Coffee Makers : Question and Answer

A:

While not a hard-and-fast rule, brewers with cone filter baskets are typically preferable to flat-bottom ones because the conical shape encourages water to pass evenly through the grounds to fully saturate them and extract the best flavor. Unless your brewer has an excellent saturation system (ex. Moccamaster or BUNN Velocity), flat-bottom filter baskets can make it more difficult for water to fully saturate the grounds, which compromises the coffee's overall quality.
