🤔 What Is Canned Sauerkraut?
Canned sauerkraut is finely shredded cabbage that has been fermented by lactic acid bacteria and then heat-processed and sealed in a can to make it shelf-stable. It has a distinctively sour and tangy flavor with a soft, crisp texture, serving as a popular condiment for hot dogs and sausages or as a side dish for rich meats like pork.

The Triple-S Method
Master the three essential steps for food success:
🛒 SHOP SMART: Selection Guide
- Check the can or jar: Ensure the seal is intact, with no dents, bulges, or rust.
- Read the ingredients: Traditional sauerkraut contains only cabbage and salt. Some varieties add caraway seeds, dill, or wine.
- Note the processing: Canned sauerkraut is pasteurized; for live probiotics, you must buy refrigerated, unpasteurized versions.
Appearance
Sauerkraut should have a pale, translucent, yellowish-white color. It should be moist and crisp-looking, not brown, dry, or mushy.
Smell
It should have a clean, tangy, and acidic aroma. A musty, yeasty, or foul smell is a sign of spoilage.
Texture
Good sauerkraut has a pleasant, crunchy texture. If it is soft, slimy, or mushy, the quality is poor.
Common Varieties / Types
Variations in sauerkraut typically come from added flavorings.
- Traditional/Plain: Made simply with cabbage and salt, offering a pure, tangy flavor.
- Bavarian Style: Often slightly sweeter, and may include caraway seeds, juniper berries, and sometimes sugar or apple.
- With Wine: Some European styles add a splash of dry white wine (like Riesling) during fermentation for a more complex flavor.
📅 Seasonal Buying Guide
North America (USA/Canada)
Canned sauerkraut is available year-round with no seasonal price changes. The cabbage used is typically harvested in the fall and processed for year-long supply.
Europe
As a staple in many Central and Eastern European countries, sauerkraut is consistently available year-round in cans, jars, and fresh forms.
Australia/New Zealand
Canned sauerkraut is a standard item in most supermarkets, available consistently throughout the year.
Tropical/Subtropical Regions
Availability is generally limited to larger supermarkets that stock imported international foods, but it can be found year-round.
❄ STORE FRESH: Storage Guide
- Unopened: Pantry for 2-3 years.
- Opened: Refrigerator for 5-7 days.
- Ideal Temperature: Cool, dark pantry below 29°C (85°F); refrigerator at 0-4°C (32-39°F).
Storage Method Details
Pantry: Store unopened cans or jars of sauerkraut in a cool, dark place. This preserves its crisp texture and prevents the flavor from degrading over time.
Refrigerator: Once opened, transfer the sauerkraut to an airtight, non-metallic container, ensuring the cabbage remains submerged in its brine. Its high acidity acts as a natural preservative, keeping it safe for about a week in the refrigerator.
Pest Prevention
A clean pantry is the best defense against pests. For opened sauerkraut, a tightly sealed container is important to prevent contamination and keep its strong aroma from affecting other foods.
Sauerkraut is a high-acid food due to the lactic acid created during fermentation. This acidity creates an inhospitable environment for most spoilage bacteria, which is why it has a long shelf life, both unopened and for a period after opening when refrigerated.
⚠ STAY SAFE: Food Safety Tips
- Max Time at Room Temp: 2 Hours (once opened)
Understanding Food Safety Rules
Always inspect the can or jar for a proper seal before use. After opening, sauerkraut should be refrigerated within two hours. While its acidity provides protection, it is not immune to spoilage, especially from molds and yeasts, when left in the “Temperature Danger Zone” (4°C-60°C / 40°F-140°F).
Reheating Methods
Sauerkraut can be eaten cold but is often heated when served as a side dish.
Microwave
Place in a microwave-safe bowl and heat for 1-2 minutes until warm.
Air Fryer
For a crispy texture, squeeze out excess moisture, toss with a little oil, and air fry at 190°C (375°F) for 10-15 minutes until browned.
Oven/Toaster Oven
Incorporate into a baked dish like a casserole with sausage and potatoes.
Stovetop
The best method. Gently simmer the sauerkraut with its juice (or drained, with a little broth or beer) in a saucepan for 10-15 minutes to mellow its flavor and heat it through.
Date Labels Explained
The “Best By” date on canned sauerkraut is a quality guideline. Due to its high acidity, it remains safe to eat long after this date if the seal is intact, though it may lose some of its crispness over time.
Allergen Information
- Contains: None of the top 9 allergens.
- Special Considerations: High in histamines and tyramine.
Allergen Handling & Prevention
As a fermented food, sauerkraut is naturally high in histamines and tyramine. Individuals with histamine intolerance or those taking MAOI antidepressants should consume it with caution as it may trigger adverse reactions.
⚠ Special Safety Considerations
The primary health consideration for canned sauerkraut is its very high sodium content from the salt used in curing. Individuals on a low-sodium diet should rinse the sauerkraut thoroughly before use to wash away excess salt.
🧊 Freezing & Thawing Guide
Freezing Effects & Preparation
Freezing canned sauerkraut is not recommended. The freezing process will destroy its characteristic crisp texture, making it very soft and mushy upon thawing.
While the flavor will be preserved, the significant loss of textural quality makes it unsuitable for most traditional uses. It is best to purchase a container size that can be used within a week.
Recommended Thawing Methods
As freezing is not advised, there are no ideal thawing methods for this product.
Not Recommended
Freezing and thawing canned sauerkraut should be avoided to preserve its essential crisp texture.

🌎 Sustainability & Sourcing
Sauerkraut is a highly sustainable food. It is made from cabbage, a hardy and high-yield crop, and the fermentation and canning processes are ancient methods of preservation that drastically reduce food waste.
Making sauerkraut is also an excellent way to preserve a local cabbage harvest at home, further reducing food miles and packaging.
🔄 Substitutions & Alternatives
For a similar tangy crunch on a sandwich, pickled cabbage (coleslaw) or another pickled vegetable like kimchi can be used. Kimchi, however, will also add significant spice.
If a recipe calls for sauerkraut as a cooking ingredient, you can sometimes substitute fresh shredded cabbage cooked with a splash of vinegar to mimic the flavor.
🔪 Recommended Tools
A can or jar opener is all that is needed. An airtight glass jar is the best choice for storing leftovers to prevent the acidic kraut from reacting with plastic and to contain its odor.
💡 Pro Tips
♻ Waste Reduction
The brine from sauerkraut is tangy and flavorful. Do not discard it; use a splash to add acidity to salad dressings, marinades, or to deglaze a pan after cooking pork chops.
❓ FAQ
A: No. The high-heat canning process (pasteurization) kills the beneficial live bacteria that are created during fermentation. Only fresh, refrigerated sauerkraut is a source of probiotics.
A: Salt is a crucial ingredient in making sauerkraut. It draws water out of the cabbage to create the brine and inhibits the growth of bad bacteria while allowing the beneficial lactic acid bacteria to thrive.
A: Yes, rinsing sauerkraut under cool water is a very effective way to reduce its sodium content and mellow its sour flavor if you find it too intense.
A: When refrigerated in a sealed container and kept submerged in its brine, it can last for 5-7 days.
A: It is not recommended. Freezing destroys the cell walls of the cabbage, which will result in a very mushy and unappealing texture once thawed.
A: No. Pickling typically involves preserving in an acidic liquid like vinegar. Sauerkraut is fermented, meaning its sour taste comes from lactic acid produced by bacteria converting sugars in the cabbage.
A: The best way is to simmer it slowly. This mellows its sharpness and allows it to absorb other flavors, such as from sausages, pork, or apples cooked with it.
A: No, pink discoloration is often a sign of spoilage caused by yeast growth, usually from not keeping the cabbage fully submerged during fermentation. It should be discarded.
A: Traditionally, there is little difference. However, some American “Bavarian-style” versions are made sweeter with the addition of sugar, which is less common in Germany.
A: People on low-sodium diets should be mindful of its salt content. Additionally, those with histamine intolerance or who take MAOI medication should consult a doctor due to its high histamine and tyramine levels.
