Ball vs Kerr: Which Brand is Better?

Ball and Kerr jars are essentially the same product. Both brands are owned by Newell Brands, manufactured in the same facilities, to the same specifications. The only real differences are price and branding, Kerr jars typically cost less while Ball enjoys stronger brand recognition.

Feature	Ball	Kerr
Manufacturer	Newell Brands (USA)	Newell Brands (USA)
Quality	Industry standard	Identical to Ball
Price	Higher (brand premium)	Lower (better value)
Availability	Very widespread	Widely available
Lids	Interchangeable	Interchangeable
USDA Approved	Yes	Yes

My recommendation: buy whichever is cheaper. Ball and Kerr lids are completely interchangeable, the jars are identical in quality, and both are USDA-approved for safe canning. The only reason to prefer one over the other is if one brand happens to be on sale when you’re shopping.

Understanding Canning Jar Safety

Canning jars work by creating a vacuum seal during heat processing. When heated, air escapes from the jar. As it cools, the lid seals tightly, preventing bacteria and spoilage. The two-piece metal lid system is the most common, while European styles use glass lids with rubber gaskets and clips.

Quality canning jars are essential for food safety because USDA-approved jars prevent botulism and other foodborne illnesses by maintaining proper seals during processing. Cheap or improper jars can break or fail to seal, risking food contamination and spoilage. The National Center for Home Food Preservation recommends only using jars specifically manufactured for home canning.

How to Choose the Best Canning Jars

Choosing the right canning jars depends on your intended use, canning method, and budget. After testing dozens of jar types over the years, I’ve developed a simple framework for selecting the perfect jar for any project.

Step 1: Determine Your Canning Method

Water bath canning works with both regular and wide mouth jars, but wide mouth is generally easier for filling and cleaning. Pressure canning requires jars specifically rated for pressure use, which all Ball and Kerr mason jars are. Fermentation works best with wide mouth jars for easy access and some air exchange.

Step 2: Choose the Right Size

Size	Capacity	Best For
Half Pint (8 oz)	237 ml	Jams, jellies, gifts, small portions
Pint (16 oz)	473 ml	Salsas, sauces, leftovers, meal prep
Quart (32 oz)	946 ml	Pickles, fruits, pressure canning, storage
Half Gallon (64 oz)	1.9 L	Dry goods, large batches, cold brew

Step 3: Select Mouth Type

Wide mouth jars are easier to fill and clean, better for whole foods, and more versatile overall. Regular mouth jars are better for liquids, have a tapered neck that helps with sealing, and are often slightly cheaper. For most beginners, I recommend starting with wide mouth jars for their versatility.

Step 4: Pick Your Brand

Ball and Kerr are the safe, reliable choices for most canners. They’re USDA-approved, widely available, and competitively priced. Weck offers premium European design for aesthetic-focused users. Le Parfait provides excellent sealing for specialized needs. Store brands like Mainstays should be avoided due to quality concerns.

Step 5: Calculate Quantity

Buy more jars than you think you’ll need. Canning season always brings unexpected harvests and opportunities to preserve. Having extra jars on hand means you’ll never have to pass up fresh produce or turn down gift-giving opportunities. I recommend buying at least 20% more than your estimated need.
