Machines and methods for preparing single-servings of a beverage. The machine can include a housing and a basket assembly positioned in the housing. The basket assembly defines a chamber capable of receiving a cartridge containing a beverage precursor. A screen having a plurality of openings can be positioned at a bottom portion of the chamber. A first plate having a single restricting orifice can be secured to the screen.

1. A machine for preparing single-servings of a beverage, the machine comprising: a housing;a basket assembly positioned in the housing, the basket assembly comprising a chamber capable of receiving a cartridge containing a beverage precursor;a screen positioned at a bottom portion of the chamber, the screen comprising a plurality of openings;a first plate secured to the screen, the plate having a single restricting orifice configured to restrict flow of fluid therethrough; anda spring-loaded relief valve, the relief valve configured to move from a closed position to an open position when a pressure between the screen and the first plate exceeds a cracking pressure to vary a flow area of the restricting orifice. 2. A machine for preparing single-servings of a beverage, the machine comprising: a housing;a basket assembly positioned in the housing, the basket assembly comprising a chamber capable of receiving a cartridge containing a beverage precursor;a screen positioned at a bottom portion of the chamber, the screen comprising a plurality of openings;a first plate secured to the screen, the plate having a single restricting orifice configured to restrict flow of fluid therethrough; anda needle valve having a plunger secured to the screen, a tip of the plunger extending at least partially through the restricting orifice, the needle valve selectively adjustable to vary a flow area of the restricting orifice. 3. A machine for preparing single-servings of a beverage, the machine comprising: a housing;a basket assembly positioned in the housing, the basket assembly comprising a chamber capable of receiving a cartridge containing a beverage precursor;a screen positioned at a bottom portion of the chamber, the screen comprising a plurality of openings;a first plate secured to the screen, the plate having a single restricting orifice configured to restrict flow of fluid therethrough; anda spring-loaded check valve positioned below the restricting orifice, the spring-loaded check valve configured to move from a closed configuration to an open configuration,wherein: the check valve moves from the closed configuration to the open configuration when the check valve is in an inverted position and fluid flows in a downstream direction, orthe check valve moves from the closed configuration to the open configuration when fluid flows in an upstream direction. 4. A machine for preparing single-servings of a beverage, the machine comprising: a housing;a basket assembly positioned in the housing, the basket assembly comprising a chamber capable of receiving a cartridge containing a beverage precursor;a screen positioned at a bottom portion of the chamber, the screen comprising a plurality of openings;a first plate secured to the screen, the plate having a single restricting orifice configured to restrict flow of fluid therethrough; anda leaf spring, the leaf spring: (a) positioned below the restricting orifice, or (b) positioned across the restricting orifice, the leaf spring configured to move from a closed configuration to an open configuration. 5. The machine of claim 4, wherein the leaf spring is positioned across the restricting orifice, the leaf spring configured to move from the closed configuration to the open configuration. 6. The machine of claim 5, wherein the leaf spring moves from the closed configuration to the open configuration when the leaf spring is in an inverted position and fluid flows in a downstream direction to vary a flow area of the restricting orifice. 7. The machine of claim 5, wherein the leaf spring moves from the closed configuration to the open configuration when fluid flows in an upstream direction. 8. A machine for preparing single-servings of a beverage, the machine comprising: a housing;a basket assembly positioned in the housing, the basket assembly comprising a chamber capable of receiving a cartridge containing a beverage precursor;a screen positioned at a bottom portion of the chamber, the screen comprising a plurality of openings;a first plate secured to the screen, the plate having a single restricting orifice configured to restrict flow of fluid therethrough; anda second plate and a compression spring positioned between the first plate and the second plate, the second plate having a plunger extending at least partially through the restricting orifice when the first plate is moved toward the second plate.
