If you are using one of the Weck fermenting jars, choose small for the 1-litre jars and medium for the 1.5-litre jars.
If you are using the Ball 2-litre jars or Fido jars you can use the small weight but due to the width of the shoulders there will not be full coverage of the surface. In this instance, you can use vegetables such as cabbage leaves or strips of carrot peel to cover the surface and then weigh this with a small weight.
Note the fit is tight and if you are fermenting very liquid foods, the weight will sink unless there is sufficient food mass in the jar to hold it up.
Scratches, divots, cooling swirls and other small imperfections are completely normal and can appear on the surface of the jars and glass lids. All glass jars and lids are submitted to an electronic eye that will detect serious flaws.
