Rakovar R-WQJar2 50oz Sourdough Starter Jar Set, Wide-Mouth Glass, 2-Pack

For home bakers who want room to maintain a sourdough starter and keep a second batch or jar in rotation, the Rakovar R-WQJar2 set includes two 50oz glass jars.

Each jar has a wide opening for adding flour and water, stirring, and reaching the sides when cleaning. Clear glass, measurement markings, and adjustable feeding bands help you track the starter’s level after feeding.

The kit also includes wooden lids, cloth covers, thermometers, and silicone spatulas. That gives you several starter-care tools in one set, rather than a single jar with fewer accessories.

What stands out

The two-jar format gives you options: keep one jar for an active starter and use the other for a split batch or a separate stage of your routine. That flexibility may be useful when preparing for baking or maintaining more than one batch. Each jar holds 50oz, and the product description says the extra room allows starter to expand after feeding.

The wide mouth is a practical detail for everyday feeding. It gives you space to stir and scrape the sides, while the transparent glass and markings make it easier to see and mark a rise. These features support visual monitoring, they do not guarantee a particular rise or baking result.

Buyer feedback is positive about the jars’ capacity, ease of cleaning, and included accessories. Opinions differ on the glass thickness and how well the lids seal, so treat the lids as part of the included kit rather than assuming they provide a consistently tight seal.

Quick overview

This is a two-piece sourdough starter jar set made from clear borosilicate glass. Each jar has a 50oz capacity, a wide mouth, measurement markings, and an adjustable feeding band. The package also includes wooden lids, cloth covers, thermometers, and silicone spatulas. The listed dimensions are 5 x 3 x 5 inches, and the listed weight is 1 pound.

The contents suit a routine that involves feeding, observing, and maintaining starter in jars. If you already have a preferred thermometer or spatula, the value of the included tools may matter less, the main distinction from buying one basic jar is the second vessel and the added accessories.

Best use cases

Use the pair to keep an active starter separate from a second batch, or to have another jar available when splitting or managing starter at different stages. For example, a home baker preparing for a baking session could keep one jar in their regular routine and use the other to hold a separate portion. The markings and bands help show a starting level and make changes easier to observe.

It suits you if you want two roomy jars and useful feeding accessories in one set. It might not be a great match if a consistently tight-sealing lid is essential: buyer feedback on lid sealing is mixed, and reports also differ on perceived glass thickness.

Before you decide

What comes with the jars? The set includes two glass jars, wooden lids, cloth covers, adjustable feeding bands, thermometers, and silicone spatulas.

How can you track starter activity? The jars are transparent and have measurement markings, adjustable bands can mark the starting level so you can see how far the starter rises after feeding.

Are the lids reported to seal reliably? Buyers have mixed experiences. Some like the seal, while others say the lids do not seal effectively, so the feedback does not establish a consistent sealing result.

When it makes sense

Choose this set if having two 50oz jars is useful to your starter routine and you want the feeding bands and other listed tools included. A single basic jar may be enough if you only need one vessel and already have the accessories. If you choose this set, base your decision on its capacity, wide-mouth design, and two-jar flexibility—not on an assumed airtight seal.
