Taste as you go. After the bloom, take a sip of the liquid that's dripped through. It should be sweet and mild. After the second pour, it should be more intense but still balanced. If it's bitter early, your grind is too fine or your water's too hot. If it's sour, grind finer or pour slower. That feedback loop is your guide. When the final cup hits that sweet spot—bright but not sharp, full but not heavy—you've nailed it. That's your 'after'.

And when you pack up, you'll know the next event starts from a better place.
