Abstract: A beverage circuit for cooling a beverage when the beverage flows through inside the circuit, the circuit comprising a hollow tube allowing the beverage to enter into or exit from the circuit; wherein the tube being wounded to form a plurality of multi-layered coiled columns, all of which being arranged substantially in parallel to each other and stacked together column-by-column, each of the coiled columns comprising a plurality of layers; wherein the tube having a cross-sectional width not exceeding 8 mm; and wherein each of the coiled columns having a layer-width not exceeding 80 mm; thereby allowing an entirety of the coiled columns to occupy a compact space while providing a substantial amount of external surface area for the portion of the tube along the coiled columns to allow rapid cooling of the beverage.
