In recent years, pickled sauerkraut has made a major comeback — not just as a tangy condiment for your hot dog, but as a superfood packed with probiotics, fiber, and vitamins. Whether you’re interested in gut health, traditional food preservation, or just love bold, tangy flavors, sauerkraut deserves a place in your kitchen.
In this ultimate guide, you’ll learn what sauerkraut is, how to make pickled sauerkraut at home, its top health benefits, how it compares to kimchi, and how long sauerkraut lasts when stored properly.
What Is Pickled Sauerkraut?
Sauerkraut is finely shredded fermented cabbage, traditionally made by packing cabbage with salt and letting it ferment naturally over several days or weeks. While often referred to as “pickled,” true sauerkraut is fermented, not pickled with vinegar. This process creates beneficial probiotics that improve digestion and boost immune function.
However, store-bought sauerkraut is sometimes pickled with vinegar and pasteurized, which kills the live cultures. If you’re looking for the health benefits of fermented sauerkraut, opt for raw, unpasteurized versions.
Sauerkraut Benefits for Health
Searches for “sauerkraut benefits” have skyrocketed in recent years, and for good reason. Here’s why this humble food is considered a nutritional powerhouse:
1. Improves Gut Health
Sauerkraut is rich in probiotics, which help maintain a healthy balance of gut bacteria. This can improve digestion, reduce bloating, and support nutrient absorption.
2. Boosts Immunity
Your gut is closely tied to your immune system. The live cultures in sauerkraut enhance immune response and help fight infections.
3. Supports Weight Loss
Low in calories and high in fiber, sauerkraut helps you feel full longer — which can support a healthy weight.
4. Rich in Nutrients
A serving of sauerkraut delivers vitamin C, vitamin K, iron, potassium, and antioxidants that combat inflammation.
5. May Improve Mental Health
Emerging research links gut health to mental well-being. Probiotics may help reduce symptoms of anxiety and depression.
How to Make Pickled Sauerkraut at Home (Step-by-Step)
If you’ve searched how to make sauerkraut at home, you’re not alone. It’s simple, requires just 2 ingredients, and no fancy equipment.
Ingredients:
- 1 medium head of green cabbage
- 1 tablespoon of sea salt (non-iodized)
Optional: Caraway seeds, garlic, ginger, shredded carrots, beets, or turmeric for flavor.
Instructions:
1. Shred the Cabbage
Remove outer leaves, cut the cabbage in half, remove the core, and shred finely using a knife or mandoline.
2. Massage with Salt
Place shredded cabbage in a large bowl. Sprinkle salt over it and massage thoroughly with your hands for 5–10 minutes. The cabbage will release water and soften.
3. Pack into Jar
Pack the salty cabbage into a clean, wide-mouth glass jar. Press it down firmly so the liquid rises above the cabbage. This is your brine.
4. Weigh It Down
Use a fermentation weight, small jar, or a clean rock to keep the cabbage submerged under the brine.
5. Cover and Ferment
Cover with a cloth or loosely fitted lid. Leave it at room temperature (around 65–72°F) away from direct sunlight for 5–10 days. Taste daily after day 5.
6. Refrigerate
Once it reaches your desired tanginess, seal and refrigerate. This slows fermentation and preserves freshness.
How Long Does Sauerkraut Last?
One of the top search queries is: How long does sauerkraut last?
- Refrigerated, unpasteurized sauerkraut: Up to 6 months if kept submerged in brine.
- Pasteurized store-bought versions: Check the expiration date; once opened, consume within 1–2 months.
Tip: Always use a clean fork when serving to avoid introducing bacteria.
Sauerkraut vs Kimchi: What’s the Difference?
Both are fermented cabbage dishes, but they have key differences:
| Feature | Sauerkraut | Kimchi |
|---|---|---|
| Origin | Central/Eastern Europe | Korea |
| Flavor | Sour, mildly salty | Spicy, tangy, umami-rich |
| Ingredients | Cabbage + salt | Cabbage + garlic, chili, ginger |
| Probiotic content | High | High |
| Texture | Soft, tender | Crisp, bold |
If you love fermented foods, try both! But for those who prefer a milder, non-spicy option, sauerkraut is the go-to.

Pickled Sauerkraut vs Vinegar-Pickled Cabbage
While the term “pickled sauerkraut” is common, it’s important to note:

If you want the gut-health perks, go for fermented sauerkraut, not vinegar-pickled.
