The single cup coffee brewer system is adopted to retain a predetermined amount of ground coffee beans for a "perfect" single cup of brewed coffee. The brewing system includes an elongated handle, a basket formed at one end of the handle and a movable basket top member having a leg hinged to the handle. The basket defines a top, peripheral rim and a ground coffee impervious screen at a bottom region thereof. The basket has a predetermined size substantially equivalent to the correct amount of ground coffee for the single cup of brewed coffee. The volume or size of the basket is established below the top plane of the basket rim. The movable basket top member has an elevated basket top cover. The basket top cover includes at least one ground coffee impervious screen disposed over the basket. This permits liquid to flow through the basket and the retained ground coffee beans. The basket top cover has a complementary rim which cooperates with the basket rim to seal the ground coffee beans in the basket.
