What is a racking arm?

Answered by Ricardo McCardle

A racking arm is a nifty little contraption that attaches to the side of your fermenter. It’s basically a stainless steel tube that can be rotated to control the flow of liquid.

I remember the first time I used a fermenter with a racking arm. It was like a game changer for me. Before, I had to carefully siphon the beer out of the fermenter without disturbing the sediment at the bottom. It was a delicate process that often resulted in some sediment making its way into the final product. But with the racking arm, I had much more control over the flow of liquid, allowing me to leave behind any unwanted sediment.

The racking arm is typically attached to a port on the fermenter that is specifically designed for emptying the contents. This port can be connected to a keg or a bottling bucket, making it easy to transfer the beer without any mess or fuss.

One of the great things about the racking arm is its versatility. By simply rotating the arm, you can adjust the height at which the liquid is drawn from. This allows you to avoid picking up any sediment that may have settled at the bottom of the fermenter. It’s like having a built-in filter!

I find the racking arm particularly useful when it comes to bottling my beer. By adjusting the height of the arm, I can make sure that I’m only filling my bottles with clear, sediment-free beer. It saves me a lot of time and effort in the long run.

Cleaning the racking arm is also a breeze. Since it’s made of stainless steel, it’s resistant to corrosion and can be easily sanitized. Just give it a thorough rinse with some sanitizer after each use, and you’re good to go.

The racking arm is a simple yet incredibly useful tool for any homebrewer. It gives you control over the flow of liquid, helps prevent sediment from ending up in your final product, and makes the bottling process much easier. If you’re serious about brewing, I highly recommend investing in a fermenter with a racking arm. You won’t regret it!
