One clear way forward

Built from your coffee, goal, and stated setup — then science-gated before it reaches you.

Bright & Layered

1:16.5 · 15g · 248g water
Strategy: protect clarity and florals while giving this light washed coffee enough energy to reach sweetness. Setup: Hario V60 · Comandante C40.
1
Bloom — 45g, 40s
Wet evenly, then swirl once to settle the bed.
A generous, even bloom degasses this young coffee so extraction stays even and sweet — uneven blooms are where clarity is lost.
2
First pour — to 150g
Slow spiral, keep the water shallow.
Gentle, shallow pours limit agitation — the enemy of a delicate washed coffee — protecting against astringency.
3
Second pour — to 248g
Finish by 1:45, aim to drawdown ~2:30.
A brisk total time keeps the cup bright and prevents the tail-end bitterness that would bury the florals.
4
Swirl & serve
Swirl the carafe, rest 60s, taste.
A short rest lets volatile aromatics settle into the cup — the difference between smelling the fruit and tasting it.

Tasting notes

Bright and clean, but a little hollow in the middle — the sweetness drops off before the finish. Fruit is there but faint.

The diagnosis

loops back to radar ↑

"That hollow middle is under-extraction — you're getting the bright top notes but not the sweetness underneath. Two small moves fix it."

Grind two clicks finer
Slows the flow and pulls more sweetness through the middle.
Lower your agitation
Gentler pours stop the astringency that's thinning the body.
Nudge water to 94°C
A touch hotter helps sweetness develop without adding harshness.
