K-CAP 3D Model - how it looks like

KCAP self-regulates carbonation levels in your handcrafted beer, unfiltered and unprocessed. Its appearance and feel mirror those of a standard crown cap, with one notable exception: the tiny hole. This proprietary design enables excess CO2 to escape from the bottle, effectively preventing oxidation and contamination at the same time. The membrane filters out impurities from liquids, yielding superior results even when bottles are stored in horizontal positions.
