Did you know that your filter shape affects the flavor of your coffee? A flat-bottom filter basket will bring out a coffee's darker characteristics like chocolate and nutmeg, while a conical filter will bring out the coffee's acidity and brighter flavors like berries and jasmine.
The flavor profile also depends on the quality of the coffee you're using. A dark earthy coffee won't become bright and fruity if you put it in a conical filter. Use this knowledge to enhance the flavors that already exist in your coffee!
