Brew Science

Why this recipe

牙买加蓝山一号 · 蓝山一号
Extraction Strategy
Body first

This bean's sweetness lives in its texture, so weight and sweetness are chosen before clarity. It is a dense bean, slow to give up flavour, so it is set to draw out its sweetness.

The Decisions
Drip on Ice · 140ml + 85g ice
Poured over ice
140 ml of water drips onto 85 g of ice. It starts strong on purpose; the melting ice, 38% of the cup, brings it to drinking strength.
Grind · 62
Coarse grind
Raw sugar. Dense beans give up flavour slowly, so it's set a little finer.
Dial in your grinder
Temp · 89→85°C
A clear step down
89° to start, then 87° and 85°. Heat opens the grounds early; stepping down keeps the finish sweet, not bitter.
Bloom · 37s
Short bloom
40 ml of water, then a 37-second wait. A short wait is enough before the next pour.
Pour Structure · 3 pours
Bloom and two pours
More of the water goes in early, while flavour comes out fastest. Fewer, larger pours stir the bed more, for a heavier cup.
78 RPM · SPIRAL · 3.3 ML/S
A faster spin stirs the bed harder, so the cup comes out full and even. Spiral pours reach the edges and stir the whole bed.
