Coffee: Which type of filter do you use? There is a difference!

(See my other Coffee and Food  related posts) – The University of California, Davis Coffee Center has been investigating the best ways to brew coffee. In March of 2019 the article “Flat vs. Cone: Basket Shape is as Important as Grind Size in Drip Brew Coffee” was published in 25 Magazine.

A very well designed [see the article for details] experiment was designed to evaluate flat versus cone shaped filters. The quick take from the article:

  1. filter shape does affect the taste of coffee
  2. grind size does not affect the taste of coffee
  3. there is a taste difference between light and dark roasts

With light roast:

  1. flat bottom filters “yielded flavor attributes with more dried fruit, sweet, and floral flavor intensities
  2. cone filters “yielded more citrus, berry, and sour

With dark roast:

  1. flat bottom filters “yield more pronounced chocolate, cocoa, and woody flavors
  2. cone filters “yield much more intense bitterness

Which filter type is best? That is really up to the consumer because we each have our own taste preferences.
