MMBM / MMUM
Yet another smart product of the MattMill line is the MattMill manometer. It is intended to monitor the pressurizing process of the freshly bottled beer.
All you need is a flip-top bottle (for MMBM). The clamp sold together with the manometer replaces the original clamp so there is no need to try to destroy the white porcelain cap of the original flip-top.
Alternatively the MattMill Universal Manometer (MMUM) also fits regular bottles.
