Coffee experiments press

The French Press (Press Pot, or Cafetiere) is a full immersion, non-filtered brew method. The resulting coffee tends to be full bodied with a heavier mouth-feel and an oilier finish than methods that use a paper filter.

    5. After the 4 min of immersion time, give the pot a quick stir then plunge firmly but slowly. It should take around 20s to reach the bottom.

    Coffee experiments decant press

    6. Quickly decant brew into warmed drinking vessel. Contrary to popular belief, French Press coffee keeps brewing after plunging so it's important to decant before too many bitter flavors are extracted.
