Grind 54 · 91 °C · 50 s · 3:00–4:00
Calculated by BrewMind's AI from this bean's altitude, process and roast, then checked against physical limits before you saw it.
Fermented flavours turn boozy and sharp when pushed, so heat and stirring are held back to keep the fruit clean. It is a dense bean, slow to give up flavour, so it is set to draw out its sweetness.
The decisions
Coarse sea salt. Fermented beans give up flavour fast, so it's set coarser; the dense bean pulls it back a little finer.
Dial in your grinder →91 °C for the bloom, 85 °C after. Hotter turns fermented fruit boozy, so 91 °C is its limit.
45 ml of water, then a 50-second wait. Escaping gas pushes water away; waiting it out lets the pours that follow soak in evenly.
Fewer, larger pours stir the bed more, for a heavier cup.
45 → 135 → 225 ml
Spiral pours reach the edges and stir the whole bed.
