Keep Fresh Post fermentation cap - Large
Use this cap with our Weck Fermenting Jars (both 1.5L and 2.5L) so you can remove the airlock and lid for easy storage in the fridge.
Weck Keep Fresh covers are BPA free and are suitable for storing opened jars of preserves in the fridge or when storing food in the freezer. As the lids expand slightly, there is a lower chance of glass breakage when food expands as it freezes.
The plastic covers also convert your jars into very handy storage containers. Also use to store herbs and spices, reorganise your pantry or carry juice in one of the stylish juice bottles.
