You can water-bath can beets only if they are pickled in a tested vinegar brine. Plain beets packed in water are a low-acid vegetable. A boiling-water bath never gets hot enough to destroy Clostridium botulinum spores, so those jars are not safe on a pantry shelf.
If you want shelf-stable beets without a pressure canner, pickle them. Vinegar drops the pH to 4.6 or lower, which stops those spores from growing. Then a water bath is the approved method. This article covers that safety split first, then walks through the National Center for Home Food Preservation pickled-beet recipe, processing times by altitude, and the mistakes that most often spoil a batch.
Can You Water Bath Can Beets?
Short answer: not in water alone.
| Product | Safe method | Why |
|---|---|---|
| Plain beets in water or their own juice | Pressure canner only | Low-acid food; spores survive 212°F |
| Pickled beets in a tested vinegar brine | Boiling-water bath or steam canner | Acidified to pH 4.6 or below |
| Refrigerator pickled beets | No canning needed | Keep refrigerated and use within about a month |
No extra minutes in a stockpot change this. Longer boiling still tops out at the boiling point of water. Extra time does not raise temperature. Only pressure canning reaches the 240°F range needed for plain vegetables.
That is why old “water bath the beets for two hours” advice is unsafe. Extension services and the USDA have recommended pressure canning plain beets since the 1920s. Documented botulism cases have been tied to water-bathed plain beets.
Why Plain Beets Cannot Go in a Water Bath
Beets grow in soil. C. botulinum spores live in soil and hitch a ride on root vegetables even after a good scrub. On a raw beet they are harmless. Inside a sealed jar they have everything they need if the food is moist, low-acid, and oxygen-free: they can germinate and produce toxin without changing the look or smell of the food.
A water bath kills molds, yeasts, and many vegetative bacteria. It does not reliably kill botulinum spores. Acid does the safety work in pickles. Heat does the safety work in pressure-canned vegetables. Mixing those two jobs is how people get into trouble.
Two more practical rules follow from this:
- Do not can the cooking water the beets were boiled in. That water picked up soil and debris from the skins. Official directions say to drain and discard it, then use fresh boiling water (plain beets) or a fresh vinegar brine (pickled beets).
- Do not invent a “lightly pickled” recipe with a splash of vinegar. Tested recipes use a measured amount of 5% vinegar. Penn State Extension notes that research-tested pickled beet recipes use more than ½ cup vinegar per pint, and that a weak brine (too much water, too little vinegar) will not control botulism.
What You Need for Water-Bath Pickled Beets
You do not need a pressure canner for this recipe. You do need a pot tall enough to cover the jars with at least 1 inch of boiling water (2 inches is better for a 30-minute process, because water evaporates).
Equipment
- Water-bath canner or a deep stockpot with a rack
- Pint or quart canning jars with new lids and rings
- Jar lifter, funnel, and a non-metallic bubble remover
- Cheesecloth or a spice bag
- Gloves if you want to avoid stained hands
Ingredients for about 8 pints (NCHFP pickled beets)
- 7 pounds beets, 2 to 2½ inches in diameter
- 4 cups vinegar, 5% acidity (white or cider)
- 1½ teaspoons canning or pickling salt
- 2 cups sugar
- 2 cups water
- 2 cinnamon sticks
- 12 whole cloves
- 4 to 6 onions, 2 to 2½ inches in diameter, optional
Yield is about 8 pints. Baby beets (1 to 1½ inches) can be packed whole; onions can be left out of that variation.
Use vinegar labeled 5% acidity. Do not dilute it further. Do not swap in balsamic, rice vinegar of unknown strength, or leftover wine. Sugar and spices can be adjusted in many pickle recipes for taste, but the vinegar-to-water ratio cannot. This formula is 2 parts vinegar to 1 part water.
How to Choose and Prep Beets
Small to medium beets can better. Roots larger than about 3 inches often turn woody. Sort by size so they cook evenly.
Leave 1 inch of stem and the taproot on while they boil. That reduces color bleed so the finished slices stay deep red instead of pale. Scrub well; dirt is the issue, not the pigment.
Cook similar sizes together in boiling water until tender, about 25 to 30 minutes for the pickled recipe. Drain and discard that liquid. Cool just enough to handle, slip off the skins, trim stems and roots, and slice ¼ inch thick. For baby beets, pack them whole after peeling.
Keep the peeled beets warm. This is a hot-pack recipe. Cold beets in hot brine give you uneven heating and more siphoning later.
Step-by-Step: Water Bath Canning Pickled Beets
- Heat the jars. Wash jars in hot soapy water and keep them hot. Prepare lids according to the manufacturer.
- Make the brine. Combine vinegar, salt, sugar, and fresh water. Tie cinnamon and cloves in cheesecloth and add the bag. Bring to a boil.
- Simmer the vegetables. Add sliced beets and onions. Simmer 5 minutes. Remove the spice bag. That short simmer starts acid moving into the beets before they go in the jar.
- Pack. Fill hot jars with beets and onions, leaving ½-inch headspace. Cover with hot vinegar solution, still ½-inch headspace. Slide a plastic spatula around the inside to release trapped air. Add more brine if the level drops.
- Seal. Wipe rims with a clean damp cloth. Apply lids and screw bands fingertip-tight. Over-tightening can buckle lids and cause seal failure.
- Process. Lower jars onto the rack in the canner. Water should cover lids by 1 to 2 inches. Cover the pot, return to a full rolling boil, then start the timer.
Processing time for pickled beets (pints or quarts, hot pack)
| Altitude | Time |
|---|---|
| 0–1,000 ft | 30 minutes |
| 1,001–3,000 ft | 35 minutes |
| 3,001–6,000 ft | 40 minutes |
| Above 6,000 ft | 45 minutes |
These times come from the NCHFP boiling-water table for pickled beets. Pints and quarts use the same times in this recipe.
- Cool and check. When the time is up, turn off the heat, remove the canner lid, and wait 5 minutes before lifting jars. That pause reduces siphoning. Set jars on a towel with space between them. Leave them undisturbed 12 to 24 hours. Then remove rings, check that lids are concave and do not flex, wash the jars, label, and store.
Unsealed jars go in the refrigerator and should be eaten soon. Do not reprocess a sealed-looking jar days later “just in case.”
What “Done” Looks Like After Processing
A good jar has a sealed lid, liquid covering most of the beets, and no spurting when you open it later. Some liquid loss (siphoning) is common with dark, starchy vegetables. If the jar sealed and at least half the contents stay covered, quality drops before safety does. Uncovered slices may fade. Refrigerate any jar that lost a large amount of brine or never sealed.
Wait a few days before eating. Flavor evens out as the brine moves through the slices.
Store in a cool, dark place. Best quality is usually 12 to 18 months. Always inspect before opening: bulging lids, spurting liquid, off odors, or mold mean the jar is discarded. Do not taste to “check.”
Mistakes That Make Water-Bath Beets Unsafe or Disappointing
Using a family recipe with too little vinegar. Grandmother’s brine may taste better and still be unsafe. Stay with a tested ratio or a published NCHFP/Ball recipe.
Water-bathing plain beets “because they’ll be cooked later.” Botulinum toxin can form in the sealed jar during storage. Cooking later is not a plan; it is a last-resort emergency measure for food you already suspect, and suspect jars should be discarded, not served.
Skipping altitude adjustments. At higher elevations water boils cooler. The extra minutes in the table compensate for that.
Filling with cooking water. Official directions discard it. Fresh brine or fresh boiling water only.
Leaving stems and roots off before the first boil. You will lose more color into the pot and end up with paler slices.
Overcooking before packing. For pickles, cook until tender enough to peel, not until the beets collapse. They get more heat in the canner.
Changing jar size without a tested process. This recipe is written for pints and quarts. Half-pints are sometimes processed like pints in pickle recipes, but do not pack gallons or oversized decorative jars.
Reusing lids or overtightening bands. New lids. Fingertip-tight rings.
If You Want Plain Beets Instead of Pickled
Use a pressure canner. There is no tested water-bath process for beets in water.
NCHFP directions in brief: trim tops leaving 1 inch of stem and the roots, scrub, boil 15 to 25 minutes until skins slip, peel while still warm, leave baby beets whole, cut larger ones into ½-inch cubes or slices. Pack hot beets with fresh boiling water and 1-inch headspace. Salt is optional (1 teaspoon per quart). Do not use the beet cooking water.
Pressure process (hot pack)
- Pints: 30 minutes
- Quarts: 35 minutes
- Dial-gauge: 11 psi at 0–2,000 ft (increase psi at higher elevations)
- Weighted-gauge: 10 psi at 0–1,000 ft; 15 psi above 1,000 ft
Need about 13½ pounds of topped beets for 9 pints, or 21 pounds for 7 quarts.
If you do not own a pressure canner and do not want pickled flavor, freeze cooked, peeled beets instead.
Pickled vs. Pressure-Canned: Which Batch Should You Make?
Choose pickled water-bath beets if you want pantry jars without buying a pressure canner, you like a sweet-tart side dish, or you are putting up a small harvest.
Choose pressure-canned plain beets if you want them for borscht, roasting, salads with goat cheese, or any recipe where vinegar would fight the other flavors.
You can do both from one harvest: pickle the small, tender roots and pressure-can the rest.
Frequently Asked Questions
Can I water-bath beets if I add lemon juice instead of a full pickle brine? No. There is no tested lemon-juice water-bath process for plain beets. Use a complete pickled-beet recipe or pressure can.
White vinegar or apple cider vinegar? Both work if they are 5% acidity. White keeps the color brighter. Cider adds a rounder flavor.
Can I cut the sugar? Sugar is for flavor and texture, not the main safety control. NCHFP also publishes a no-sugar pickled beet recipe that uses more vinegar (6 cups vinegar and 3 cups water with Splenda) and is processed the same 30 minutes at 0–1,000 ft, pints only in that version. Do not just delete sugar from the standard recipe and assume the original process still applies. Use the published no-sugar formula if you need that product.
Do pickled beets need a pressure canner? No. Once they are acidified with a tested brine, a boiling-water bath is correct. Pressure canning pickled beets is unnecessary and can overcook them.
The beets floated above the brine after processing. Are they safe? If the lid sealed and you followed a tested recipe and time, they are generally treated as safe. Quality is worse where slices sit dry. Refrigerate jars that lost most of their liquid.
How long before I can eat them? They are safe after they cool and seal. Flavor is better after several days.
Can I can golden or Chioggia beets the same way? Yes for the method, if you follow the same sizes and brine. Golden beets will not stain as hard. Candy-stripe varieties fade when cooked.
Water-bath canning beets is straightforward once the product is pickled. The method fails only when someone treats plain beets like pickles. Use vinegar in a tested amount, process the full time for your altitude, and keep plain beets for the pressure canner or the freezer.
