French Glass Canning & Food Preserving Jars

Le Parfait preserving jars are designed as working kitchen vessels, not disposable containers. The glass is made in France, the closure systems are matched to specific jar families, and the sealing components can be replaced when needed so the jar can return to service.

Super Jars and Super Terrines pair a hinged glass lid with a fresh orange rubber seal and stainless-steel wire frame. Familia Wiss Terrines use a flat sealing cap beneath a reusable screw band. Bistrot Jars use a removable clip, glass lid and compatible rubber seal. Jam Jars use a pasteurizable metal twist lid for fruit preserves.

For every heat-processing project, confirm the jar family, use the correct fresh sealing component and follow the approved recipe and processing instructions. After the project is complete, inspect the glass and closure before returning the jar to storage or another kitchen use.

Water-bath canning is used for approved high-acid foods such as jams, jellies, marmalades, fruit in syrup, pickles, chutneys, salsas and properly acidified tomato recipes. During processing, filled jars are heated according to the recipe, allowing the closure to form its seal as the jars cool.

Super Jars, Super Terrines, Familia Wiss Terrines, Bistrot Jars and Jam Jars may be used for approved Le Parfait water-bath preserving projects when paired with the correct closure and fresh sealing component. Match the jar size to the recipe, leave the specified headspace and adjust the processing schedule for elevation when directed.

For low-acid foods, including plain vegetables, meats and many broths, follow the exact method provided by the approved recipe. Many low-acid recipes require pressure canning; do not substitute a general water-bath process unless the recipe has been specifically formulated and approved for that method.

Jam has its own Le Parfait traditions. Jam Jars are designed for jams, jellies, marmalades, fruit curds and other fruit preserves, using a fresh compatible twist lid and the approved method for the recipe. Le Parfait America also supports the brand-approved inversion method for compatible Jam Jar recipes: the hot preserve is filled into the prepared jar, capped and inverted according to the complete recipe instructions so the heat of the preserve helps set the closure.

Jam Pots offer a different experience. Their vintage working-glass shape and reusable snap covers make them especially well suited to refrigerator jams, honey, curds, condiments, breakfast service, gifting and small portions. They also evoke the traditional French presentation of homemade conserves, including heritage methods once finished with a waxed surface. Today they are best used for refrigerator preserves, serving and gifting.

Preservation does not always require heat processing. Quick pickling uses vinegar and refrigeration to create crisp, tangy vegetables for everyday meals, while salt-based fermentation transforms ingredients through naturally active cultures.

Le Parfait glass does not absorb flavors or odors and makes it easy to monitor brine level, bubbles and changes in the ferment. Use compatible jars for sauerkraut, kimchi, preserved lemons and other approved recipes, keeping ingredients submerged and following the recipe’s salt, temperature and timing guidance.

For a fast place to begin, try Quick-Pickled Red Onions. For fermentation equipment, compatible jars and guided recipes, explore The Little Fermenter and the Fermentation collection.

Drying preserves food only when the finished ingredients remain protected from returning humidity. Once herbs, mushrooms, fruit, vegetables or other foods are fully dehydrated and conditioned, transfer them to clean, dry jars with compatible closures.

A well-closed glass jar helps protect dried foods from humidity, odors and pantry pests. Clear glass also makes it easier to watch for condensation or other signs that additional drying may be needed. Label each batch with the ingredient and date, and store it according to the recipe or dehydration guide.

For everyday flour, grains, pasta, coffee and bulk pantry organization, continue to the Storage collection.

Begin with the preserving method, then choose the jar. Water-bath recipes require a compatible heat-processing jar and closure. Fermentation depends on headspace, brine coverage and the equipment used. Refrigerator pickles and preserves may use closures designed for cold storage. Dried foods need a clean, dry jar that closes securely.

Capacity matters, but it is not the only consideration. Smaller jars are convenient for jams, condiments, relishes and sauces. Medium and larger jars suit pickled vegetables, whole fruit, fermentation and batch storage when the approved recipe supports that size. For broth and other low-acid foods, follow the exact jar size, closure and processing method stated in the approved recipe; many low-acid recipes require pressure canning.

Use the Jar Size Guide to compare capacities, shapes, openings and closure systems, and keep fresh replacement seals or caps ready for the next preserving project.
