Coffee Brewing Techniques

There are a number of techniques in brewing coffee: concentrate brewing, Turkish or Greek, vacuum brewing, percolating, or the French press (also called press pot or plunger coffee) and drip or filter coffee.

Caffeine by Type of Brewed Coffee

Like all coffee drinks, caffeine levels vary greatly - due to variations in coffee blend, exact amount of ground coffee used, and brewing technique.

Brewed Coffee Type Caffeine per 8 fl. oz.
Drip or Filter 115-175mg with an average of 145mg
French press or plunger 80-135mg with an average of 107.5mg
Percolated 64-272mg with an average of 200mg
Boiled (Turkish or Greek) 160-240mg with an average of 200mg

The value of caffeine in brewed coffee featured above is an average, with values generally between 64 and 272 milligrams per cup.

Because brewed coffee requires that the water is in contact with the grinds for a long time, this leads to a higher caffeine concentration (and sometimes an over-extracted taste).

Drip Coffee is the Most Popular

Drip coffee is perhaps the most popular form of brewed coffee, at least in the USA. This is the method used by Starbucks, Dunkin Donuts, McCafe as well as countless other restaurants.

Even K-cups are a type of drip brewed coffee.
