Best Carboy

The fermentation process is easily a make or break step in a great homebrew. Brewing can be a lot of work so anything going wrong at the last minute can be extremely frustrating and expensive.

This is why serious brewers invest a lot in proper brewing equipment.

Carboys are very popular in the homebrewing niche and many people consider them to be an essential part of any brewing set up.

What is a Carboy?

A carboy is a rigid, globular container with a narrow neck and typically has a capacity of anywhere from 1 to 16 gallons.

Glass Carboy

These containers may be made from glass or plastic and are used for fermenting brews including beer, cider, kombucha, and wine.

Other names for carboy include jimmyjohn and demijohn.

Why Use a Carboy?

You don’t need to throw out your fermentation bucket just yet. Fermentation buckets are great for primary fermentation. The wide mouth is easy to pour hot wort into while the head space provides plenty of room for the krausen to grow during the fermentation.

Fermenting Bucket

Carboys are especially suited for secondary fermentation. The clear container lets you monitor the process. You don’t have to open the lid to check on the brew, which reduces the chances of introducing contaminants and disturbing the krausen or trub.

Carboys also have limited space at the top due to the tapered neck. This allows for oxygen to flow upwards and out of the container through a blow-off tube or airlock.

You can enjoy these same benefits by using a carboy for primary fermenting.

Glass vs. Plastic Carboys

There is a raging debate in homebrewing circles on which is better; glass or plastic carboys.

The brewing purist will answer glass but the right answer is not that simple.

Glass Carboys Pros & Cons

Glass carboys are the traditional option used for brewing throughout history and for good reason. Glass doesn’t degrade easily (unless shattered) so a glass carboy is a one-off purchase for many brewers.

The smooth interior and exterior glass surfaces prevent contaminants and odors from sticking to the container. This allows you to get through different brews without retaining any of the aromas, flavors, or byproducts of the previous brew.

Glass is also very easy to clean.

The downside of glass carboys is they tend to be heavy. These containers are made from thick and heavy glass which can make the container difficult to transport especially when full.

There is also the potential danger of shattering or breaking a glass carboy accidentally.

Plastic Carboys Pros & Cons

Plastic carboys do have their advantages. They are lighter than their glass counterparts, weighing up to 4 times less than glass. This makes transporting the brew easier. The polyethylene construction also provides a better grip surface than smooth glass.

Plastic carboys also tend to be cheaper which is good if you are trying to keep your overheads to a minimum.

Plastic Carboy

The downside of plastic carboys is the polyethylene construction is prone to scratches. Scratches on or in the container create spaces where bacteria can hide and grow which is bad news for your beer.

Plastic carboys can also be difficult to clean since using a stiff brush or other cleaning equipment can scratch the surface. Finally, plastic carboys have a far lower lifespan than glass options and typically require replacing after every 20-30 uses.

Final Thoughts on the Best Carboys for Brewing

Adding a carboy to your homebrewing set up could make all the difference in beer quality and taste. Opening your fermenting bucket to check on the brew’s progress increases the chances of introducing bacteria and other contaminants to your wort.

Keep in mind that it is good practice to change your fermenting bucket every so often. A good quality glass carboy could save you the cost and hustle of replacing the bucket, which some sources suggest should be changed as often as after every 5 brews.

There are also some great plastic carboys that rival their glass counterparts.

Having the right equipment can make all the difference in the final flavor, clarity, and quality of your brew. Consider adding a carboy to your brewing arsenal to bring the best out of your brewing technique and recipes.
