The Kegco 4.755 Gallon Wide Mouth Glass Carboy is the ideal fermentation vessel for 3 gallon batches! These glass jars do not scratch easily, making them easy to sanitize and preventing them from holding odors after fermentation. They are airtight and do not break down over time so if you handle them with care, they can provide decades of great performance.

Unlike normal carboys, they have a wide mouth which allows you to reach all the way inside, making adding or removing ingredients and cleaning much easier. Stick your whole arm inside the vessel to reach all of the surface area with a cleaning cloth, ensuring bacteria has no place to hide. The screw top lid ensures that it stays on throughout fermentation and won't slip out like a foamy bung! The lid features a removable cap in a recessed area that can double as an air lock or hold a #3 stopper for your own air lock. What's more, handy carrying straps make transporting the jar a breeze!

Available in 3 Sizes - 4.755, 5.5 and 7 Gallon

Wide Mouth Makes Cleaning Easier Than Ever

The glass jar is less likely to get scratched up than a plastic carboy or bucket, so these jars are already easy to clean, but the wide mouth makes it even more convenient than a normal carboy. Stick your whole arm inside the vessel to reach all of the surface area with a cleaning cloth, ensuring bacteria has no place to hide.

Install Your Own Air Lock

When using this jar as a fermenter, gas will be released from your brew. If the vessel were sealed airtight, the added gas could cause the jar to explode if not vented properly, but if there is not a good seal, your brew could be come oxidized. The removable cap on the lid allows you to install a drilled #3 rubber stopper with your own air lock so the gas can vent without allowing in oxygen.

Built-in Air Lock

The lid has a recessed area with a removable cap that can be replaced with a breather cap to use as an air lock. The breather cap allows gas to escape from the container during fermentation and having it in a recessed area allows you to fill it with sanitizer so that the released gas can bubble out, but harmful oxygen and impurities cannot get in and contaminate your brew.

Adjustable Dial To Set Brew Date

The lid features an adjustable dial that allows you to set the date that you begin fermentation, so if you have multiple batches going at the same time in different jars, it's easy to keep track of when each one started! Simply turn the inner dial to the month and the outer dial to the day. No more sticking a piece of tape on the side with a date scribbled on it!

Durable Straps Make Carrying Easy

If you've ever tried picking up a slippery jar that's filled with a few gallons of liquid, you'll appreciate the convenience and safety of having a strong woven nylon strap to lift and carry the jar from place to place. The straps fit snugly around the jar and criss-cross the bottom to evenly support the weight, but can be quickly slid off the jar for cleaning.
