What Is Filter Coffee?

Filter coffee is a brewing method where you pour hot water over coffee grounds and let the brew run into the pot through a filter. Standard coffee machines brew filtered coffee, and unlike the manual method, they heat the water from a reservoir before dripping it over the grounds.

Caffeine Content Comparison Filter Coffee to Other Brewing Methods

Remember that filter coffee has, on average, 145 mg of caffeine per 8-ounce cup; we’ll compare it to other methods below to see which method comes out on top.

Filter Coffee 145 mg per 8-ounce cup
French Press or Plunger Coffee 107.5 mg per 8-ounce cup
Percolated Coffee 200 mg per 8-ounce cup
Boiled (Turkish or Greek Coffee) 200 mg per 8-ounce cup

These are just average amounts of caffeine, but as you can see, filter coffee contains more and sometimes less than other brewing methods. It’s important to realize that more than the brewing method goes into determining the caffeine content in coffee. You have to consider the type of beans you use, how much ground coffee you use, and the brewing method.
