Plain cabbage cannot be canned in a water bath. It is a low-acid vegetable, and boiling water does not get hot enough to destroy Clostridium botulinum spores. The only cabbage products that belong in a water-bath canner are ones that have already been made acidic: fully fermented sauerkraut, and cabbage pickled in a tested vinegar brine.
That distinction is the whole job of this article. Search results are full of “easy brine” recipes that add a spoonful of vinegar to raw cabbage and process the jars for 20 minutes. Those methods are not research-tested. The recipes below follow USDA and National Center for Home Food Preservation (NCHFP) guidance, plus one long-standing Ball pickled-cabbage formula that Extension offices treat as a reliable pickled product.
If the goal is shelf-stable cabbage you can open in January, acidify it first. If the goal is cooked cabbage for soup, freeze it.
Why Water-Bath Canning Only Works After Cabbage Is Acidified
Water-bath canning is a boiling-water process. At sea level, that water never exceeds 212°F. That temperature kills yeasts, molds, and many bacteria, and it is enough for foods at pH 4.6 or lower because C. botulinum cannot grow in that acid range. Fresh cabbage sits well above that line. In a sealed jar with little oxygen, spores that survive the boil can later produce toxin.
There is a second problem that has nothing to do with vinegar. NCHFP has no tested process time for plain cabbage in a pressure canner either. Cabbage is denser and more rigid than spinach or other greens, so times written for greens cannot be borrowed. Cabbage also darkens and develops a harsh, cooked-brassica flavor when heat-processed as a plain vegetable. Researchers dropped the product rather than guess at a time.
Ball’s older Blue Books once listed plain cabbage. Those directions were removed in 1977. They should not be used.
What does work in a water bath:
- Fermented sauerkraut. Lactic acid produced during a complete ferment brings the pH low enough for boiling-water processing. NCHFP publishes this method.
- Pickled cabbage or cabbage relish. A tested recipe with 5% vinegar supplies the acid. Ball’s spiced red cabbage and NCHFP piccalilli are the two formulas most often cited by Extension.
Do not add cabbage to mixed vegetable soup or stew recipes for canning. NCHFP soup directions require that every vegetable already have its own tested process. Cabbage does not.
Choose the Right Method Before You Shred Anything
| Goal | Safe water-bath method | Time commitment | Texture in the jar |
|---|---|---|---|
| Tangy, probiotic-style cabbage for Reubens, pork, or soup | Ferment, then can sauerkraut | 3–6 weeks ferment + canning day | Soft, classic kraut |
| Sweet-sour slaw or German-style red cabbage | Ball-style pickled cabbage | 2 days (salt, drain, pack) | Firmer, vinegar-forward |
| Relish for hot dogs, beans, or ham | Piccalilli or similar tested relish | Overnight salt + cook-down | Chopped, saucy |
| Plain cooked cabbage for later frying or soup | Not water-bath safe | Freeze instead | Closest to fresh when thawed |
If you only have a water-bath canner and a pile of heads, pickled cabbage or sauerkraut are the two pantry options. Everything else belongs in the freezer or the refrigerator.
Equipment and Ingredients That Actually Matter
You need a boiling-water canner (or a deep stockpot with a rack and a lid), pint or quart Mason jars, new lids, a jar lifter, and a bubble remover. A steam canner is acceptable for these high-acid recipes if you follow the manufacturer’s fill and timing rules and still adjust for altitude.
Ingredient rules that change safety:
- Vinegar must be 5% acidity. Check the label. “Pickling vinegar” is usually 5%. Do not use homemade vinegar or wine vinegar of unknown strength.
- Use canning or pickling salt. Iodized table salt can cloud brine and, in fermentation, can interfere with the culture. Do not reduce the salt in sauerkraut; the ratio is part of the safety and fermentation control.
- Do not thin the vinegar. Adding extra water, skipping the overnight salt-and-drain step, or packing wet cabbage into a pickled recipe dilutes acid. Cabbage holds a lot of water; that is why tested pickle recipes salt it first.
- Fresh, firm heads. Start sauerkraut within 24 to 48 hours of harvest when you can. Soft or old cabbage ferments poorly and pickles to mush.
Find your altitude before you start. Processing times below 1,000 feet are the baseline; higher elevations need longer boils because water boils cooler.
Water-Bath Sauerkraut (NCHFP Method)
This is the official USDA/NCHFP path from shredded cabbage to shelf-stable jars. Fermentation is not optional. You cannot skip to the canner with salted raw cabbage and call it sauerkraut.
Yield: about 9 quarts from 25 pounds of cabbage Salt ratio if you scale: 3 tablespoons canning or pickling salt per 5 pounds shredded cabbage (¾ cup salt for the full 25-pound batch)
Ferment
- Discard outer leaves. Rinse heads, quarter, and core. Shred about as thick as a quarter.
- Work in 5-pound batches. Mix each batch with 3 tablespoons salt using clean hands until juice appears.
- Pack firmly into a food-grade crock, pail, or fermenter. The rim should sit 4 to 5 inches above the cabbage. Juice should cover the shreds. If it does not, add cooled brine made from 1½ tablespoons salt per quart of water.
- Weight the cabbage so it stays under brine. Cover with a clean towel.
- Hold at 70–75°F. At that range, kraut is usually fully fermented in 3 to 4 weeks. Cooler rooms (60–65°F) can take 5 to 6 weeks. Below 60°F fermentation may stall; above 75°F the kraut often turns soft.
- If you used a brine-filled bag as a weight, leave the crock alone until bubbling stops. If you used jars as weights, check two or three times a week and skim scum.
Fully fermented kraut can sit tightly covered in the refrigerator for several months. Canning is for pantry storage.
Can
Hot pack (better quality): Bring kraut and its juice slowly to a boil, stirring. Pack firmly into hot jars with the hot juice, ½-inch headspace.
Raw pack: Pack fermented kraut and juice firmly into jars, ½-inch headspace. Do not heat first.
Remove bubbles, wipe rims, apply lids fingertip-tight, and process in a boiling-water canner.
| Pack | Jar | 0–1,000 ft | 1,001–3,000 ft | 3,001–6,000 ft | Above 6,000 ft |
|---|---|---|---|---|---|
| Hot | Pints | 10 min | 15 min | 15 min | 20 min |
| Hot | Quarts | 15 min | 20 min | 20 min | 25 min |
| Raw | Pints | 20 min | 25 min | 30 min | 35 min |
| Raw | Quarts | 25 min | 30 min | 35 min | 40 min |
Times are from NCHFP Table 1 for sauerkraut.
Hot pack shortens the boil and usually gives a more even jar. Raw pack is acceptable; it just needs the longer time.
After processing, rest the canner 5 minutes off heat before lifting jars. Cool 12–24 hours. Remove rings, check seals, wash, label, and store cool and dark.
Spiced Pickled Red Cabbage (Ball Blue Book)
This is the pickled recipe Extension agents point to when someone wants German-style red cabbage on the shelf without fermenting. It is a two-day process because the salt draw is what keeps cabbage water from diluting the vinegar. Do not skip it.
Yield: about 5 quarts or 10 pints from 12 pounds cabbage (roughly 3 large heads)
Ingredients
- 12 pounds red or green cabbage, cored and shredded
- ½ cup canning or pickling salt
- 8 cups (2 quarts) red wine vinegar, 5% acidity
- 1 cup packed light brown sugar
- ½ cup mustard seed
- ¼ cup ground mace or nutmeg
- Spice bag: ¼ cup whole cloves, ¼ cup whole allspice, ¼ cup peppercorns, ¼ cup celery seed, 2 cinnamon sticks broken into pieces
- Ball Pickle Crisp, optional, per jar directions
Day 1. Layer shredded cabbage and salt in a large glass, stainless, or food-grade bowl. Cover. Stand 24 hours in a cool place.
Day 2. Drain. Rinse under cool water. Drain again on towel-lined trays about 6 hours so surface water is gone.
Prepare the canner, jars, and lids. Tie the whole spices in cheesecloth. Combine vinegar, brown sugar, mustard seed, mace, and the spice bag. Bring to a boil, then boil gently 5 minutes. Discard the bag.
Pack cabbage into hot jars to a generous ½ inch from the rim. Ladle hot liquid over the cabbage, still ½-inch headspace. Remove bubbles and add liquid if needed so the cabbage stays covered. Wipe rims, cap fingertip-tight.
Process pints or quarts 20 minutes in a boiling-water canner at 0–1,000 feet. Add 5 minutes at 1,001–3,000 feet, 10 minutes at 3,001–6,000 feet, and 15 minutes above 6,000 feet (standard water-bath altitude adjustment used with this 20-minute baseline).
Wait 5 minutes, then remove jars. Cool, check seals, store.
What you can and cannot change. Dry spices in the bag can be swapped or omitted. Do not cut the vinegar, swap in a weaker vinegar, skip the salt-and-drain, or add extra low-acid vegetables. Those changes are not tested.
Use this cabbage as you would jarred German red cabbage: with roast pork, sausages, or a sharp cheddar sandwich. It is not a stand-in for fresh slaw.
Piccalilli (NCHFP Cabbage Relish)
Piccalilli is the official NCHFP relish that uses a large share of cabbage. It is a cooked, chopped pickle, not shredded slaw, and it is processed in half-pint jars for a short time because the mixture is boiled down first.
Yield: 9 half-pints
- 6 cups chopped green tomatoes
- 1½ cups chopped sweet red peppers
- 1½ cups chopped green peppers
- 2¼ cups chopped onions
- 7½ cups chopped cabbage
- ½ cup canning or pickling salt
- 3 tablespoons whole mixed pickling spice
- 4½ cups vinegar (5%)
- 3 cups brown sugar
Combine the chopped vegetables with the salt, cover with hot water, and stand 12 hours. Drain and press in a clean cloth to remove as much liquid as possible. Tie spices in a bag. Heat vinegar and brown sugar with the bag to a boil; remove the bag. Add vegetables and boil gently 30 minutes, or until the volume is reduced by about half.
Fill hot sterile jars, ½-inch headspace. Process half-pints 5 minutes at 0–1,000 feet, 10 minutes at 1,001–6,000 feet, and 15 minutes above 6,000 feet.
This is the recipe to use when you want cabbage in a condiment, not as a side dish.
How to Run the Water-Bath Canner for These Recipes
- Wash jars. For recipes processed 10 minutes or more, hot clean jars are enough; you do not have to pre-sterilize. Piccalilli’s 5-minute process is why NCHFP specifies sterile jars for that one.
- Keep jars hot while you fill.
- Headspace is ½ inch on all three recipes above. Cabbage packed too tight can siphon; packed too loose can float above the brine.
- Remove air bubbles. Cabbage shreds trap pockets.
- Two-piece lids, fingertip-tight—not cranked down with a towel.
- Jars on the rack, water covering lids by 1 to 2 inches.
- Lid on the canner. Bring to a full rolling boil, then start the timer. A simmer does not count.
- If the boil breaks, bring it back and restart the time.
- When time is up, turn off heat, wait 5 minutes, lift jars straight up, and cool undisturbed.
A sealed lid that stays concave after the jar is cold is your check. Unsealed jars go in the refrigerator and get used soon.
Internet Recipes That Are Not Safe to Water-Bath
Several popular posts pack raw cabbage into quart jars, add about 1 teaspoon each of salt and sugar plus 1 tablespoon of vinegar, cover with boiling water, and process 20 minutes. That amount of vinegar does not acidify a jar of low-acid cabbage. The processing time is also not a tested process for plain cabbage. Treat those jars as a botulism risk, not a shortcut.
Other recipes to avoid for shelf-stable canning:
- Any “just salt and water” cabbage packed like green beans
- Cabbage added to vegetable soup, borscht, or stew for canning
- Old Ball or farm-bulletin times for plain cabbage from before 1977
- Cutting salt in sauerkraut “to make it healthier”
- Using 4% vinegar, rice vinegar of unknown strength, or leftover wine
Refrigerator pickled cabbage is a different product. A vinegar slaw kept cold is fine. The danger starts when the same loosely acidified mix is sealed and stored at room temperature.
Mistakes That Ruin Jars Even When the Recipe Is Good
Wrong salt in the crock. Iodized salt and some sea salts with additives can darken kraut or slow fermentation. Weigh or measure pickling salt.
Fermenting too warm. Soft, slimy kraut is usually a temperature problem, not a reason to can it anyway. If the ferment smells putrid rather than clean and sour, compost it.
Packing wet cabbage into pickled jars. The 24-hour salt and 6-hour drain exist so cabbage water does not dilute a 5% brine below a safe pH.
Guessing altitude. At 4,000 feet, a 20-minute pickled-cabbage process becomes 30 minutes. Short time at high elevation is under-processing.
Leaving rings on in storage. Rings hide a failed seal and trap moisture that rusts lids.
Tasting from a dubious jar. Botulinum toxin has no reliable smell or look. If a jar of low-acid food was processed by an untested method, do not taste it to “check.” Discard it without tasting, with the contents in a sealed bag in the trash, and clean the area with diluted bleach per standard home-canning disposal advice.
What to Do With the Jars Once They Are Sealed
Canned sauerkraut behaves like commercial kraut after it is heated in the canner: the live culture is gone, but the acid and flavor remain. Rinse it if you want less salt, then use it on sausages, in soup, or fried with onions.
Pickled red cabbage is already seasoned. Warm it gently with a little of its brine, or serve it cold as a condiment. It will not crisp up like fresh slaw.
Piccalilli goes on beans, eggs, cheese, and grilled meat.
None of these jars replace shredded cabbage in egg rolls or stir-fries. For that texture, freeze.
If You Want Cooked Cabbage Later, Freeze It
NCHFP and state Extension services recommend freezing when you want cabbage that still tastes like cabbage. A typical method: select solid heads, remove coarse leaves, cut or separate, blanch about 1½ minutes, chill in ice water, drain, pack with ½-inch headspace, and freeze. Quality is better than any historical plain-canned product.
You can also keep finished sauerkraut in the refrigerator for months and skip the canner entirely if pantry space is not the point.
Frequently Asked Questions
Can I water-bath can raw cabbage if I add extra vinegar? Only inside a tested pickled recipe with a stated vinegar amount, vegetable weight, and process time. A splash of vinegar in a quart of cabbage is not that recipe.
Can I pressure-can plain cabbage instead? NCHFP still does not publish a process. Quality is poor, heat penetration is uncertain, and cabbage is barred from the tested mixed-vegetable and soup formulas. Freezing or pickling is the researched answer.
Is homemade kimchi safe to water-bath can? NCHFP’s tested fermented-cabbage canning process is written for sauerkraut made with cabbage and salt only. Kimchi recipes add other low-acid ingredients and different salt levels. Do not borrow sauerkraut times for an untested kimchi formula. Refrigerate kimchi or use a recipe specifically tested for canning.
Why do some blogs process pickled cabbage 10 minutes and others 20? Ball’s spiced cabbage is a 20-minute process. Some quick-pickle blog recipes use shorter times that were never laboratory-tested for that pack. Use the time that belongs to the recipe you actually followed.
Do I have to use red wine vinegar for the Ball cabbage? The published formula uses 5% red wine vinegar. White vinegar at 5% is the usual substitute in pickles when color is not the point; changing vinegar type can change flavor and color. Do not change the volume or the 5% strength.
How long do sealed jars last? Store in a cool, dark place and use within a year for best quality. Always check the seal and the look of the food before eating. If the lid flexes, the food spurts, or the smell is off, do not eat it.
Can I make a small batch of sauerkraut? Yes. Keep 3 tablespoons pickling salt per 5 pounds cabbage and use a container deep enough to keep the shreds under brine. Processing times in the table do not change for a smaller number of jars.
Water-bath canning cabbage is straightforward once the acid is real. Ferment it into sauerkraut, or pickle it with a tested brine. Skip the shortcuts that treat a tablespoon of vinegar like a force field. The extra day of salting, or the extra weeks in a crock, is what makes the jar safe to leave on a shelf.
