Bazooka Screens & False Bottoms

Bazooka Screens & False Bottoms

If you are brewing an all-grain beer recipe, a false bottom is a must! We will explain the difference between a bazooka screen and a false bottom so that you can decide which kettle accessory is right for you.

Bazooka screens (AKA kettle screens)are mini versions of false bottoms. Made from stainless steel mesh, they attach to the inside of your boil kettle to strain any hop or grain particles from your wort when transferring to your fermenter. Depending on the size of your brew pot, you could use a 6" or 12" bazooka screen attached to your ball valve or solder our 12" double-ended screen to a 1/2" brass or copper fitting, then connect to your ball valve to drain from the middle of your brew kettle.

Using a false bottom separates your mash from your wort, and failure to do this correctly could make for stuck mashes, lots of spent grain and husks (which could contribute to a bitter phenolic taste) and just a slow runoff. Generally, after mash out, you would want to do a “recirc”, and you do that by (depending on your setup) pouring off a few litres at a time of wort and gently pour back the wort on top of your mash bed. If you do this, it allows any sediment that has settled at the bottom of your tun to be cleared out and placed back on the filter bed.

Not too sure what size false bottom you need for your brew kettle? Please take a look at the False Bottom Comparision Chart that Barley did; it lists all the popular sizes and will let you know what size brew pot it fits.
