I'm a long term homebrewer but I have always done single step infusion mashes. I've always wanted a RIMS or HERMS system but I don't like the space a full system takes up and I've always backed off because of the cost. But what about a self contained portable RIMS tube system? Something I could use with my existing 10 gallon GOTT cooler mash tun? Well, that's how my portable RIMS tube was born. It's light, only 17 pounds and can easily be stored the 20 something days of the month when I'm not brewing beer. So, it keeps the wife happy too because I'm not taking up so much space in the garage.

This is a step by step guide for building your own portable RIMS tube.

Here is an updated instructable, showing you how to attach a more permanent RIMS tube to your brew stand.

Since posting this instructable we have been answering email requests for a RIMS tube kit and we finally put a kit together minus the pump and base. You can find our RIMS tube kit here!
