Best Auto Siphon for Brewing: Top 5 Picks

Homebrewing takes place in stages, and a few of those stages involve moving the wort from one container to another without disturbing the trub.

Siphoning beer from a fermenting bucket to another is also known as racking, the process that is used to convert complex sugars the wort contains into alcohol.

It’s also one of the most efficient ways of protecting the wort from direct exposure to oxygen and bacteria that would contaminate it or alter its taste.

An auto siphon will enable you to go through the racking and bottling processes effortlessly. This guide to the best auto siphons for brewing will help you determine which of these invaluable pieces of homebrewing equipment is right for you.

What is an Auto-Siphon and Why Do I Need One?


To understand what an auto-siphon is, you first need to know how a basic siphon works. These devices rely upon the laws of physics to transfer fluids from one container to another.

A siphon enables the smooth transfer of liquid from one container to another through gravity, which means the position of containers is vital for the siphoning to work. Position your bucket of wort on a counter or table with another bucket below it.

Submerge one end of your siphon into the wort (if there’s trub in your bucket, make sure the end of the siphon stays above the sediment) and place the other end in the bucket below. Gravity will facilitate the flow of liquid through your siphon, though you need to get it started. 

Basic siphons can be tricky to use, unsanitary, and can sometimes even leave you with a mouth full of wort! In order to initiate the flow of liquid, you need to take one of the following steps:

  • Fill the tubing with sanitizer, plugging one end with your thumb and submerging it into the wort before releasing. This will cause the sanitizer to flow from the tube, eventually pulling beer along with it. You can catch the sanitizer in a bowl and then place the free end of the tube into your receiving bucket once the beer starts to flow. It’s effective, but difficult to time it right, and messy if you make a mistake (trust me on that one.) 
  • Submerge one end of your siphon into the wort and suck the other end until beer begins to flow. This isn’t the most sanitary or pleasant method, especially if you accidentally get a mouthful of wort in the process. .

Auto Siphons don’t require you to use your mouth (or cat-like reflexes) to start the flow of liquid. They’re also designed to filter out the trub and only transfer wort.

The Main Components of an Auto-Siphon

An auto-siphon is a simple device that consists of a racking cane tube and a hose that transfers fluid from one container to another. Suitable models for moving wort are equipped with a filter at the bottom of the tube that houses the racking cane.

The filter enables the device to separate the trub from the wort so that you don’t have to deal with sediment later in the homebrewing process. The racking cane is a plastic tube that is placed inside a larger plastic tube.

You’ll find a 90-degree bend on the upper side of the racking cane and a plunger at its bottom that stops the airflow and creates a vacuum within the device.

Much like basic siphons, auto-siphons will only be effective if the siphon tubing is placed in the downward position, which means that the fermenting bucket which holds the wort needs to be above your secondary container.

Sanitizing an Auto-Siphon Before Use

Benjamin Franklin said, ‘By failing to prepare, you’re preparing to fail.’ When applied to homebrewing, Franklin’s statement suggests that failing to get each piece of equipment you’re going to need to complete a particular step can end up ruining the entire batch of beer.

Sanitization is one of the key preparation methods you need to use before commencing each step of the process since contact with bacteria can make your craft beer undrinkable.

That’s why you have to sanitize all parts of the auto-siphon along with the secondary fermenting bucket before you initiate the racking process. The easiest way to do this is to fill a fermenting bucket with the disinfectant bleach solution and then empty it using the auto-siphon.

You should rinse the bucket and the auto-siphon before you start moving the wort from the primary to the secondary container. Apply extra caution when using the racking cane because it can break if you use too much force.

In addition, you should inspect the siphon tubing regularly and get a new hose when you notice stains or dirt.

Using an Auto-Siphon for Racking

Bottle Filler

Although the racking process is straightforward, you still have to tread carefully through each step. Arguably, the most important thing you need to do is to move the fermenting bucket that holds the wort you’ll be transferring to the desired location a few hours before starting the racking process.

This will give the trub you disturbed while moving the bucket the time to settle at the bottom. When ready, submerge the sanitized racking tube in the wort, and direct the hose into the secondary fermenting bucket that should be located below the primary bucket.

In case, you’re bottling beer, you should consider getting a bottle filler that will enable you to control the flow and keep the spillage at a minimum.

You should lift the racking cane while submerging the device in the wort and then push it down to establish the flow of the wort. Making sure that the auto-siphon hose remains under the fluid level will reduce the chances of oxidation.

Managing the Trub

The sediments at the bottom of the fermentation bucket should remain undisturbed throughout the racking process. Auto siphons are equipped with sediment blocking tips at the bottom of the outer tube that prevents a trub from entering the system.

However, blocking tips can’t keep all the sediment from entering the tube, and therefore, a certain percentage of the trub will reach the new container.

This isn’t such a big deal if you’re preparing the wort for the secondary fermentation process, as the sediments will eventually fall to the bottom of the bucket.

You need to pay more attention to the trub while using an auto-siphon to bottle beer because you won’t be able to filter it after the bottling process is completed.

Hence, you should avoid moving the bucket hours or even days before racking or bottling your craft beer to ensure that sediments produced during fermentation remain at the bottom of the bucket.

Factors Worth Considering While Choosing an Auto-Siphon for Brewing


The differences between auto siphons for brewing you can find on the market are minuscule. Most models look almost identical. They’re usually made of clear, hard plastic that makes them moderately resistant to physical damage.

Whichever model you choose, chances are it will last through several homebrewing sessions. Even if your auto-siphon breaks down, you can replace it for less than $20.

Following a set of guidelines while choosing an auto-siphon will eliminate the need to purchase a new one every time you want to try a new beer recipe. Let’s take a look at the factors that can help you find an auto-siphon that will meet all your homebrewing requirements.

Make Sure to Go Through the Offer of Home Brewing Starter Kits

Check the Diameter of the Auto Siphon’s Racking Cane

The size of an auto-siphon determines how long the bottling or racking process is going to take. Models that have a 3/8-inch diameter are generally better suited for bottling because the flow of the fluid is slower and easier to control.

½-inch automatic siphons are much faster, which makes them a great choice for racking large amounts of wort or if you want to store the beer in kegs.

Get a Model That Ships With a Hose

The hose, or siphon tubing, is an essential piece of an auto-siphon. 

The majority of auto-siphon models come with the matching hose, so you won’t have to go through the trouble of searching for a hose that is compatible with the auto-siphon model you got.

However, if you need longer siphon tubing or choose a model that doesn’t ship with a hose, you need to check its racking tube diameter and then purchase a hose for homebrewing.

Opt For an Auto-Siphon Made from Durable Materials

Applying too much force to the racking may cause it to break, which in turn may postpone your racking plans.

Choosing a model with a racking cane made of hard plastic will ensure that you can transfer wort without any difficulties.

The advantages of auto siphons for brewing

Prevents Oxidation of Wort

Introducing vast amounts of oxygen into the wort during the racking process can ruin the beer’s taste. Auto siphons enable you to minimize the chances of oxidation by transferring wort at a steady rate to another container with minimal splashing.

Protects the Wort from Bacteria

Using an automatic siphon will keep the airborne bacteria away from the wort so that they can’t affect the fermentation process.

Simplifies the Bottling Process

Bottling homebrew beer can get messy if you can’t control its flow from the fermentation bucket into a bottle. An automatic siphon that is equipped with a bottling wand lets you control the beer’s flow, and it minimizes waste.

The Disadvantages of Auto Siphons for Brewing

Upkeep Can be Challenging

Cleaning and sanitizing an auto-siphon before and after every use is necessary if you want to continue racking beer with it.

Ensuring that you’ve sanitized the auto-siphon properly can be tricky as some components are hard to reach.

Frequently asked questions about auto siphons

Question: Can I rack beer with a basic siphon?

Answer: Yes, you can, but doing so will disturb the sediment at the bottom of the fermenting bucket, and sucking the air out of the tube with your mouth might expose the beer to bacteria.

Question: How long does the racking process take?

Answer: The duration of the racking process depends on the size of the beer batch, but transferring a gallon of wort to a secondary fermentation bucket can take between 10 and 20 minutes

Question: Are auto siphons expensive?

Answer: No, they’re not. You can purchase an auto-siphon capable of transferring gallons of beer for less than $20.

Question: Is it possible to transfer beer with a racking cane?

Answer: Yes, it is. Auto siphons include a racking cane in the setup, but you can get rid of other parts of the system and just use a plastic or metal tube that is bent at the top to siphon beer from one container to another.

The verdict – How to Know Which Auto-Siphon Model is the Best for Brewing?

The necessity of secondary fermentation has been a hotly disputed topic among homebrewers around the globe.

Even if you think that racking beer is an unnecessary step that leaves too much room for error, potentially ruining the entire batch of beer, you’re still going to want an auto-siphon to complete the bottling process.

These devices all operate the same way, relying on gravity to transfer fluid from one container to another. 

For the average homebrewer, I recommend the North Mountain Supply Quick Start Automatic Siphon because it contains all the components you need to start a racking process.

Homebrewers in need of an automatic siphon capable of transferring large quantities of beer from one bucket to another should consider getting the FastRack Auto Siphon.
