Weck 766 Juice Jar

Yes, the Weck 766 uses a classic glass lid paired with a rubber sealing gasket and metal clips to create a reliable, airtight seal. While it is excellent for upright storage in the fridge, we recommend keeping it upright rather than on its side to ensure no leakage.

Absolutely. Weck jars are designed specifically for traditional canning methods. The glass lid, rubber gasket, and metal clips are engineered to withstand the heat processing required for preserving fruits, juices, and pickles.

The glass jar and lid are dishwasher safe. However, the rubber gasket should be hand-washed to maintain its elasticity and ensure a proper seal for future uses.

The opening is wide enough to accommodate a standard bottle brush, which is the most effective way to clean the interior. If you have large hands, you may find it difficult to reach the bottom directly, so a long-handled brush is recommended.

We do not recommend using this jar in the freezer. Rapid temperature changes can cause the glass to crack, and the expansion of frozen liquids often leads to breakage.
