27g/27s Question

Dan Tochterman

quick clarification on this....

does the 27s start counting from the moment pre-infusion ends or from the moment the first drops hit the cup?

for example, i may end pre-infusion after 8 seconds, but the first drop may not hit the cup until 17s (if we are counting from 0, the moment the lever comes down).

Using the Acaia Lunar scale, the count starts when the first drops have hit the cup and the flow has actually started into the cup.

If after 8 seconds you raise the lever and it still takes 9 extra seconds before the first drops come out of your coffee puck, that means that your pre-infusion was 17 seconds. If the shot tastes wonderful, no problem. Is the dark spots are *very* dark and a bitter taste is dominant, you can for instance grind a tad coarser, or tamp a little less hard, or make sure your dose weight is correct.

ok, got it! that makes sense.
