What is Traditional Sauerkraut Made From?
At its core, traditional sauerkraut is a very simple food. The word is German for "sour cabbage," and the process reflects this simplicity. It involves a natural fermentation process where thinly shredded cabbage is mixed with salt and left to ferment over a period of weeks. The salt pulls moisture out of the cabbage to create a brine, and naturally occurring lactic acid bacteria then convert the sugars into lactic acid. It's the lactic acid that gives sauerkraut its characteristic sour flavor and acts as a preservative. This two-ingredient base—cabbage and salt—is completely plant-based, making traditional sauerkraut suitable for both vegetarian and vegan diets.
Potential Non-Vegetarian Additives
While the base recipe is safe for vegetarians, not all store-bought sauerkraut products are created equal. Consumers must be vigilant and check ingredient lists, particularly for cooked or flavored varieties.
- Flavoring agents: Some processed brands, particularly those marketed for specific dishes like a German-style hot dog topping, might include flavorings derived from meat products, such as bacon or beef broth.
- Stabilizers or thickeners: While less common, certain additives could be animal-derived. Reading the full ingredients list is the only way to be certain.
- Cooking methods: Some restaurants and recipes will cook sauerkraut with non-vegetarian items like sausage, pork, or lard. If ordering out, it's important to ask about the preparation process to ensure it's suitable for a vegetarian diet.
The Difference Between Fermented and Pickled Cabbage
It's important to understand the difference between true fermented sauerkraut and vinegary pickled cabbage. While both have a tangy taste, only one offers the probiotic benefits and adheres to the traditional, vegetarian method.
- Fermented Sauerkraut: Relies on a natural, anaerobic process where lactic acid bacteria produce the sour taste. These products are typically found in the refrigerated section of the grocery store to preserve the live cultures. Ingredients are typically only cabbage and salt.
- Pickled Cabbage: Is a quick-cooked product that uses vinegar to achieve the sour flavor, rather than natural fermentation. It is often sold in cans or shelf-stable jars and contains no live probiotic cultures. Ingredients may include water, vinegar, and preservatives.
A Simple Comparison Table
| Feature | Fermented Sauerkraut (Raw) | Pickled Cabbage (Pasteurized) |
|---|---|---|
| Key Ingredients | Cabbage, Salt | Cabbage, Water, Vinegar, Salt, Spices |
| Preparation | Natural anaerobic fermentation | Cooked and brined in vinegar |
| Probiotic Content | Rich in live, beneficial bacteria | Contains no live probiotic cultures |
| Flavor | Complex, tangy, and naturally sour | Sharp, vinegary flavor |
| Health Benefits | Supports gut health, immunity | No probiotic benefits, mainly for flavor |
| Storage | Refrigerated | Shelf-stable until opened |
| Vegetarian Status | Generally safe (check for additions) | Safe (generally) |
How to Ensure Your Sauerkraut is Vegetarian or Vegan
For those following a strict vegetarian or vegan diet, here are a few tips to make sure your sauerkraut is free of any animal products:
- Look for labels indicating "vegan" or "raw": Many brands now clearly label their products, especially those focusing on health benefits and raw fermentation. Look for brands like Kühne or Olive My Pickle, which offer vegan options.
- Shop the refrigerated section: Unpasteurized, live sauerkraut is usually found in the refrigerated section. Cans and shelf-stable jars are almost always pasteurized and less likely to contain live probiotics, though some may still be vegetarian.
- Check the ingredients list: The most reliable method is to read the label. For a vegetarian and vegan product, the ingredients should only be cabbage, salt, and any plant-based seasonings like caraway seeds or juniper berries.
- Make it yourself: The simplest and most foolproof way to ensure a vegetarian product is to make your own. With just cabbage and salt, you control every step of the process.
Conclusion: A Fermented Favorite for Plant-Based Diets
In conclusion, traditional sauerkraut is indeed vegetarian and vegan, as it's made from just cabbage and salt through a natural fermentation process. However, to guarantee it fits your dietary needs, vigilance is key. Always check the ingredient list on store-bought varieties to avoid unexpected additives like animal-derived flavorings. Opt for raw, refrigerated sauerkraut for the purest, probiotic-rich experience. This allows plant-based eaters to confidently enjoy the tangy, crunchy goodness of this traditional condiment and reap its potential digestive health benefits.

A Simple Sauerkraut Recipe
Making your own sauerkraut is a rewarding and easy process. Follow these basic steps for a foolproof batch.
- Gather Ingredients: Start with one medium head of green cabbage (about 3 pounds) and 1.5 tablespoons of kosher or canning salt. Optional additions include caraway seeds or other whole spices.
- Prepare the Cabbage: Discard the outer leaves and core the cabbage. Shred it finely using a mandoline or a sharp knife.
- Salt and Massage: Place the shredded cabbage in a large bowl, sprinkle with salt, and massage with your hands for 5-10 minutes. The cabbage will start to soften and release liquid.
- Pack and Ferment: Tightly pack the cabbage into a clean mason jar, pressing down firmly so the liquid rises above the cabbage. Place a weight on top to keep the cabbage submerged. Cover with a cloth and ferment for 3 to 10 days at a cool room temperature, tasting as you go. Refrigerate when it reaches your desired tanginess.
This simple process gives you complete control over your ingredients, ensuring your sauerkraut is 100% vegetarian and vegan.
