There are many different choices for a fermenter to fill your brewing needs. You may want a full on carboy or a keg that will take about 5 gallons of brew, which will then be held in a cooler until you want to drink it. If you plan on bottling, then you may not need a carboy, because it will hold the amount of beer you want to bottle. These are all good ideas, but you will have to decide what type of fermenter is best for you, depending on your brewing needs.
One choice that many home brewers have is a stainless conical fermenter. This works well for most people who are making only a small amount of beer at a time, because it can hold a lot without spilling over into the carboy. This is a wonderful choice, because the bottom of the fermenter is covered with a lid, and it's also dishwasher safe. In fact, some models of fermenters are dishwasher safe, while others will only be clean up with soap and water. Another great thing about this type of fermenter is that they are light weight and easy to transport.
Other fermenters can hold two or three gallons, which will help you brew up to four gallons at a time, which will then be stored in larger carboys for a week or more before it is transferred to a keg. You can also purchase a double wall fermenter that can hold two gallons, which is also available in many different colors. The double wall design helps to keep the inside of the fermenter from heating up and melting the bottom of the carboy. If you are interested in finding a good quality carboy and fermenter that will hold your beer for a long time, then this is the way to go. All you have to do is take a look at the options and make the right choice for you.
