We have really tried everything - several wooden bread baskets, expensive plastic containers with or without membrane. But throughout our whole grain bread has become moldy. Then we tried this Römertopf. Since then more than 2 years, we are very happy with it. If the bread is really times longer in the pot and nothing happens, but I cleanse it, sometimes with vinegar water. Have him several times already packed in the dishwasher. No problem. For us, this is really the perfect bread storage. Would I buy again at any time !!! Pay me now two Roman pots set for baking bread and thus banish the plastic completely from the kitchen :-)
