Abstract
Embodiments of an infusion extractor are provided including a plunger to be inserted into an infusing container containing the infusion mixture that can have vertical inner walls oriented parallel to a vertical axis of the container. In some implementations, the plunger includes a first surface with a seal situated at an edge of the surface. The seal is adapted for sealing against the inner walls of the infusing container as the plunger moves within the container. The plunger also includes a second surface extending from the first surface and defining a second chamber. At least a portion of the extract flow openings are situated at a depth either above or below the first surface along the vertical axis.
