Last weekend I built a hop randall, something I have been wanting to do for a long time. For those who are unfamiliar with the name, a randall, also known as a moorminator, hash back, or beer infuser, is a device that is placed inline between a keg and a draft faucet that allows you to infuse additional flavors into a beer. There are several designs, ranging from cheap - a French Press or a thermos with a filter - all the way up to the overkill solution offered by Dogfish Head.I opted to go for the tried and true water filter based design, as it seems to be the most prevalent and is relatively cheap to build yourself - there are pre-built models available from several homebrewing sites as well as places like Amazon and eBay for about $100, but you can build one yourself much cheaper.
I opted to go for an all-stainless (save the filter housing) design, because stainless. Many of these parts are available in brass/plastic (nylon or PVC) versions as well for less. The design I chose uses a Ball Lock post on one side and a disconnect on the other so I can easily daisy-chain the Randall into my system without having to mess with anything, but there are other options as well if you look around.
Check out the build after the break.
