A beverage brewer (20) with a dispenser valve (34) for passing brewing liquid from a supply (30) under control by a programmable dispenser cycle dispenser valve controller (36) to intermittently pass the liquid to a uniform flow dispenser head (38) during preselected duty portions (92) of a plurality of control periods (CP1-CP20, FIG. 5B) in order to independently control the total quantity dispensed and the duration of the dispense period (88). The uniform flow dispenser head (38) has a closed body with a perforated bottom (64) that is intermittently filled with brewing liquid during the duty portion selected for each of the control periods to provide a uniform vertical spray across an open top of a uniform ingredient holder (24) within which is held a cylindrically shaped layer of beverage ingredient (70) in order to achieve uniform contact of the brewing liquid with all the beverage ingredient. The dispenser valve controller (36) includes a microprocessor (42) for controlling the dispenser valve (34) in accordance with user parameters entered by a user into a data memory (50) pursuant to a computer program (FIGS. 7A, 7B, 8 and 9) to automatically adjust the duty portions to maintain a preselected dispense period duration for different total dispense quantities and to maintain a preselected total dispense quantity for different selected dispense time periods.
