4-cup coffee makers are some of the smallest coffee makers available on the market (aside from single cup machines). Traditionally, a cup of coffee is 6oz, which means these cups brew 24oz of coffee at once. These brewers are inexpensive, with most costing around $20, and typically aren't programmable.
Opinions show that with a few exceptions, 4-cup machines tend to be lacking in quality. They do, however, receive great value scores and are good for dorms.
Mr. Coffee offers the most 4-cup models of all brands.
