A dual-line spout for maple syrup production is disclosed. The spout has a nose section with an input channel, and an interior chamber having first and second flow paths each fluidly connected to the input channel and to respective first and second output channels. The spout is designed for use with vacuum-based maple syrup productions systems that use a dual-line line system. The dry-line portion of the line system fluidly connects to the first output channel and the wet-line portion of the line system fluidly connected to the second output channel. Example spouts have no chambers, a single chamber or two sub-chambers, to facilitate air-liquid separation. Methods of using the spout in a vacuum-based, dual-line maple syrup production system are also disclosed.
