Sauerkraut the old school way. We shred fresh cabbage with our high grade salt and let the little guys do the rest. Great with so many things we lost track...let us know your strangest or favorite use for the all American original. The quarterback of kraut! Important: There may be some leakage of juices during shipping in summer weather. This is due to the probiotic bacteria waking up and releasing some CO2. The lids are designed to allow some venting when needed rather than have the glass break from the built up pressure. If this happens the product is absolutely safe as the pressure only allows a one way movement, nothing comes in. Upon arrival we suggest to slightly turn the lid over a sink to vent any CO2 and then refrigerate. We can not accept returns or refund in these circumstances, so please do not order this listing if it is a concern. We work closely with Pickled Planet, and they have given approval for shipping this item unrefrigerated. We store these products cold in our warehouse at all times and they need to be refrigerated upon receipt. This product can be sent unrefrigerated because it takes many days for the live cultures to wake up and restart the process of fermentation (which could alter the product taste). We do this to help save you shipping costs, since shipping products cold would require a cooler and gel packs, and 3 day travel zones might even require sending via air to guarantee they arrive cold. We only ship on a date that will allow the product to get to you within a week. If you have any questions or concerns, please feel free to contact us prior to placing your order. We can not accept returns for this product because it arrives at room temperature, this is why we are letting you know the policy herein.
