What is the effect on brewed coffee if the temperature of the water is above or below 185-203 °F?
If the water is boiled, dissolved oxygen will escape and result in flat-tasting coffee. Coffee will also be less flavorful since boiling causes the loss of volatile compounds. Higher temperatures result in excess extraction of bitter compounds. Lower temperatures do not extract enough flavor.
