BouncerMD “Mac Daddy” Inline Filter

As popular as unfiltered beer is right now, there are still a lot of times in the brewing process when you want to filter your in-process beer to some degree. For me, it’s hop trub when transferring from the kettle to the fermentor. Dry hopping can also get you unwanted debris when transferring into your keg. You’ve got process options like whirlpooling or gear additions like bazooka screens for inside your kettle. The Bouncer filter is another option you can add to your toolbox.

The Bouncer filter is like a miniature version of a home water filter. There’s a plastic housing that has inlet and outlet ports, and a clear plastic body that holds the stainless mesh filter screen and screws onto the main housing. The filter screen is made of stainless steel and nylon, and comes in two different mesh sizes. The coarse filter is 20 squares per inch (915 microns), and the fine filter is 50 squares per inch (305 microns).

The Bouncer itself also comes in two sizes- Normal and Mac Daddy. The Normal size comes with barbed fittings to hook up your 3/8” ID transfer hose. The Mac Daddy comes with two sets of fittings- one for 3/8” ID hose and the other 1/2″ ID hose so you can select whatever size matches your siphon or brew kettle valve. The larger Mac Daddy filter also gives you 224% more filter surface area than the base model.

The filter unit is rated for temperatures up to 150F. That means it’s good post-chilling, but not suitable for the hot inlet side into a plate chiller for example. Another creative use of the filter is as a Randall to infuse hops or other ingredient flavors into your beer when serving. More on that in my hands on trial below.
