2-Pack Sourdough Starter Jar Kit — 50oz & 34oz Wide-Mouth Glass

2-Pack Sourdough Starter Jar Kit — 50oz & 34oz Wide-Mouth Glass

Product description

Dual-size borosilicate glass jars: This kit contains two clear, premium borosilicate glass vessels — a larger 50oz jar and a smaller 34oz jar — suited to different starter volumes and batch needs. The glass is formulated to tolerate temperature changes, so moving a jar between the fridge and countertop won’t easily cause cracks, making them suitable for daily feedings and ongoing starter maintenance.

Wide mouth and anti-slip base: Each jar has an extra-wide opening to make stirring, pouring and deep cleaning simple and spill-free. Two silicone anti-slip pads are fitted to the base area to stabilize the jars during mixing and prevent unwanted sliding or toppling on slick surfaces.

Dual fermentation options and feeding tracker: You can alternate fermentation modes by swapping covers — a bamboo lid creates an airtight environment for slower, chilled fermentation, while a breathable cloth cover speeds up activity on the counter. An elastic date-marking band is supplied so you can record feed times, and a stick-on jar thermometer helps you monitor ambient starter temperature for healthier fermentation.

All-in-one accessory set: The package includes two bamboo lids, two breathable cloth covers, two date tracker bands, two thermometers, two silicone mats, one silicone scraper, one baking spoon and one graduated measuring cup. The jars have molded scale marks so you can eyeball starter volume and track feedings without extra tools.

Practical countertop style and gift option: The clear glass paired with natural bamboo lids offers a simple, rustic look that complements kitchen decor. Because it bundles feeding and measuring tools, the kit is suitable as a present for friends or family starting with sourdough baking.

Care guidance: The glass components are dishwasher-safe, but hand washing is recommended once the temperature-sensitive sticker has been applied to prolong the life and accuracy of the thermometer indicator.

Pros

  • Two jar sizes for different batch needs
  • Wide mouths and anti-slip pads for easy handling
  • Comprehensive set of feeding and measuring tools

Cons

  • Temperature sticker is delicate — hand wash advised
  • One-piece airtight seal may not prevent all drying issues
  • Potential for damage during shipping

VerdictA complete, well-made starter kit for home bakers who want two jar sizes and clear feeding tools. The glass, lids, and accessories support both slow refrigerated storage and active on-counter fermentation, though a damaged shipping item or inconsistent airtight seal can be problematic for some users.

Reviews

  1. Sarah 1/5

    Didn’t protect my starter

    Even with the wooden lid on one jar my starter dried out, and the other jar developed mold after a few days in the refrigerator.

  2. Weego 5/5

    Solid value set

    A very nice collection of tools and jars for getting started without missing essentials.

  3. Kaitlyne L 5/5

    A noticeable step up from mason jars

    These replaced my old mason jars and are much more convenient. The temperature sticker and printed volume marks make monitoring simple. They include a fabric cover for active fermentation and a wooden lid for cold storage. I also like how easy it is to see when the starter has doubled.

  4. EB 5/5

    Complete starter set that feels durable

    The two jar sizes are perfect for different batch levels and the borosilicate glass feels sturdy. They tolerate fridge-to-counter temperature changes without cracking, which simplifies regular feedings. The wide mouths make mixing and cleaning effortless, and the silicone feet keep the jars from sliding. Everything you need is included — lids, covers, thermometers, date bands, silicone mats, a scraper, spoon and measuring cup — and the scale marks and tracker help keep feedings organized. They look nice on the counter and make a thoughtful gift.

  5. Sassy22WA 5/5

    Really pleased with the upgrade

    Much better than other options I’ve tried. They’re attractive, simple to clean, and work as intended.

  6. ConnieLFlorida 2/5

    One arrived damaged

    The larger jar was fine but the smaller one I wanted most arrived broken. The box was marked fragile but the outer shipping box covered it. I contacted customer service and requested a refund, though the original listing indicated no returns.

  7. JP 5/5

    Finally ready to commit to sourdough

    This all-in-one kit gave me the confidence to start a regular routine. The dual-size heat-resistant jars let me run a small or larger starter depending on my baking plans. I especially appreciate the very wide openings for easy feeding and the variety of accessories that keep me organized while learning the process.
