The different Weck jar capacities and their uses

Weck jars have been a kitchen essential for more than a century thanks to their strength, their many shapes and their durability. To meet every need, they are available in many different sizes, from the small 35 to 80 ml format, ideal for verrines, spices and condiments, to very large volumes from one to three litres, perfect for storing cereals, rice or pasta in bulk.

The most versatile jars are probably those with a medium capacity, between 200 and 600 ml. Depending on your preferences, they are very suitable for homemade jams, sauces, pickles, takeaway desserts, but also for charcuterie and catering preparations such as pâtés, rillettes or individual terrines.

Larger models, from 850 ml to 1 litre, are perfect for cooked dishes, soups or fruit in syrup. Finally, for large quantities of bulk food, it is better to choose large capacities, over 1 litre, which guarantee optimal storage in a fully airtight container.

Weck jars are also available in several shapes: cylindrical, tulip, rounded and more. They all come from different collections, such as Corolle, Fête or Quadro, whose base is square. Each of these models is made in the usual Weck jar capacities, making it possible to choose a glass jar according to both its capacity and its shape without compromising on either criterion. In addition, the accessories that are inseparable from these iconic glass jars, rubber seals and metal clips, are compatible with all models from the brand.

These multiple sizes and shapes contribute to the authentic charm and practicality of these iconic jars, which naturally find their place in the kitchen but also elsewhere in the home, sometimes serving as decorative objects.

How to choose the capacity of your Weck jars?

Every cook has their own favourite Weck jars! The choice of glass jars depends on their uses, but also on the possible preservation method. Before making a decision, it is recommended to think about the type of food to store and the quantity required.

Mini formats, from 80 to 160 ml, are ideal for preparing verrines, individual desserts, cold starters or gourmet gifts.

For homemade jams, chutneys or jellies, small formats, from 100 to 290 ml, may be sufficient. These quantities are consumed quickly and help limit food waste.

To preserve cooked dishes, soups, family recipes or fruit in syrup, which take up more space, it is better to choose larger capacities, such as 850 ml to 1 litre jars. Models with a capacity over one litre are more suitable for fermentation and large homemade preserves, or simply for storing dry bulk groceries.

In addition to considering the type of food to be preserved, it is also important to take into account the space available in the kitchen or pantry. In the refrigerator, several small jars offer more flexibility than a single large one, for example. If you are planning storage in a cupboard, priority can be given to stackable models.

The type of lid also plays an important role in choosing a jar: plastic freshness lids are mainly intended for chilled storage, short-term preservation and transport after opening, while traditional glass lids with seals and clips are designed for safe sterilisation, pasteurisation or fermentation.
