A typical bean of Coffea arabica contains about 0.6% cafestol by weight. Cafestol is present in highest quantity in unfiltered coffee drinks such as French press coffee or Turkish coffee/Greek coffee. In filtered coffee drinks such as drip brewed coffee, it is present in only negligible amounts.
Clinical significance 
Cafestol has also shown anticarcinogenic properties in rats. Cafestol may act as an agonist ligand for the nuclear receptor Farnesoid X receptor and Pregnane X receptor, blocking cholesterol homeostasis. Cafestol has also been implicated in inhibiting the progress of Parkinson's disease.
