BREADLING Wide Mouth Glass Sourdough Starter Jar Kit Teal, 32 oz Large Glass Jar with Lid, 8oz Airtight Storage Jar, Muslin Cloth, Bands and Dry Erase Pen Review (2026)

Two Jars, Two Jobs

This teal kit pairs a 32 oz wide mouth glass jar for the active starter with a smaller 8 oz airtight jar meant for storage, such as holding back discard or keeping a dormant backup culture in the fridge. That second jar solves a real annoyance in sourdough baking, since discard needs somewhere to live between the moment you scrape it out and the moment you use it in a recipe or the trash. Both jars are round with a wide mouth opening, which the maker notes is designed for easy cleaning, and both are listed as dishwasher safe including the lids, a convenience that not every glass starter jar offers given how sourdough residue can dry onto glass.

Cloth Cover and Bands

Alongside the two jars, the kit includes a muslin cloth cover with two bands, meant to sit over the jar mouth during active fermentation so the starter can breathe while staying protected from dust and stray flour in the air. This is a useful alternative to a solid lid during the feeding and rise stage, when trapping gas under an airtight lid can build pressure or slow visible rise cues. The included dry erase pen is a small but practical extra, letting you write the feeding time or a note directly on the glass jar rather than relying on a separate log or app, and it wipes off cleanly for the next note.

Lids and Fridge Storage

Both jar lids are described as textured and rubberized for grip, and the maker states they hermetically seal, which matters when moving a starter to the refrigerator between baking sessions to slow fermentation. The maker also lists both jars as freezer safe, useful if you want to pause a starter for a longer stretch rather than feeding it daily. For most home bakers the main jar spends its active life uncovered or under the cloth cover, with the sealing lid reserved for storage stretches, so the seal quality mainly matters during those pauses rather than day to day feeding.

Everyday Fit

The 32 oz size gives a fed starter room to roughly double without overflowing, which covers typical single loaf home baking without needing to feed unusually small portions to stay inside the jar. Bakers who build large levains for multiple loaves at once, or who like to keep a very active, fast rising starter, may find 32 oz on the smaller side and outgrow it faster than a 40 oz or larger jar. The included recipe access mentioned by the maker gives a starting point for a no fail starter, which is a helpful nudge for someone setting up their first jar rather than transferring an existing culture.

Care and Value

Because both jars and lids are listed as dishwasher safe, cleanup is less of a chore than with jars that require hand washing only, which matters given how often a starter jar gets cleaned during active feeding cycles. The muslin cloth will need its own occasional wash since it sits against the jar mouth and picks up flour dust over time. BREADLING backs the kit with a satisfaction guarantee according to the listing. Buying the color variant mainly comes down to kitchen preference, since the jars, lids, cloth, bands and pen are the same across the color range this kit is sold in.
