Premium Sourdough Starter and Dough Proofing Set, 2-Piece Borosilicate Glass Containers with Airtight Lids, Wide Mouth Measuring Bowls (24oz and 71oz) Review (2026)

Who this set fits

This is a two piece glass container set aimed at sourdough bakers who want a dedicated jar for feeding and storing a starter alongside a larger bowl for bulk fermenting or proofing dough. The 24oz container suits typical starter volumes for a home baker who feeds once or twice a day, while the 71oz bowl gives enough room for a single loaf's worth of dough to rise with headroom to spare. It fits someone who currently uses mismatched jars and bowls and wants a matched glass set with markings for measuring, rather than someone managing several loaves worth of dough at once, where the 71oz bowl may run out of room.

Materials and design explained

Both containers are made from borosilicate glass, a material valued for resisting temperature shock better than standard glass, and the listing states the containers are safe for the microwave, oven with the lid removed, refrigerator and dishwasher. Each container has a wide mouth opening, which makes feeding a starter, stirring in flour, or scraping out risen dough easier than a narrow necked jar. The lids are airtight with a BPA free seal, aimed at keeping contents fresh in storage, and both containers include measuring markings on the side to track how much a starter or dough has grown. Wide mouth openings on both pieces also make washing by hand or in a dishwasher simpler than jars with narrow necks.

Living with the set day to day

In daily starter care, the 24oz jar works well for storing a fed starter in the refrigerator between bakes, since the wide mouth makes stirring in fresh flour and water simple, and the measuring lines help gauge how much it has risen since the last feed. Because the lid is airtight rather than vented, an actively growing starter left at room temperature can build pressure, so it helps to loosen the lid slightly or use a looser fitting lid during an active rise rather than sealing it completely, as a fully airtight lid on a bubbling starter is more prone to bulging or popping open. The 71oz bowl handles bulk fermentation for a single loaf comfortably, with enough headroom for the dough to roughly double, though bakers doing large batch or multi loaf bakes will find its capacity limiting.

How it compares with other glass starter jars

Against the Brod and Taylor Sourdough Starter Jar, which uses a loose fitting lid designed specifically to vent gas from an active starter, this set's airtight lids are better suited to storage than to housing a starter through its most active rise. Compared with the BREADLING starter jar kits, which pair a large jar with a smaller airtight storage jar plus cloth and bands, this set instead pairs a starter sized jar with a much larger proofing bowl, better suiting bakers who want one container for dough as well as starter rather than starter focused accessories like cloth covers.

Verdict for sourdough bakers

This set suits a baker who wants one purchase to cover both starter storage and dough proofing in matched, oven safe glass, and who is comfortable loosening the lid during an active starter rise rather than relying on a vented design. It is a lesser fit for anyone baking multiple loaves at once, where the 71oz bowl may prove too small, or for a baker who specifically wants a lid engineered to vent starter gas automatically, where a jar built for that purpose is the safer choice. The measuring markings on both pieces are a nice touch for tracking rise over time.
