About

Owner satisfaction: <p>Owner satisfaction icons are based on the proportion of members who are extremely likely to recommend their drip coffee maker brand to their friends and family.</p>

Brew performance: The ability to reach 195° to 205° F for five or six minutes, the industry standard for optimal brewing and an indication of the coffee's concentration.

Results in the following chart are gathered from Consumer Reports’ 2018 Summer Survey of 42,774 drip coffee makers, owned by members who purchased a new machine between 2008 and 2018.

Our predicted brand reliability ratings are based on a statistical model that estimates problem rates within the first 4 years of ownership, for drip coffee makers that are not covered by an extended warranty or service contract. We also adjust for the median number of days of use per week. The median in our survey was 7 days per week. Higher ratings are indicative of better reliability. Brands receiving a red or orange rating cannot be recommended by CR at this time.

Our owner satisfaction ratings are based on the proportion of members who are extremely likely to recommend their drip coffee maker brand to friends and family.
