Brewing · Pour-over

How to brew a great V60

Five levers, in order — beans, grind, water, ratio, and the bloom. We explain the science instead of assuming it, so you understand why, not just what. Scroll to brew.

01

What pour-over actually is

Hot water flows oncethrough fresh grounds and a paper filter. The paper holds back oils and the finest particles — that's why a V60 tastes so clean and bright. You control everything, with just five levers. We'll walk through them in order.

The science: Filter coffee extracts solubles — water dissolves flavour from the bean. How much it dissolves (the extraction) decides sour ↔ balanced ↔ bitter.

02

Fresh beans, stored right

Freshly roasted isn't the same as ready. Coffee degasses CO₂ for days after roasting; brew too early and the gas pushes water away, extracting unevenly. Filter coffee usually tastes best 7–21 days after the roast date. The four enemies: oxygen, light, heat, moisture → keep it airtight, dark, cool. And grind just before brewing.

The science: Staling is oxidation of the aromatic oils. A bag's one-way valve lets CO₂ out but no O₂ in.

03

Grind: size and consistency

For V60 you want medium-fine — like coarse sand (~650 µm). But consistency matters more than size. Too many fines (dust) → over-extracted and a clogged filter (bitter). Too many boulders→ under-extracted (sour, thin). A burr grinder makes even particles; a blade chopper makes random sizes → you taste sour and bitter at once.

04

Water is the main ingredient

Coffee is 98 % water— it's the ingredient, not just the vehicle. Two things: temperature 90–96 °C (≈ 93 for V60) — hotter extracts more (bitter risk), cooler less (sour risk); and chemistry — water needs some mineral content to dissolve flavour. Too soft (distilled) → flat and sour; too hard → chalky and muted.

The science: Magnesium grabs fruit/sweetness aromatics especially well; bicarbonate buffers acidity. Aim ~150 mg/L hardness, ~40 mg/L buffer.

05

The ratio

The brew ratio is coffee to water. The standard: 1 : 16 to 1 : 17— about 60 g per litre (the "golden cup"). Stronger (1:15) = more intense; lighter (1:17) = more tea-like. Our recipe: 15 g coffee → 250 g water (≈ 1 : 16.7). Always weigh, never scoop — scoops vary ±30 %.

The science: Ratio sets strength (TDS ~1.2–1.35 %); grind/time/temp set extraction (~18–22 % of the mass dissolved). Two different dials.

06

The bloom

Pour just ~2× the coffee weight first, then wait 30–45 seconds. Fresh coffee swells and foams — that's the CO₂ escaping. Only after the bloom does the bed take water evenly. Then pour in slow spirals to your target, avoiding agitation, and let it draw down.

Medium-fine, like coarse sand.

  1. 0:00Bloom — 45 g in a spiral, saturate all grounds
  2. 0:45Pour 1 — slow spiral to 150 g total
  3. 1:30Pour 2 — continue to 250 g, no agitation
  4. 3:00Draw-down — bed flat, even surface

Aim for 2:45–3:15 total. Runs fast → grind finer. Runs slow → grind coarser.
