Sourdough Storage Era-Weck Canning Jars
I've been using Weck canning jars to store my sourdough starter, and I couldn’t be happier. These jars are not only aesthetically pleasing with their vintage-style glass and glass lid, but they’re also incredibly functional for fermentation and long-term starter maintenance.The wide-mouth design makes feeding and stirring the starter super easy, and cleanup is a breeze. I especially appreciate the non-metal lids, which means no rusting or reactive materials in contact with the acidic starter—something that’s really important for maintaining a healthy culture.They seal well with the rubber gasket and clips, but for sourdough, I usually just place the glass lid on top without sealing it to allow gases to escape. The clear glass also makes it easy to monitor bubbles, rise activity, and hooch levels—so helpful for bakers who like to keep a close eye on their starter.They're durable, dishwasher safe, and look great sitting on the kitchen counter or in the fridge. Whether you’re new to sourdough or a seasoned baker, Weck jars are a stylish and practical upgrade from standard containers.

Great!
Love this jar! Easy to clean, and works so great for my sourdough starter! I like that it is wide enough that you are able to stir, and also there is no mess when dumping in the flour!

Beautiful Jar
I ordered this for sourdough starter and I love the jar! However, the rubber gasket for the lid is very difficult to keep in place. Not sure how well it would hold up if you wanted it to seal. I’ve stopped using the lid because I’m tired of fighting with it, but overall a very nice jar with no curves so good for starter.
