<p>A beverage flow controller includes a tube (16) having a first end and a second end, and a length between the first end and the second end including multiple constrictions (17, 19). The constrictions (17, 19) have a center to center spacing of at least 4.5 times the diameter of the tube (16) and have an inside diameter of 0.6 to 0.8 times the inside diameter of the tube (16). The constrictions (17, 19) control the flow and provides a pressure gradient along the length of the tube (16).</p> |
