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.

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.

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.

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.

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

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.

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:(

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.

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.

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!

Light weight and a little easier to clean than my better bottle. Love the 6gal size. Great price for what you get!

This is my primary fermentor. Easy to use easy to clean and the 6 gallon size allows plenty of room for krausen.

Great fermentor but the plastic arrived hazed and does not come out when cleaned.

Very nice and light weight but yet seems very ridged. i like that there are no ridges on the inside and using a PBW solution soaking overnight it makes for clean up a breeze!!! even hard caked on messes! if any the only down side i can think of is i'm use to my 6.5 gallon glass carboy and this is only 6 gallons... therefor with out thinking of volumes when brewing it was VERY full and luckily i started my primary with a blow off tube installed:) great product. i'm sure i'll be picking up a couple more in the future.

Seems to flex a bit more than other bottles that don't have flat side. No issues to mention

Please PLEASE somebody make one of these that is 6.5 - 7.0 gallons. Keep everything else the same. I like to get 5.25 to 5.5 in primary (which a lot of people do these days) in order to get the full 5 gal in the keg. If you're anything but a complete novice you know how to treat your yeast. A healthy fermentation will blow out of these for 2-3 days no matter how good your blow-off set-up. Don't let marketing cripple these to upsell the glass. Certainly there are no huge engineering hurdles to make this 0.5 gallon larger! Otherwise.... LOVE it.

No seams or ridges for sediments to cling to. Wish it had a wide mouth so you could get your arm inside to really give it a good cleaning.

I first started out brewing using glass carboys and originally resisted changing over to plastic but after lugging around those full 6.5 gallon acid carboys I thought I would try one and I'm so glad I did. This carboy is a fraction of the weight of a glass one and much easier to carry when full. Like many others I was concerned over the possible oxygen permeable of the plastic carboys but after leaving one of my beers in this carboy for almost 9 weeks there were no "off tastes" or oxidation of the beer at all. They are a bit more difficult to clean especially the crud line from fermentation but a wash cloth soaked in hot PBW water stuffed into the carboy and then swished around for a minute or two takes care of the problem fast. I have now switched over entirely to these plastic carboys both the 6 gallon and 5 gallon models and will never go back to glass.

I do most of my fermenting in these things now. Won't break much lighter than glass flat sides let the thermal wrap (if you use one) have better contact. Combine that with a hood thermowell and you've got pretty rock solid temperature control over your fermentation. The only drawback yes easy to scratch. Use a soak or get a mark's keg washer and you're good to go though. Definitely recommended.

I started off with these instead of glass carboys and I'm so glad I did. They're lighter and far more forgiving than glass carboys. If you drop one of these you may scratch or dent it but you won't risk losing an eye or cutting something vital. The only drawbacks with these is that they are harder to clean will definitely scratch and may dent and they aren't quite as big as glass carboys. Also these are supposed to be more oxygen permeable but I haven't noticed any oxidation in my beer. If you're looking for a new carboy get one of these.

I love these carboys. They are light and virtually unbreakable. Since I accidentally lightly bumped two full glass carboys together destroying both I have used these plastic carboys exclusively with no problems.

Pros: light inexpensive big Cons: scratches easily deforms if held wrong I keep one of these as an extra fermenter; it works well but I can't abuse it like my glass carboys. Strong brushing will scratch the insides so clean it out quickly and well after a fermentation.

I know there are two camps glass & plastic. I rest firmly in the glass camp. I would rather lift extra weight carefully than have to continually replace my carboys due to scratches or risk infections. If you are in the plastic camp then this is a solid carboy at a reasonable price.

Guys these plastic carboys are really easy to clean ! Great product. Tom M

Glass carboys are such a pain These plastic carboys are a good Investment.

I recently purchased this carboy to replace my 5 gallon one. This one works great and is easy to clean. The 6 gallon left plenty of head room for fermentation of my 5 gallon batch. When I was using a 5 gallon carboy I ended up losing too much precious ale to the blow off tube. That was one of the main reasons for my upgrade to the 6 gallon.

I've got plastic buckets and glass carboys so I figured I'd give these a try. The plastic in these bottles does not scratch as easy as the buckets and you don't have to worry about slicing your arm off like you do with glass. 6 gallons gives you enough head space to do most of your primary fermentations without blowoffs. Very happy with these and the price couldn't be beat either.

These PET carboys are the way to go. They are very easy to use and very easy to clean. No brush required. Let it soak in PBW and rinse. Love it. This 6 gal carboy even has a mark at 5 gal. This is invaluable. Wish all PET carboys had this.

I like the weight reduction that is the key benefit to going with the plastic. However watch out for scratches especially when cleaning. Plan to replace fairly often.

Not a bad fermenting vessel but not very sturdy. My first bottle came damaged and dented from shipping. More Beer quickly sent out a replacement (Thank you) but the packaging isn't great. Will work fine as a standard fermentor or secondary lightweight just be careful not to drop.

I'm a dedicated PET carboy guy. I've the scars some of my club members bear from their shattered glass carboys. Ever since I swapped from the buckets I've been using plastic for my fermentation and I love them! I did build a carboy cleaner (sump pump in a bucket of PBW) and I think this is critical to using plastic carboys. You can't scrub these with a brush so I let the pump do the work for me!
