Best Brewing & Fermentation Airlocks of 2025

"I found the price and performance to be perfect. I used this jug for making mead, and decanting into a pitcher was super easy. The plastic lid has a nice gasket, although I'm a bit hesitant to test it for leaks. For this price, I'll just serve directly from the jug, which is not only cheaper than buying bottles but also easy to pour. I absolutely love it—ideal for first-time brewers!"

"I've been fermenting honey mead in this jug for several weeks without any issues. It feels heavy and durable, and I had no problems with temperature changes during sanitization. The airlock design isn't my favorite, but it performs well. Just need to be careful when removing the lid to avoid splashing. Great price, and I'm planning to buy another one soon!"

"This fermentation system is fantastic! It's easy to assemble and clean. I hope my first gallon of mead turns out perfect. The jug itself is well-packaged and sturdy, though the airlock requires some care with the fill line. Overall, a very nice set for anyone interested in fermentation!"

“I received 3 airlocks and 3 stoppers packed well and everything is in working order. The stoppers are #6.5, with specific dimensions for a perfect fit.”

“I’m using these for my wine making and they work great! They seal my 5-gallon bucket well and allow gas to escape effectively. I’ve reused them multiple times, and they’re very durable!”

“I ordered these for my 1-gallon glass carboys, thinking they would fit, but they didn’t. I found they required too much force and didn't seat properly. They did fit my plastic juice jugs well, but I’ll need to buy the correct size stoppers for my carboys.”

"I've found these to be the best one-gallon jugs for the price, though they are on the heavier side. Cleaning isn't super easy, but I expected that. Just be cautious with fruit meads, as they can bubble over easily."

"I'm really impressed with the excellent quality of these carboys. I didn't experience issues with the bungs fitting, but I recommend drying the rim with a paper towel if you do. I'll definitely be purchasing more in the future!"

"These glass fermentation jugs deserve a five-star review. The airlocks work perfectly to release gases without letting contaminants in. The bungs create a tight seal when the jug necks are dry, which gives me confidence in my fermentation process. They've become an indispensable part of my brewing equipment!"

"I bought this to make a primary fermenter out of a 5-gallon bucket lid. It was super easy—just had to buy the right grommet and drill a hole. I used a step drill to make a hole slightly larger than 1/2". The grommet formed a tight air seal, and my fermenter is bubbling away!"

"I purchased these as backup airlocks and spares. They work GREAT, but if fermentation is really strong, they may pop out. Cleaning is simple, just rinse out the bottom and sterilize the stopper. I found a solution to keep the rubber stopper in place, and it really works!"

"I bought these for my 1-gallon glass jugs, but unfortunately, the bung didn’t fit my tiny hole. Quality was a concern; one piece arrived broken, and they felt incredibly thin. I struggled with getting the water in the right location for proper function. Overall, they were decent for the price, but I prefer a more durable option."

"This worked great for my wine fermentation. It's sturdy and easy to wash. My wine turned out great, and no bugs got into it. I recommend it for wine making/fermentation and think it's a good value for the money."

"I drilled a 1/2" hole in a 3-gallon bucket lid, added water, and placed it over my pepper mash. It fermented for 30 days, and I saw bubbles escaping. For the price, this setup can't be beat!"

"Everything was fine except for the grommets, which were way too small. I had to lubricate them just to get the airlock to fit somewhat. I worry it might slip off. Now, I need to drill a 1/2 inch hole to allow the grommet to expand, but that also means the grommet will fit loosely. It's a bit annoying, especially since I wanted to pull out the airlock for gravity samples. I would have returned them, but I didn't want to wait for a replacement. It's a pain to have to deal with this sizing issue."

"These airlocks arrived just as promised, neatly wrapped and easy to use. They work much better in my half-gallon glass jugs compared to the original ones I purchased from another company. I’m definitely considering buying them again!"

"My wife loves experimenting with different wines, and she's very happy with the quality and pricing of these airlocks. Thank you!"

"I had some trouble with the stoppers not staying in the neck of the carboy, but the airlocks themselves are great. They performed well during my winemaking."

"This product has worked flawlessly for me. I highly recommend it; it's easy to use and perfect for my needs. Just remember to order according to the neck size of your bottles."

"As someone who has never made wine before, I find these to be of good quality. They resemble others I've seen, and I'm excited to start brewing with them."

"For the price, this airlock set is really good. They may be the older style, but they do the job just as well, especially if you're fermenting in a wine juice bucket."

"This airlock provides excellent protection during fermentation, ensuring my products remain uncontaminated."

"I'm very pleased; the grommets feel thick and durable, and having extras is a nice touch."

"Everything arrived in perfect condition, just as advertised. I'm really satisfied with my purchase!"

"I'm looking forward to starting my batch of acerglyn! Just a heads up, I can't remember the drill bit size, but it's definitely not 3/8th."

"While the airlocks are decent quality, I found the included grommets a bit too small for the airlock stem, which made it tricky to use."

“I find this product to be defect-free and made from sturdy hard plastic. It's affordable and allows gases to escape while preventing fruit flies and gnats from reaching my must. I use it for home brewing mead. Although cleaning is a bit tough, this is common with this type of airlock from any vendor. Overall, I would definitely buy it again because it’s a quality product at a low price.”

“I plan to purchase this again. The only downside is that it’s a bit hard to clean, which is why I gave it four stars.”

“This airlock is super easy to install on containers and works exceptionally well!”

"I haven't used them yet, but they look rugged and well-made, and I believe they will perform reliably."

"I appreciate how heavy-duty this airlock is; it handled a violent fermentation from my 5-gallon batch quite well."

"I bought this after reading reviews. Many mentioned the airlock was tough to install in the rubber after it was in the lid. I found that if I drill the hole a bit larger than the rubber grommet's inside diameter, it fits perfectly. The airlock works just as it should in my plastic 2-gallon fermenter buckets."
