We recently introduced our own in-house designed version of false bottoms for use with our Standard Edition Ss Brew Kettles. This new false bottom is a domed design with a center suction point, that utilizes our silicone outer seal, which has become popular on our line of InfuSsion Mash Tuns. Whereas the Norcal design is a flat bottom that utilizes our included dip tube with trub dam.
Both options are very effective at filtering mash, and preventing grain finings from entering your boil kettle. We decided to stock both options because we realize that NorCal false bottoms have a very loyal following. In addition, our own design is intended to better support both international markets, and and our growing list of domestic kettle users.
The bottom line is, you cant go wrong with either option!
