A beverage filter formed of porous paper, or other paper-like filter material for placement in the ground beverage container of a beverage brewing apparatus, such as a percolating coffee pot, in which the filter is graduated by being provided with indicia in the form of one or more of lines, colored lines, numerals and words, such indicia being affixed on the interior of such filter for readily viewing by the user. In the preferred embodiment, such indicia are affixed in at least two arrangements, one for a mild brew and one for a strong brew. Each arrangement includes markings or indicia for ground beverage level according to the volume of brew desired, such as by cups of coffee, for example. A user, utilizing any dispensing means including the ground beverage container itself, need simply fill the filter to the line corresponding to the desired volume at the desired strength.
