Fermentation vessels: Buckets Vs. Better Bottles Vs. Glass Carboys Vs. Plastic Water Bottles Vs. Corney Kegs

Cheap

Readily Available

Opaque, which prevents skunking

Easy to modify if they aren't pre-drilled for an airlock

Light weight

Built in handle

Wide opening makes cleaning a breeze

Wide opening also makes sanitation a breeze. Spray it with sanitizer, then just flip it upside down to drain

Unimpressive looking

Lids often seal poorly. While this isn't a bad thing for people who know what they're doing, it often scares the new folk when they don't see their airlock bubbling

Plastic scratches easily, which can harbor bacteria

Opaque, so you can't see the beauty of fermentation

Some use gaskets instead of drilled stoppers. These gaskets love to fall into the beer when an airlock is added.

Can't use a wort wizard with a bucket

Even with careful handling and proper care, a bucket won't last you a lifetime

If you do get an infection (which is uncommon, borderline rare with proper sanitation) you'll most likely have to throw away any plastic equipment to prevent further batches from becoming infected.

Generally they have a lot of headspace. This isn't a problem for primary fermentation, as CO2 will displace the air in your bucket. It can, however, pose a problem if you're using it for a secondary. You can boil a few thousand marbles to sanitize them, then rack your beer on top of that. Seems like more hassle than it's worth to me, but I don't usually secondary

Less expensive than glass carboys

Transparent, so you can watch the fermentation

Firm seal with a cheap stopper, so you can be sure to get that happy music out of your airlock

Wider mouth than glass carboys. You can insert a seriously massive blowoff tube.

Light weight. Easier to move and cheaper to ship than glass carboys. Also easier to sanitize than glass carboys if you use the Llama method of 1 gallon of water, Star San, and shaking the **** out of it for a few minutes

Has a handy indentation on the underside. This makes aeration a breeze if you stick a tennis ball underneath and just spin it like mad

Looks pretty cool compared to a bucket

Can come with a built in racking set up

Easier to drain Star San out of. If you fear the foam, you can flip it upside down over the sink and give it a few gentle squeezes. That puffs most of the foam out

Nearly indestructible. Edwort made a nice video on Youtube about how tough they are.

The racking modification easily doubles the price

More expensive than buckets

Transparent, which can allow light in. Easily remedied by draping a dark t-shirt over the BB

Cannot handle negative pressure. You can still use a wort wizard with them, but you have to burp them a few times

Made of plastic, which can become scratched if you try to use a carboy brush on them

Only available in 3, 5, and 6 gallon sizes. If you're making a big beer, and using a 6 gallon primary BB, you can expect a decent blow off. If you're using a 5 gallon BB for primary for just about any beer, you can bet on blow off 90% of the time

If you make a post about how much you love better bottles on HBT, someone will inevitably chime in about oxygen permeability

If you do get an infection (which is uncommon, borderline rare with proper sanitation) you'll most likely have to throw away any plastic equipment to prevent further batches from becoming infected.

Any plastic gear you use will eventually need to be replaced. Sorry, but it just won't last forever

You can find them anywhere

Cheap

Less expensive than glass carboys

Translucent, so you can watch the fermentation

Firm seal with a cheap stopper, so you can be sure to get that happy music out of your airlock

Light weight. Easier to move and cheaper to ship than glass carboys. Also easier to sanitize than glass carboys if you use the Llama method of 1 gallon of water, Star San, and shaking the **** out of it for a few minutes

You can drill a hole and install a bulkhead to create a racking modification similar to that used with better bottles

Some of them have built in handles

Some aren't made of #1 or #2 plastic, making them unsuitable for our purposes

IMHO, they look cheaper than the buckets

If you do get an infection (which is uncommon, borderline rare with proper sanitation) you'll most likely have to throw away any plastic equipment to prevent further batches from becoming infected.

Translucent, which can allow light in. Easily remedied by draping a dark t-shirt over the bottle

Made of plastic, which can become scratched if you try to use a carboy brush on them

Cannot handle negative pressure. You might still be able to get away with a wort wizard if you burp it as with a BB

Any plastic gear you use will eventually need to be replaced. Sorry, but it just won't last forever

Does have higher oxygen permeability, so you might not want to bulk age in a water bottle for more than a few months

They just plain look awesome. If you're going for the mad scientist look, glass is the way to go

They can be cleaned with a carboy brush. You can scrub the crap out of them without fear

Can handle negative pressure, if you use a wort wizard

With proper care, they can outlive you

Transparent, so you can watch the fermentation

You get a great seal, so your airlock will bubble away happily

Most any homebrew store will have tubing that fits straight into the neck for a pretty big blowoff tube

Most any homebrew store will sell accessories specifically made for glass carboys. Carriers, caps, blow off tubes, etc...

Drop it once, and it's a dead carboy

Many people have had to go to the hospital because of glass carboys. Gotta be careful with these things. See this: Broken Glass Carboy Horror Stories Compendium

Most expensive fermenter on this list

Heaviest fermenter on this list. Makes cleaning and aeration harder, and makes shipping much more expensive

Recently glass carboys have seen a huge degradation in manufacturing quality. We've seen a few break for what seemed like no reason

just thought I'd take the time to clear up a few common newbie issues about which product is better. Just so we're clear, for 99% of these issues, both options work equally well. It's usually just a matter of preference, so I thought I'd assemble a list of pros and cons of the most frequently asked about products.(Please note that this list does not include conical fermenters. Odds are, if you are willing to invest that kind of money, you probably already know the sweeping benefits of a conical. That, and I'm poor, and can't afford a conical, so I have no experience there.)Pros:Cons:Pros:Cons:Pros:Cons:Pros:Cons:Pros:1. No glass carboys to break.2. No delicate plastic surfaces to scratch and consequently harbor bacteria.3. No UV worries.4. Very tolerant to temperature.5. Convenient carry handles.6. Interchangeable vessels/ streamlined process. I can ferment, age, bottle and serve from all the same containers.7. Not finicky to sanitize, I can use whatever product I want.8. Dented cornies can be hammered back out with a rubber mallet.9. Can be stored sanitized and pressed with a little CO2 more or less indefinitely, thus I can brew anytime without having to check if the primary is clean.10. All one container type. I usually wait until I have three or four (used, rinsed) backed up before I bother breaking out the OxyClean.11. Since I can harvest yeast out of cornies I am somewhat less interested even in conicals.12. Can tolerate spunding valves/ pressurized primary ferments.13. Carboy brush is quaint reminder of bygone era.14. Cornies tolerate sharpie marker labels directly on bare steel, cleans up easily with hot water, OxyClean, green scrubber. Just to the side of the black post in case of drips...Cons:1. More expensive than buckets, more expensive than carboys. Cheaper than conicals though ;-)2. O-rings are less durable than glass.3. Several parts to keep track of, organizational skills required.4. Multiple surfaces means cornies are less forgiving of marginal sanitation pratices.
