Brew Science

Why this recipe

Surf Jam · DAK COFFEE ROASTERS
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 · 150ml + 75g ice
Poured over ice
150 ml of water drips onto 75 g of ice. It starts strong on purpose; the melting ice, 33% of the cup, brings it to drinking strength.
Grind · 53
Medium-coarse grind
Coarse sea salt. Naturals give up flavour fast, so it's set coarser; the dense bean pulls it back a little finer.
Dial in your grinder
Temp · 88°C
One steady heat
88° for every pour. Holding it level keeps every pour extracting at the same pace.
Bloom · 40s
Medium bloom
40 ml of water, then a 40-second wait. Escaping gas pushes water away; waiting it out lets the pours that follow soak in evenly.
Pour Structure · 3 pours
Bloom and two pours
Fewer, larger pours stir the bed more, for a heavier cup.
70 RPM · SPIRAL · 3.2 ML/S
A slower spin lands the water softly, keeping harsh notes out of the cup. Spiral pours reach the edges and stir the whole bed.

Coarser than most in this group. Soft beans extract fast, and a coarser grind keeps the cup clean.
