Abstract
In accordance with the present invention, there is provided a coffeemaker with a variable brew strength apparatus which comprises a base which contains a water reservoir and a heater and which supports a coffee carafe. The base supports a variable brew strength apparatus directly over the coffee carafe. The variable brew strength apparatus includes a water restrictor member which is rotably mounted on the cover of a coffee basket member. The water restrictor member and the coffee basket member, in combination, form a valve which either admits heated water to an inner basket which is mounted in the coffee basket and which contains ground coffee, or causes a portion of the heated water to bypass the inner basket and enter the coffee basket to mix with and dilute coffee brewed in the inner basket. The coffee basket supports a special coffee scoop which has a tabular indicia relating the number of cups of coffee desired, the brew strength desired, and the number of scoops of coffee required. Brew strength indicia are provided on the cover of the coffee basket to facilitate the brewing of coffee using an optimum ratio of coffee and water.
