Glass Sourdough Starter Jar 2 Pack, 24 oz Wide Mouth Organic Sourdough Starter Kit with Date Marked Band, Thermometer, Cloth Cover and Metal Lid, Reusable Bread Baking Supplies Review (2026)

Who benefits from a 2 jar setup

Keeping two jars going at once is genuinely useful insurance in sourdough baking, since starters can go through slow patches or pick up unwanted mold if neglected, and having a second jar means you are never starting completely from scratch if one culture fails. This kit suits that exact use case: one jar as your main starter and a second as either a backup fed on the same schedule or a separate culture, like a whole wheat or rye starter kept apart from your white flour one. The 24oz size per jar is described by the manufacturer as enough starter for around three loaves of bread, which is a workable amount for a household baking once or twice a week without filling the fridge with excess jars.

Jar design and what ships in the box

Each of the two jars is 24oz and wide mouth glass, which makes feeding and scraping easier than a narrow-necked jar, and the kit includes a date marked feeding band for tracking schedules, a thermometer, a cotton cloth cover with an elastic band for active fermentation, and a metal lid for sealed storage. The manufacturer notes the aluminum lid keeps the jar airtight enough to hold a starter in the refrigerator for a week or longer between feedings, which is handy for bakers who do not want to feed daily. Being marketed as multipurpose glass jars also means they can pull double duty for pantry storage of rice, coffee or other dry goods if you ever stop actively maintaining a starter in one of them.

Using the cloth cover versus the metal lid

The cotton cloth cover with its elastic band is meant for the active feeding stage, letting the starter breathe and keeping dust and stray insects out while gas escapes naturally, and switching to the metal lid is better reserved for refrigerated storage between bakes rather than while a starter is actively bubbling at room temperature. This two-lid system mirrors what most experienced sourdough bakers do anyway, alternating between a breathable cover during frequent feeding and a tighter seal when the starter goes into the fridge to slow down, so having both included saves you from buying a separate breathable cover.

How the 2 pack compares with single-jar kits

Against the single 24oz jar from the DWTS listing that includes a silicone scraper, this Mfacoy 2 pack gives up that scraper but adds the second jar for backup or a separate culture, which is the more valuable trade-off for most bakers past their first few months of sourdough. Compared with the 34oz ANPHSIN two-jar kit, this pack's 24oz jars take up less fridge space but hold noticeably less starter per jar, so bakers who bake multiple loaves in one session should lean toward the larger 34oz option instead, while anyone tight on fridge shelf space may prefer staying with 24oz.

Bottom line and who should look elsewhere

For the common sourdough habit of keeping a backup jar or a second culture on hand, this 2 pack hits a practical size and includes the tracking tools most beginners need, matching its strong marks for fit and value. Bakers who only ever run one starter and do not want a spare jar taking up space would do better with a single-jar kit, and anyone baking in larger batches regularly should look at 34oz or bigger jars instead of this 24oz pack, since two smaller jars will not match one big levain's capacity.
