How to care for your Weck Jars

Weck jars are a great way to store and preserve food. But like any other type of container, they need to be properly cared for in order to stay in good condition.

Here are some tips on how to care for your Weck jars:

1. Wash the jars with warm soapy water before using them. This will remove any dust or dirt that may have accumulated on the jars.
2. Fill the jars with food items that have been properly processed. This includes canning, pickling, or freezing the food items.
3. Make sure the lids are tight and sealed before storing the jars. This will prevent air from getting into the jars and causing the food to spoil.
4. Store the jars in a cool, dark place. Weck jars are not meant to be stored in direct sunlight or in temperatures that exceed 100 degrees Fahrenheit.
5. Inspect the jars periodically for any signs of damage, such as cracks or chips. If you see any damage, discard the jar immediately.

Bonus: Can I freeze my Weck Jars?

Freezing items in a glass container is an excellent way to keep foods air tight and for a long time.

However, we recommend that you use only the Mold shape jars along with the plastic “Keep Fresh Covers” for freezing. The Keep Fresh Covers will allow for expansion and contraction. We do not recommend freezing in any of the other shaped jars (Juice, Cylindrical, Deco, Tulip, Deli). Do not use the glass lid, ring, and clamps to freeze in jars.

When glass jars are used for freezing, all basic freezing principles apply. In particular:

1. Leave proper headspace to avoid breakage, 1 – 1 1/2″. Food expand when the freeze, so headspace is very important.
2. Avoid extreme changes in temperature. Hot foods, such as soups, should be cooled before putting jars into the freezer and frozen foods should not be put directly into the microwave or hot water as this may cause the jar to crack. In order to avoid “thermal shock”, the temperature between the glass and the operating ambient temperature should not exceed a maximum of 50 degrees Celsius.

Weck jars are a great way to store food items for long periods of time.

By following these simple tips, you can ensure that your Weck jars will last for many years to come!
