Le Parfait Super Terrine French Glass Jars (32oz Quart, Pack of 4)

The French Canning Jar That Has Stayed Plastic-Free Since 1930

Le Parfait jars are the iconic French preserving jars you have seen holding jam at a farmers market or pickles in a country kitchen, and they have been made in France since 1930.

This set is four 32-ounce (1-liter, quart) Super Terrine jars, and what makes them belong in a microplastic-free kitchen is the construction: a glass jar, a glass lid, a natural rubber gasket, and a stainless steel wire bail that clamps the lid down. There is no plastic anywhere in the sealing system, your food sits against glass and the seal is natural rubber, which is exactly the combination to look for in a sealing jar.

The wide-mouth, slightly tapered body makes it easy to fill, scoop from, and turn out contents, and the spring-loaded bail gives you a visual check that the vacuum seal took after canning. These are genuine canning jars, rated for water-bath canning and fermentation, so they handle pickles, sauerkraut, kombucha, jams, and sauces as readily as they store dry pantry goods like flour, coffee, rice, and beans. Made from BPA-free, lead-free French glass, they are dishwasher safe, freezer safe, and built to be reused for decades rather than thrown away.

True Shift Score: 8.5 / 10

This is our own assessment, not a lab result or a certification.

It scores high for a genuinely plastic-free sealing system, glass jar, glass lid, natural rubber gasket, and stainless wire bail, in a made-in-France canning classic that is built to be reused for generations, all in a good-value four-pack. It sits just below the all-glass options on our material-purity scale because the rubber gasket is a consumable that needs hand washing and periodic replacement, which is the normal upkeep of a traditional preserving jar rather than a shortcoming. For plastic-free canning and preserving, it is an excellent choice.

The Honest Tradeoffs

The natural rubber gasket is the part to understand.

1. It is what makes the seal plastic-free, and it is a consumable: for actual water-bath canning, the gasket should be replaced each cycle to guarantee a safe seal, and even for everyday storage the rubber softens over time and is eventually replaced, which Le Parfait sells separately. 

2. Hand wash the gasket without detergent, and avoid letting it sit against pure fats. 

3. The wire bail also benefits from occasional care, rotating the ring now and then spreads the clamping wear so the same spot on the glass rim is not stressed repeatedly. 

4. None of this is a flaw, it is simply how a traditional rubber-and-wire sealing jar works, and it is the trade for a genuinely plastic-free seal.

How We Evaluate Food Storage

We look at four things, and none is a lab score:

1. Whether the food-contact surface is inert and won't leach

2. Stain, or hold odors, what the lid is actually made of, since that is where plastic hides in most "glass" storage

3. How well it seals and holds up across the fridge, freezer, microwave, and dishwasher, 

4. And how durable it is over years of use. 

The real shift in food storage is getting your food off plastic and onto glass.
