Caffe Vita cold brew cans are shelf stable, and brewed with BKON’s patented RAIN™ technology, to express the depth of aroma and complexity of flavor. RAIN™ applies multiple vacuum cycles inside a chamber and removes the air trapped in organic materials to extract from the deepest layers of an element. RAIN™ (Reverse Atmospheric INfusion) is a simple, yet powerful invention that completely changed the rules of flavor extraction.
