A hot beverage that is made by filtering hot water through ground coffee beans, popular for its aroma and concentrated dose of caffeine. Use this tag when coffee itself (ordinarily a black or dark brown liquid) is visible in an image.
It is normally served in a porcelain mug, but it can be taken on the go in a stainless steel mug or styrofoam cup. Modern coffee shops often use disposable paper cups with a snap-on lid and an insulating cardboard sleeve. These should be tagged coffee cup. For the traditional porcelain or ceramic "coffee cups" that aren't mug-shaped, see teacup.
As coffee can be quite bitter, it is often served accompanied by sugar and milk or cream. It is usually consumed while hot, but it may be served over ice.
