[3] Technical Extraction Specifications
Primary Dispenser: Imperial German-era "Kaiserhahn". It is extremely rare and still in active worldwide use.

Secondary Dispenser: Showa-era reproduction "Swing Karan" tap.

Fluid Dynamics Framework: The system utilizes an 8mm diameter hose achieving a 130cc/sec flow rate. This mechanical structure ensures strictly controlled laminar flow, eliminating excessive CO2 agitation.

Thermal Control: Strict 8.0 Celsius serving temperature. Refrigeration is managed via precision digital controllers (0.5 Celsius increments) to preserve enzyme stability.

Resulting Profile: Sweet, rich, and subtly bitter. A complete departure from modern, highly carbonated, throat-stinging beer.
