pickleback) or as an ingredient in savory cocktails like Bloody Marys or Micheladas. While cocktails aren’t a health strategy, using probiotic-rich brine is a tastier, more nourishing option than plain brine or vinegar.
8. Marinate meat with it
The acidity in sauerkraut juice helps tenderize meat by breaking down proteins, so it’s a good base for marinades, especially with pork. Note that heat can reduce probiotic benefits, so marinating enhances flavor and tenderness more than preserving live cultures.
9. Use it as a facial toner
Because sauerkraut juice is mildly acidic and contains vitamins and enzymes, some people use a diluted mix as a skin toner to help restore skin pH and gently exfoliate. Start with one part sauerkraut juice to four parts water and patch-test on sensitive skin. If tolerated, you can adjust the ratio and store the mixture refrigerated.
There are many practical ways to use leftover sauerkraut juice—drink it, cook with it, feed it to pets, or even use it on skin. Next time you have brine left over, try one of these ideas and enjoy its flavor and benefits instead of throwing it away.
