Unfiltered coffee includes methods like French press, Turkish coffee, and espresso—where no paper filter removes the oils and fine particles.
Paper filters trap coffee oils and sediment, producing a cleaner cup. Unfiltered methods let these through, creating a fuller body and different flavor profile. There are trade-offs to consider: unfiltered coffee contains compounds called diterpenes that can raise cholesterol levels. For occasional drinkers this is not a concern, but if you consume multiple cups daily, it is worth understanding the health implications.
