Sauerkraut Equipment Guide: From Basic to Advanced
Good news: you probably already own what you need to make sauerkraut. At minimum, you need:
- A container - glass jar, ceramic crock, or food-safe bucket
- A weight - anything to keep cabbage submerged
- A cover - cloth, plate, or airlock lid
- A knife - for slicing cabbage
- A scale - for measuring salt accurately
That's it. Everything else is optional convenience.
Start Simple
Don't buy expensive equipment until you know you love fermenting. A mason jar and plastic bag weight work perfectly well for learning.
Fermentation Vessels
Mason Jars ($)
- Pros: Cheap, available everywhere, easy to see progress
- Cons: Small batches, need separate weights
- Best for: Beginners, small households
Wide-Mouth Jars with Airlock Lids ($$)
- Pros: Hands-off fermentation, no burping needed
- Cons: More expensive, lids need replacement
- Best for: Regular fermenters who want convenience
Fermentation Crocks ($$$)
- Pros: Large batches, traditional method, excellent insulation
- Cons: Heavy, expensive, can't see inside
- Best for: Serious fermenters, large families
Food-Grade Buckets ($)
- Pros: Very large batches, cheap
- Cons: Not pretty, harder to weight properly
- Best for: Large-scale production, restaurants
Avoid Reactive Metals
Never use aluminum, copper, or cast iron for fermenting. The acid reacts with these metals. Stick to glass, ceramic, food-grade plastic, or stainless steel.
Fermentation Weights
DIY Options (Free)
- Zip-lock bag filled with brine
- Clean rock or river stone
- Small plate or bowl
Glass Weights ($)
- Fit inside mason jars
- Easy to clean
- Various sizes available
Ceramic Crescent Weights ($$)
- Traditional design
- Work with crocks and wide jars
- Heavy and effective
Spring-Loaded Weights ($$)
- Push-down mechanism
- Integrated with some lids
- Very hands-off
The Key Rule: Whatever you use, it must:
- Keep ALL cabbage below the brine
- Be food-safe (non-reactive)
- Be heavy enough to stay in place
Lids and Covers
Cloth Cover (Free)
- Pros: Allows gas escape, traditional
- Cons: Must weight, higher contamination risk
- How: Cheesecloth or clean towel + rubber band
Regular Jar Lid ($)
- Pros: Tight seal, always available
- Cons: Must "burp" daily to release CO2
- How: Screw on loosely or open briefly each day
Airlock Lids ($$)
- Pros: One-way valve, no burping, reduced contamination
- Cons: Cost, need batteries for some
- Options: Simple airlocks, silicone seals, electronic monitors
Water-Seal Crocks ($$$)
- Pros: Traditional, excellent seal, very hands-off
- Cons: Expensive, heavy, large batches only
- How: Water in rim creates perfect one-way seal
Cutting and Preparation Tools
For Slicing Cabbage:
- Sharp knife - free if you own one
- Mandoline ($) - consistent thin slices, faster
- Food processor ($$$) - fastest, can be too fine
For Mixing and Packing:
- Large mixing bowl (essential)
- Wooden tamper/pounder ($) - easier packing
- Cabbage shredder ($$) - traditional German tool
For Measuring:
- Kitchen scale (essential) - digital preferred, $10-20
- Measuring spoons - for small amounts of salt

Intermediate Setup ($40-60)
- Half-gallon wide-mouth jar
- Glass fermentation weights
- Airlock lid
- Kitchen scale
Serious Fermenter ($100+)
- 5L+ fermentation crock with water seal
- Multiple jar sizes with airlock lids
- Quality mandoline
- Wooden tamper
- pH strips or meter
Frequently Asked Questions
Do I really need an airlock lid? No. Airlock lids are convenient but not necessary. A loose-fitting regular lid (burped daily) or cloth cover works fine. Many traditional fermenters never use airlocks.
Can I use a regular jar with a regular lid? Yes, but you must "burp" it daily by briefly opening to release CO2, or leave the lid loose. Don't seal it tight or pressure could build up.
What size jar should I start with? A quart (1L) jar is perfect for beginners. One small cabbage makes about a quart of sauerkraut. Once you're comfortable, scale up to half-gallon or larger.
Is a fermentation crock worth the investment? If you make sauerkraut regularly and want to do large batches, yes. The water-seal design is excellent. For occasional small batches, jars are more practical.
