Step 5

Taste it

Most of the time it will be right first try. Sometimes it will need adjustment.All you need to decide is:
  1. Is it too sour, like lemon. In this case you need to extract more.
  2. Is OK, you dont need to change anything. Some refer to this as the sweet spot, but coffee doesnt actually contain sugar so think of this as the calm between too sour and too bitter.
  3. Is it too bitter. All coffee is bitter to some extent but you can reduce the bitterness by extracting less.
