2 Pack Large Fermentation Jars Review – 1.5 Gallon Glass Jars Tested

Quick Verdict

If you're hunting for large fermentation jars that can handle big batches of sauerkraut, kimchi, or kombucha without cramping your style, the Sovietiep 1.5 gallon set earns a solid place on your counter. After six weeks of real ferments — including one enthusiastic cabbage experiment that overflowed my old jar — these held up well. I rate them 4.2 out of 5. They're not the most premium-feeling jars on the market, but the value-to-capacity ratio is genuinely hard to beat.

What Is the Sovietiep 2 Pack Large Fermentation Jars?

The Sovietiep fermentation kit is a two-jar set built around 1.5 gallon (roughly 5.7 liter) glass vessels with wide 4.3-inch mouths. Each jar ships with an airtight lid and either one or two airlocks depending on the bundle, plus a small manual. The brand positions these as all-purpose ferments vessels — sourdough starter, kimchi, kombucha, pickles, mead, even laundry dryer ball storage, which tells you they've cast a wide net on the marketing side.

What's actually interesting is the target buyer. On a site like GutPath, the audience skews toward people fermenting food for gut health — which means sauerkraut, kimchi, and water kefir are the real use cases. These jars slot right into that workflow. The 1.5 gallon capacity means you're not constantly replenishing a small jar when you want to make a week's worth of probiotic-rich veggies. For context: one average head of cabbage, once shredded, fills just over half a jar. That left me enough room to add a weight and still seal it.

Key Features

• 1.5 gallon (5.7L) glass body with 4.3-inch wide mouth opening
• Airtight lid with integrated airlock valve for automatic gas release
• Printed scale lines in both milliliters and fluid ounces
• Transparent glass lets you check ferment progress without breaking the seal
• Includes 2 jars, 3 airlocks, and a setup manual per package
• Drop-tested packaging to reduce breakages during shipping
• Versatile enough for sauerkraut, kimchi, kombucha, sourdough starter, and small-batch mead

Hands-On Review

I set these up on a Saturday morning — the kind of weekend project that sounds simple and then somehow eats three hours. Unboxing was straightforward. The jars were wrapped in foam, no chips, no cracks. First thing I noticed: the glass has a satisfying heft. Not so heavy that it feels like a负担, but enough that you know there's substance there when you pick it up.

The first real ferment was a cabbage-and-carrot sauerkraut. I packed the wide mouth jar, salted everything down, weighted it with a clean stone I'd boiled for 10 minutes — and that's when the wide opening genuinely paid off. Reaching in to press the vegetables below the brine was effortless compared to my older narrow-neck jars, where I'd inevitably end up with cabbage leaves draped over the rim and brine dripping sideways.

After two weeks at room temperature (around 68°F/20°C), the kraut was tangy, crunchy, and the airlock had clearly been doing its job. I didn't smell anything off — no moldy or alcoholic notes. The gasket on the lid created a decent seal, and the airlock chamber had its usual small pool of liquid, which is normal.

Week three introduced a kimchi batch. Here's where I'll be honest: I was skeptical about whether these jars could handle a spicy paste without staining or retaining odors. After a week of lacto-fermented gochugaru paste, the glass cleaned up fine with warm water and a soft brush. No staining. The scale lines? Still legible, though I did notice they started looking slightly faded after my third jar-washing session.

There's one thing nobody mentions in the listings: the airlocks need water in the chamber to function. I forgot to top mine off during week four and noticed the valve wasn't releasing properly. A quick fill-up and it was back to normal, but it's the kind of detail you only learn by doing.

Who Should Buy It?

• Home fermenters making large batches — If you go through sauerkraut or kimchi quickly, the 1.5 gallon size means one batch lasts longer and you refill less often.
• Sourdough bakers who maintain a starter — The wide mouth and volume make feeding and stirring a daily starter far less fiddly than standard mason jars.
• Kombucha brewers needing secondary fermentation vessels — The airtight lid with airlock keeps your brew safe from fruit flies while allowing CO2 to escape during second-ferm carbonation.
• Beginners who want everything in one box — The bundle includes jars, lids, airlocks, and a manual. No guesswork about what else to order.

Skip this set if you primarily ferment small quantities — half-cup to one-cup batches of hot sauce or single-serving krauts. These jars are built for volume, and a half-empty large jar can mean your ferment dries out faster near the surface.

Alternatives Worth Considering

Masontops Fermenting Crocks — If you prefer a ceramic crock with a water-seal moat over plastic airlocks, Masontops offers a more traditional fermentation experience. They're heavier and more fragile, but some ferments benefit from the stoneware's thermal mass.

Hydro Flask 64oz Wide Mouth — For cold-side fermenting (like cold-brined pickles or keeping a sourdough starter in the fridge), a vacuum-insulated stainless option keeps temperatures more stable. Just note: no airlock, so you'd need to vent manually.

EasyFerment Premium Fermentation Kit — Comes with weighted glass fermentation weights and a ceramic airlock lid, which some users find more durable than the plastic airlocks included here. Pricier per jar, but the components tend to last longer.

FAQ

Final Verdict

The Sovietiep 2 Pack Large Fermentation Jars deliver genuine value for anyone serious about home fermentation. The 1.5 gallon capacity is practical, the wide mouth solves the usability frustrations I kept having with narrower jars, and the airlock-lid combo works as advertised — once you remember to keep water in the chamber. They're not the most premium-feeling vessels on the market, and the printed scale lines will eventually fade with heavy use, but for the price point, these are a reliable everyday workhorse for gut-health-friendly ferments. I'd keep using them.
