Expert baking sites note its popularity among rye and whole-grain starter users. With nearly 2,000 reviews, it’s one of the most popular glass jars for sourdough starter in 2026.

- Thick soda-lime glass tolerates rapid temperature changes during fridge-to-counter transitions. (YouTube reviewer)

Cons

- Price per jar is higher than single-jar Weck options when you don’t need a pair. (https://homelybites.com/best-jar-for-sou)
Product Overview
The Weck 743 Mold Jar is repeatedly cited by expert sourdough educators as the most forgiving container for maintaining a healthy starter. Baking-focused sites such as The Perfect Loaf and Pantry Mama point to its straight walls and wide opening as key reasons starters stay cleaner and more stable over time. Reddit users echo this, frequently mentioning fewer mold incidents after switching from mason jars. YouTube bakers demonstrate how the 3/4‑liter capacity accommodates aggressive fermentation without constant overflow, making it a low-stress option for daily feeding routines.
This set includes two identical 743 jars, each holding roughly 750 ml, with thick glass walls and a 100 mm opening. Unlike threaded mason jars, the Weck system uses a resting glass lid and optional gasket, allowing natural gas release during fermentation. Expert guides note that this passive venting reduces pressure risks without drying out the starter. If you’re unsure why jar shape matters more than lid tightness, our buying guide below breaks down the mechanics in detail.
What Users SayWith a 4.8-star average from 482 Amazon reviews and consistently positive Reddit sentiment, user satisfaction is unusually high. Many reviews mention using the same jars for over two years without breakage or odor retention.WECK 743 Mold Jar - Sourdough Starter with Wide Mouth : In-Depth Analysis
In real-world use, YouTube reviewers feeding starters twice daily showed noticeably less starter climbing and crust formation compared to taller 1‑liter jars. Reddit users on r/SourdoughStarter report that switching to the 743 reduced cleaning time by several minutes per feed, adding up over months. While the glass lid must be left slightly ajar, most bakers consider this a feature rather than a flaw. The jar’s thermal stability also prevents cracking during fridge storage, a problem frequently reported with thinner glass jars.
At $27.99 for two jars, the 743 competes with single premium jars like the Weck Tulip 745 at $18.78. Value-focused Reddit threads generally consider the two-pack the better long-term buy, especially for bakers rotating jars during cleaning. If you’re deciding between sizes or shapes, our buying guide below explains how volume and wall angle affect fermentation behavior. For daily bakers, the durability and ease of cleaning offset the higher upfront cost.
Specifications
| Capacity | 0.75 liters per jar |
|---|---|
| Material | Soda-lime glass |
| Mouth Diameter | Approx. 100 mm |
| Included Lids | Glass lids with rubber gaskets |
| Dishwasher Safe | Yes |
| Set Size | 2 jars |
Final Verdict
The Weck 743 Mold Jar earns its Editor’s Choice by solving the problems that actually kill starters: dried residue, poor access, and overflow. Expert baking sites like The Perfect Loaf consistently recommend this exact shape, while Reddit users report fewer mold resets compared to tall mason jars. Compared to the Weck Tulip 1‑liter, the 743’s shorter profile is easier to manage during peak rise. At $27.99 for two, it’s not cheap, but long-term reliability and ease of use justify the premium for anyone baking weekly.

Pros
- Same fermentation-friendly shape as the Editor’s Choice Weck 743 with proven long-term starter stability. (Web Source)
- Lower upfront cost for bakers who only need one dedicated starter jar. (Web Source)
- Thick glass resists thermal shock during fridge storage. (YouTube reviewer)
Cons
- More expensive per jar than the two-pack version. (https://www.theperfectloaf.com/best-sour)
- No backup jar if cleaning overlaps with feeding time. (https://www.reddit.com/r/Frugal/comments)
Product Overview
The single Weck 743 Mold Jar offers the same fermentation-friendly design that expert sourdough sites routinely recommend. Guides from Kensington Sourdough and The Perfect Loaf emphasize that jar geometry, not branding, is what protects starters long term. Reddit users often recommend this version to beginners maintaining one starter. YouTube demonstrations confirm identical usability compared to the two-jar set.
Holding 750 ml, the jar accommodates typical 1:1:1 feed ratios without overflow. The wide mouth simplifies mixing and cleaning, and the glass lid allows passive gas release when rested loosely. Our buying guide below explains why this matters more than airtight seals for starters.
What Users SayA 4.8-star rating across 463 reviews reflects strong satisfaction, with minimal reports of breakage or defects.Weck Canning Jars 743 : In-Depth Analysis
User testing shared on YouTube shows consistent rise behavior and fewer dried rings compared to mason jars. Reddit bakers report predictable fermentation cycles and easier maintenance. The only recurring complaint is wishing they’d bought the two-pack initially.
At $17.98, it competes with larger 1‑liter jars like the Weck Tulip. If you’re unsure about size trade-offs, our buying guide below walks through volume considerations. Value-focused buyers often upgrade to the two-pack later.

|---|---|
| Material | Glass |
| Mouth Diameter | Approx. 100 mm |

Final Verdict
The single Weck 743 performs exactly like the two-pack version, using the same glass thickness, lid system, and 0.75‑liter capacity. Expert baking sites make no distinction in fermentation results between the two. However, Reddit value discussions consistently recommend the two-pack unless counter space is extremely limited. If you only need one jar, this is still an excellent choice—but not the best deal.
