7 Best Unpasteurized Sauerkraut Brands (2026 Guide)
Unpasteurized sauerkraut is raw, lacto-fermented cabbage that has not undergone heat treatment, meaning it retains live lactic acid bacteria and enzymes that pasteurized versions lose. If you are shopping for real, probiotic-rich kraut, the challenge is not finding sauerkraut — it is finding sauerkraut that is actually alive. Many products labeled "fermented" are heat-processed for shelf stability, and a surprising number of so-called raw brands vary by batch. This guide walks you through how to verify what you are buying, profiles the most reliable unpasteurized sauerkraut brands on the U.S. market, and answers the store-specific questions — Walmart, Trader Joe's, Whole Foods — that most articles skip. You will also learn how to store raw kraut properly, how it fits into gut-health thinking, and where microbiome testing may add useful context to what you are already observing.
What Is Unpasteurized Sauerkraut and Why It Matters
Sauerkraut at its most basic is cabbage and salt. The magic happens during lacto-fermentation, a process in which naturally occurring lactic acid bacteria — primarily Leuconostoc, Lactobacillus, and Pediococcus species — convert cabbage sugars into lactic acid. That acid drops the pH, preserves the cabbage, gives sauerkraut its tang, and creates an environment where spoilage organisms struggle to survive. In traditional preparation, nothing is heated after fermentation. The result is a living food containing live cultures, active enzymes, and a complex mix of fermentation metabolites.
Pasteurized sauerkraut starts from a similar process but is then heated — often to temperatures above 160°F — to extend shelf life and allow unrefrigerated distribution. Heat processing kills the bacteria responsible for fermentation. The kraut still tastes sour and still contains fiber and some organic acids, but the live cultures are gone. For anyone specifically seeking sauerkraut for probiotics and digestive health support, that distinction is the whole ballgame.
Why "Raw" Matters for Probiotics
Research on fermented foods has grown substantially over the past decade. Stanford researchers published a 2021 study in Cell showing that a diet high in fermented foods (including sauerkraut, kimchi, yogurt, and kefir) increased gut microbiome diversity and altered immune markers in healthy adults over 10 weeks. That is a meaningful finding — but it is a study of fermented foods broadly, not of one brand, and not proof that sauerkraut alone will change your health.
What we can say with reasonable confidence is that raw, refrigerated sauerkraut carries live lactic acid bacteria at the time of purchase, while pasteurized kraut does not. Whether those bacteria colonize your gut long-term is a separate and more complicated question. Many probiotic strains are transient — they pass through rather than take up permanent residence. Still, transient exposure to live cultures and their fermentation by-products may support the gut environment, and some evidence suggests regular consumption of fermented foods can influence microbiome composition and function. Individual responses vary considerably.
Visual and Textural Cues
Raw sauerkraut tends to look and behave differently from its pasteurized cousin. It may appear slightly cloudy in the brine (a normal sign of active fermentation), can have a livelier crunch, and often needs refrigeration from the moment it reaches the store. Pasteurized kraut is usually shelf-stable, bright, and uniform. None of these visual cues is a substitute for reading the label, but they provide useful context when you are standing in the refrigerated aisle.

If you want a deeper picture of how your own gut responds to fermented foods and dietary changes, a personalized microbiome analysis can offer educational insights into the composition of your gut bacteria over time. It is not a diagnostic tool and cannot tell you whether a specific jar of kraut "worked," but it can help you understand the broader microbial context in which dietary choices play out.
How to Identify True Unpasteurized Sauerkraut
The single most reliable way to know if sauerkraut is unpasteurized is to read the label and check where it is stored in the store. Marketing language can be loose, but regulated label claims are not — and location in the store tells you a lot about what is inside the jar.
A Step-by-Step Label and Shelf Check
- Look for the word "raw" or "unpasteurized" on the front label. Reputable raw brands use these terms deliberately. If neither word appears, assume the product is heat-processed until you can confirm otherwise.
- Check the ingredient list for vinegar. Traditional unpasteurized sauerkraut is made with cabbage and salt only. Vinegar-based "sauerkraut" is essentially pickled cabbage — it can be tasty, but it is not lacto-fermented and contains no live cultures from fermentation.
- Look for preservatives. Sodium benzoate, potassium sorbate, and similar preservatives are incompatible with a truly live product. Their presence typically means the kraut is not relying on active fermentation for stability.
- Find the refrigerated section. Genuinely raw sauerkraut almost always requires refrigeration. It may sit in the refrigerated produce area, the deli case, or a dedicated fermented-foods section. If the same brand is sold unrefrigerated on a dry shelf, read carefully — that version is likely pasteurized even if a refrigerated sibling is raw.
- Search for "live cultures" or "probiotic" language. This is not a regulated claim in the same way "raw" is, but it is a strong signal of intent. Pair it with the refrigerated location and a simple ingredient list for the highest confidence.
- Check the brand's own website. Many raw brands publish clear statements about pasteurization. If a brand is cagey about the topic online, that itself is information.
Packaging Nuances Worth Knowing
Raw sauerkraut often comes in glass jars, plastic tubs, or sealed bags. Ba-Tampte is a well-known example of bag-packaged refrigerated kraut. Bags allow for some gas expansion and are common in the refrigerated section of kosher and deli-focused retailers. Glass jars may show a slight bulge or release gas when opened — a sign of ongoing fermentation, not spoilage. Vacuum-sealed "easy open" lids and long unrefrigerated shelf lives are usually red flags for raw products.
One caveat worth flagging: even brands that commit to raw production can have batch variation, especially smaller producers. Always confirm on the specific container in front of you rather than relying on what you remember about a brand.
Best Unpasteurized Sauerkraut Brands to Buy
The brands below are selected because they have a documented track record of producing raw, refrigerated sauerkraut with straightforward ingredient lists. Availability varies by region and by store. Where a brand's status has been reported to vary by batch or product line, that is noted.

1. Bubbies
Bubbies is one of the most widely recognized names in refrigerated raw sauerkraut in the U.S. The company's classic product is made with cabbage, water, and salt, and it is sold refrigerated. Bubbies has historically positioned its sauerkraut as raw and containing live cultures. It is stocked at Whole Foods, many natural grocers, and increasingly at mainstream supermarkets. Flavor is bright and salty with a firm, classic crunch. Ingredient list is minimal, which is exactly what you want to see.
2. Cleveland Kraut
Cleveland Kraut has become a staple in the refrigerated fermented-foods category and is broadly distributed — including at Walmart, Target, Kroger, and Whole Foods in many regions. The brand produces a range of flavored krauts (classic caraway, beet red, gnar gnar) that are lacto-fermented and sold refrigerated. Availability is one of its biggest strengths; you can often find it in mainstream grocery refrigerated sections. As always, check the specific label on the jar for the "raw" indicator.
3. Wildbrine
Wildbrine makes raw, refrigerated sauerkraut and kimchi, typically found at Whole Foods, Sprouts, natural grocers, and many regional co-ops. The brand emphasizes vegan, non-GMO ingredients. Its krauts often include additional vegetables and seasonings, so read the ingredient list if you are looking for a strict cabbage-and-salt product. Wildbrine is widely viewed as a reliable raw option in the natural channel.
4. Sonoma Brinery
Sonoma Brinery is a smaller producer with a farmer's-market feel. Its sauerkraut is refrigerated, lacto-fermented, and typically sold in glass jars at specialty grocers, some Whole Foods locations, and regional natural retailers. It is not as widely distributed as Cleveland Kraut or Bubbies, so availability can be spotty depending on your region. When you can find it, it is a solid raw option.
5. Olive My Pickle
Olive My Pickle is primarily an online-first brand selling fermented vegetables, including raw sauerkraut, direct to consumers. This is worth knowing if your local stores do not carry a reliable raw option. Because the product ships refrigerated (or with cold packs), it is one of the more accessible online options for people in areas without strong natural-grocery coverage. Shipping costs and cold-chain logistics are considerations.
6. Ba-Tampte
Ba-Tampte is a long-standing kosher brand whose refrigerated sauerkraut is commonly sold in bags in the refrigerated section, particularly at kosher markets, some mainstream supermarkets, and delis. The product is traditionally fermented and refrigerated. It is a good example of a bag-packaged raw-style kraut — useful to know if you are scanning the refrigerated case and expecting only jars.
7. Farmhouse Culture
Farmhouse Culture has been a well-known name in raw fermented foods, with refrigerated sauerkraut products sold at natural grocers and Whole Foods in many regions. One important caveat: brand ownership and product lines have changed over time, and availability has fluctuated. If you are looking at a Farmhouse Culture product, check the current label rather than relying on older reviews or articles about the brand.
8. Amish Wedding and Small-Batch Amish Producers
Amish Wedding and similar brands associated with Amish and Mennonite producers are often found in specialty stores, farmers' markets, and some regional groceries. Many of these products are traditional lacto-fermented krauts, but packaging, pasteurization, and distribution vary by producer. If you see one of these jars in a refrigerated case, it is worth reading the label to confirm raw status. Smaller producers may not advertise "raw" prominently, so you may need to look for ingredient and storage cues.
9. Trader Joe's Branded Kraut
A common question. Trader Joe's sells sauerkraut in more than one format, and the answer depends on the specific product. Its refrigerated branded sauerkraut has historically included both raw and pasteurized products depending on the item. If you are at Trader Joe's and want raw, do not assume — look at the label and confirm it is refrigerated, contains only cabbage and salt, and describes the product as raw or containing live cultures.
10. Regional and Local Producers
Beyond national brands, local fermented-food companies are often the most reliable raw options in your area. Many regional producers sell only through farmers' markets, CSAs, or local co-ops, where the person selling it can tell you exactly how it was made. If finding a national brand with the right credentials is difficult in your area, local is often the better path.

Where to Buy Unpasteurized Sauerkraut Near You
Because raw sauerkraut requires refrigeration, availability is uneven. What follows is a retailer-by-retailer breakdown oriented around where you are most likely to find a genuinely raw product. Treat this as a starting point, not a guarantee — product mix changes frequently, and stores differ by region.
Walmart
The direct answer to the common question: yes, many Walmart stores carry unpasteurized sauerkraut — typically in the refrigerated section near the deli, produce, or specialty refrigerated case. Cleveland Kraut is the brand most likely to appear, and Bubbies is also carried in some larger locations. Availability varies significantly by store size and region. The safest approach at Walmart is to head to the refrigerated section and look for a jar with "raw" or "unpasteurized" on the label, then confirm the ingredient list contains only cabbage and salt (and possibly water).
Trader Joe's
Trader Joe's keeps shoppers guessing because its own private-label products rotate. Its branded sauerkraut has historically included both raw and pasteurized products depending on the specific item and season. However, Trader Joe's frequently carries third-party refrigerated sauerkraut from brands such as Cleveland Kraut or regional producers. If you want raw kraut at Trader Joe's, do not assume the Trader Joe's label is raw — check the label on each jar and confirm. If the branded version is pasteurized, look in the same refrigerated case for a third-party raw brand.
Whole Foods
Whole Foods has the strongest overall track record for stocking raw refrigerated sauerkraut. Brands commonly seen include Bubbies, Wildbrine, Cleveland Kraut, and various regional producers. You will often find them in the refrigerated produce area or a dedicated refrigerated fermented-foods section. Staff at Whole Foods are typically knowledgeable and can confirm which products are raw if the label is ambiguous.
Target
Target has expanded its refrigerated offerings significantly. Cleveland Kraut is commonly stocked at larger Target locations with full grocery sections. Availability varies by store format. If you have a SuperTarget or a store with a full grocery layout, your odds are better. Target's selection is not as deep as Whole Foods', but it is often better than people expect.
Kroger, Safeway, and Mainstream Supermarkets
Large mainstream chains increasingly carry refrigerated sauerkraut from Cleveland Kraut and sometimes Bubbies, typically in the refrigerated produce or deli area. The southern and coastal chains may stock regional raw brands instead. Ask a staff member to point you to the refrigerated fermented-foods area — it is usually not next to the canned sauerkraut.
Sprouts, Natural Grocers, and Co-ops
These are strong bets for raw brands, especially Wildbrine, Bubbies, and local producers. Co-ops in particular often carry the widest variety of regional raw sauerkraut, and staff can usually speak to how the product was made.
Costco
Costco occasionally carries raw refrigerated sauerkraut in larger tubs, but the selection rotates and is not consistent. When it is available, it is usually a well-known brand sold as a two-pack or larger container. If you see it, verify the label on the container itself rather than assuming from the brand.
Farmers' Markets and Local Producers
If you have access to a farmers' market with a fermented-food vendor, this is often the single most reliable way to buy genuinely raw sauerkraut. You can ask about fermentation time, salt content, and whether the product has been heat-processed. Transparency is a significant advantage of buying directly from producers.
Online Retailers
Amazon, the brands' own websites, and specialty online grocers sell refrigerated-and-shipped raw sauerkraut. Olive My Pickle is a prominent online-first brand. Shipping with cold packs or expedited delivery is the norm for raw products. Expect higher cost and seasonal shipping limitations for warm-weather destinations. If local options are truly limited, online is a reasonable option — just factor in shipping cost and temperature risk.
Unpasteurized vs. Pasteurized: Navigating Shelf-Stable Options
Most sauerkraut on the American grocery shelf is pasteurized or made with vinegar. That is not a knock against those products — many are tasty, affordable, and durable. But if your goal is probiotic sauerkraut rather than just the flavor of kraut, it is essential to distinguish between these categories.
What "Shelf-Stable" Really Means
Shelf-stable sauerkraut does not need refrigeration until it is opened. To achieve that, manufacturers either pasteurize (heat-treat) the product or acidify it with vinegar. Silver Floss sauerkraut, a widely distributed canned brand, is a useful example: it is a shelf-stable, heat-processed product sold in cans, and its role is flavor, convenience, and cooking. It is not marketed as raw and does not contain live cultures in the way a refrigerated raw product does. That does not make it a bad product — it just means it is not the right choice if live probiotics are the goal.

Where Pasteurized Fits
Pasteurized sauerkraut is the sensible choice for cooked applications (think pork and kraut, sauerkraut soups, or sauerkraut on sausages) where the live cultures would not survive cooking anyway. It is also more practical for pantry storage and long shelf life. The trade-off is probiotic content. Pasteurized kraut still provides fiber, vitamin C (somewhat reduced by heat), and the flavor of fermented cabbage. If you are eating sauerkraut mostly as a condiment for flavor, pasteurized is a reasonable option.
Vinegar "Sauerkraut"
Some products labeled sauerkraut are actually pickled cabbage made with vinegar and without lacto-fermentation. These products do not contain the same live cultures even if they are refrigerated. The ingredient list is the tell: if vinegar appears as a primary ingredient, it is not traditional lacto-fermented sauerkraut. Some products combine both approaches — vinegar plus fermentation — in which case the vinegar will tend to suppress or bypass the fermentation pathway.
How to Ensure Your Sauerkraut Stays Unpasteurized
Buying raw sauerkraut is step one. Keeping it in the state that makes it interesting is step two. Heat is the main enemy. Once you are home, the product should remain refrigerated at or below about 40°F. That is the temperature where the live cultures slow down rather than continue actively fermenting or degrading.
General Storage Principles
- Keep it cold. Refrigerate immediately after purchase and after each serving. Do not leave a raw jar on the counter while prepping dinner for long periods.
- Keep it submerged in brine. Raw kraut should sit under its liquid. Exposure to air can encourage surface yeasts and molds. Use a clean utensil to press the kraut back down if needed.
- Use clean utensils. Scoop with a clean fork or spoon, not the same utensil you used to taste and then return to the jar.
- Watch for gas. A slightly pressurized jar or a small bulge can indicate ongoing fermentation. That is normal in a live product; open carefully.
- Do not freeze the jar. Freezing breaks cell walls and changes texture, and repeated freeze-thaw cycles degrade quality.
Kahm Yeast, Bloom, and Spoilage
A whitish film or slight bloom on the surface of raw sauerkraut is often kahm yeast — a harmless surface yeast that can appear when oxygen is present. It is usually a cosmetic issue; skim it and continue. That said, kahm yeast should not be confused with fuzzy green, black, or pink mold, which indicates actual spoilage and is a discard situation. A good rule for raw fermented foods: if it smells and looks like kraut, it probably is fine; if it smells rotten, looks fuzzy and colorful, or is slimy throughout, discard it. When in doubt, throw it out — no jar of kraut is worth a food safety risk.
Does Cooking Destroy the Cultures?
Yes, heating raw sauerkraut above roughly 115–120°F will gradually reduce live culture counts, and normal cooking temperatures will effectively eliminate them. If your goal is live probiotics, add raw kraut to a dish at the end or serve it cold. If your goal is flavor in a cooked dish, use pasteurized kraut (or accept that the cultures in raw kraut will not survive cooking).
Key Takeaways
- Unpasteurized sauerkraut is raw, lacto-fermented cabbage that has not been heat-treated and therefore retains live lactic acid bacteria.
- The most reliable verification method is a combination of label reading and store location: look for "raw" or "unpasteurized," a simple cabbage-and-salt ingredient list, and refrigeration.
- Brands with strong raw-product reputations include Bubbies, Cleveland Kraut, Wildbrine, Sonoma Brinery, Olive My Pickle, Ba-Tampte, and regional producers.
- Walmart does carry unpasteurized sauerkraut in many stores, typically in the refrigerated section, though availability varies by region and store format.
- Trader Joe's sells both raw and pasteurized sauerkraut depending on the specific product — always check the label rather than assuming.
- Silver Floss and other canned shelf-stable brands are pasteurized and do not contain live cultures, though they are fine for cooked applications.
- Pasteurized and vinegar-based krauts are legitimate products, but they are not probiotic sauerkraut — the goal determines which you should choose.
- Raw sauerkraut should be kept refrigerated, submerged in brine, and handled with clean utensils.
- Kahm yeast is harmless; fuzzy colored mold is not. Trust your senses and discard anything clearly spoiled.
- Microbiome testing can offer educational insight into your gut ecosystem, but it is not a diagnostic tool and cannot confirm the effect of any single food on your digestion.
Frequently Asked Questions
Is Bubbies sauerkraut unpasteurized?
Bubbies has historically produced raw, refrigerated sauerkraut with a simple ingredient list of cabbage, water, and salt, and the brand markets its product as containing live cultures. That said, always confirm the current label on the jar you are purchasing, because product formulations can change. The refrigerated location and the "raw" or live cultures language on the label are the key indicators.
Does Walmart carry unpasteurized sauerkraut?
Many Walmart locations do carry unpasteurized sauerkraut, most commonly in the refrigerated section near the deli or produce, with Cleveland Kraut being one of the most widely stocked brands and Bubbies appearing in larger stores. Availability is not uniform — small-format stores may not stock it at all. The label check matters more than the store when you are confirming raw status.
Is Trader Joe's sauerkraut unpasteurized?
It depends on the specific product. Trader Joe's has sold both raw and pasteurized sauerkraut under its own label at different times and in different regions, so the Trader Joe's name alone does not tell you which you are getting. Trader Joe's also frequently carries third-party raw kraut brands. Check the label and confirm refrigeration plus "raw" or live cultures language before buying.
How do I know if my sauerkraut is pasteurized or unpasteurized?
Look for three signals together: the word "raw" or "unpasteurized" on the label, an ingredient list that is essentially cabbage and salt (no vinegar, no preservatives), and storage in the refrigerated section. If any of those is missing, treat the product as likely pasteurized unless the brand's website or packaging explicitly states otherwise. When in doubt, contact the manufacturer.
Is Silver Floss sauerkraut unpasteurized?
Silver Floss sauerkraut is a shelf-stable, canned product and is not a raw, refrigerated, live-culture product. It is heat-processed for shelf stability. It is a legitimate choice for flavor in cooked dishes, but if your goal is probiotic sauerkraut, Silver Floss is not the product you are looking for.
What is the best raw unpasteurized sauerkraut for probiotics?
There is no single "best" brand, because what you actually want is any product that is genuinely raw, refrigerated, and made with a simple ingredient list. Bubbies, Cleveland Kraut, Wildbrine, and Sonoma Brinery are consistently regarded as raw options in the U.S. market, and regional producers are often excellent. The specific strains and counts vary by product and batch, and individual responses to fermented foods differ widely.
What is the difference between raw and pasteurized sauerkraut?
Raw sauerkraut has not been heat-treated after fermentation, so it retains live lactic acid bacteria and active enzymes. Pasteurized sauerkraut has been heated, which kills the live cultures and extends shelf life but removes the probiotic content. Raw kraut typically requires refrigeration; pasteurized kraut is often shelf-stable. Both are recognizable as sauerkraut in flavor and texture, but they serve different purposes.
Can unpasteurized sauerkraut make you sick?
Raw fermented foods are generally safe for most healthy adults when properly made and refrigerated, and the low pH of properly fermented sauerkraut discourages pathogenic growth. However, individuals with compromised immune systems, pregnant people, and young children should discuss raw fermented foods with their healthcare provider. Spoiled product — characterized by fuzzy mold, an off smell, or sliminess throughout — should be discarded, not eaten.
Does unpasteurized sauerkraut need to be cooked?
No. Raw sauerkraut is typically eaten cold or at room temperature, as a condiment or side. Cooking will destroy the live cultures, so if you want the probiotic benefit, add it after cooking or eat it raw. If you are using it in a hot dish purely for flavor, cooking is fine — just recognize that the culture benefit is lost.
How should I store unpasteurized sauerkraut?
Keep it refrigerated at or below about 40°F, keep the kraut submerged in its brine, and use clean utensils each time. Some gas release or slight jar pressure is normal for a live product. Avoid leaving the jar out at room temperature for extended periods. Do not freeze the jar unless you accept texture changes.
Is it safe to eat unpasteurized sauerkraut during pregnancy?
This is a personal medical question best directed to your healthcare provider. General food-safety guidance in pregnancy often emphasizes caution with raw and unpasteurized products because of listeria and other pathogen concerns, though properly fermented, refrigerated sauerkraut has a low pH that discourages many pathogens. Because individual risk factors vary, ask your OB or clinician before adding raw sauerkraut to your diet during pregnancy.
Why does my raw sauerkraut taste fizzy or bubbly?
A slight fizziness or tingling sensation is a normal sign of ongoing fermentation and dissolved carbon dioxide in a live product. It is not typically a sign of spoilage. If the kraut also smells off, looks fuzzy, or is slimy throughout, discard it. The combination of appearance, smell, and texture is more reliable than a single sensory cue.
Conclusion
Finding unpasteurized sauerkraut comes down to three practical habits: read the label for "raw" or "unpasteurized," confirm the ingredient list is essentially cabbage and salt, and locate the product in the refrigerated section. Brands like Bubbies, Cleveland Kraut, Wildbrine, Sonoma Brinery, Olive My Pickle, Ba-Tampte, and regional producers reliably offer raw products, and mainstream retailers — including Walmart, Target, Whole Foods, and increasingly Kroger and Safeway — stock at least some of them. Trader Joe's is a case where the label, not the brand name, tells you what you are getting.
Raw, pasteurized, and vinegar-based krauts are not interchangeable. If your goal is live cultures and the potential gut-health relevance that comes with them, you need the raw, refrigerated version — and you need to store it cold. If your goal is flavor in cooked dishes, pasteurized is efficient and sensible.
Note also that individual responses to fermented foods vary. Some people feel digestive changes quickly; others notice little. Underlying reasons for symptoms or digestive patterns are often multiple, and a jar of sauerkraut is not a diagnostic tool. If you are curious about the microbial context in which your diet choices play out, understanding your gut microbiome through a home test can offer educational insight into your own bacterial composition over time. It is one input among many — useful for context, not a substitute for medical evaluation, and not a way to confirm what a single food did or did not do.
