Our Plastic Carboy fermenters are made from PET plastic (same as 2L soda bottles) which is far more resistant to oxygen than regular plastic. Plastic PET carboys are safer than glass carboy fermentors. Full carboys can be heavy and hard to maneuver and glass can break resulting in possible injury.

After three years of regular use these carboys still seem to be holding up well. I try to avoid cleaning brushes that potentially could scratch the plastic. Enzymatic or alkaline cleaners work well. Everything comes off with a few days soaking. They carboys are starting to dis-color slightly, but otherwise seem to still have a good, smooth, hydrophobic surface.

These are Great!
I have two of these and have been using them in heavy rotation for around two to three years. No problems whatsoever. They are light, durable, and leave plenty of head space for a five gallon batch.

Will not shatter ar nd cut you.
We all have read the horror stories of broken glass carboys causing emergency room visits. With this carboy there is 0% chance you will be asked who your insurance provider is.

Value play
Better quality than other plastic carboy's I have seen; a bit less flexible so it can handle being moved without completely disrupting the finished beer.

great product
I really like the smooth sides. Construction is beefier than better bottle.

Much Lighter
Much lighter than glass which is good because I sometimes need to move fermenters around to get the right ambient temperature and it's the right size to fit in my lagering fridge.

Light weight & easy to clean!
these are great! super lightweight, but still strong enough to where i've had no issues with them, and very easy to clean being the smooth interior. just a little overnight PBW soak, light brushing, shake it all out, rinse, sanitize and your good to go. i love these things, and gave up on glass all togherther!

the one and only down fall, i wish they were 6.5 gallons, as that's what i was use to with glass. i've had to adjust my recipes down to 5.25 or 5 gallons so there's enough room for the krausen to be contained inside the carboy vs going out the airlock:(

Was hesitant at first, but now I love it!
I've been using a glass carboy for years and never felt the need to switch. After transitioning a few of my old glass carboys to sour fermentors I decided to check out these newfangled PET carboys--I can't believe I waited so long!

I miss the extra half gallon of my glass carboy, but I love how lightweight and durable the PET is. I no longer worry about setting down the carboy too hard or bumping into anything while I move it.

Great fermentor
I love how light it is. Much easier to move around then a glass carboy. I don't notice any difference in the flavor by using this carboy compared to a glass one.

Good alternative to glass
Been using this for awhile now and love the weight of it! Also like the smooth inside compared to the better bottle and is cheaper! I do wish it was a little thicker/sturdier though. Would by again. Got lucky on got my first ones on a buy one get one, which made it an awesome deal!
