The first embodiment of the disclosure presents a single cup coffee brewer comprised of two components: a dripper component and a drip rate control component. The dripper component has a brewing container with a flat bottom having a drainage part, and a cylindrical tube member that fits inside the brewing container. A single sheet of Number 4 filter paper is wrapped around the cylindrical tube member, fitting snugly against the drainage part, thereby forming a dripper having a flat bottom using standard filter paper. The drip rate control component is attached to the dripper component, and has a lever that controls the drip control rate from zero to a maximum value. The coffee brewer can therefore be used as a dripper with a user controlled drip rate, or as an infuser followed by a dripper where the user controls the drip rate.
