Brewing guide

Good coffee is mostly patience.

You don't need much: a scale, a grinder, water just off the boil, and a timer. These are the ratios and timings we use at the roastery every day — starting points, not commandments. Adjust one variable at a time and trust your own cup.

Pour-over brewing: kettle pouring water into a dripper

Pour Over

Ratio
1:16 — 22 g coffee, 350 g water
Grind
Medium-fine, like table salt
Water
94 °C
Time
2:45–3:15

Bloom with 60 g of water for 40 seconds, then pour in slow spirals. If the cup tastes thin, grind finer; if it turns bitter, coarser. Our reference method for light roasts.

Espresso

Ratio
1:2 — 18 g in, 36 g out
Grind
Fine, adjusted daily
Water
93 °C
Time
26–30 s

Dial in with the roast rested at least ten days. Nightfall and Cerrado are built for this; light roasts want a slightly longer ratio (1:2.5) and a touch more heat.

Chemex

Ratio
1:15 — 40 g coffee, 600 g water
Grind
Medium-coarse
Water
94 °C
Time
4:00–4:30

The thick paper gives a very clean, tea-like cup — flattering to floral coffees like the Yirgacheffe. Rinse the filter well and keep the pour steady.

French Press

Ratio
1:14 — 30 g coffee, 420 g water
Grind
Coarse, like breadcrumbs
Water
95 °C
Time
4:00, then rest 4:00

After four minutes, stir the crust, skim the foam, and wait another four before pressing gently. The patience step is the whole trick — it drops the sediment.

AeroPress

Ratio
1:13 — 15 g coffee, 200 g water
Grind
Medium-fine
Water
90 °C
Time
1:30 + 30 s press

Forgiving, fast, and travel-proof. Slightly cooler water keeps it sweet. Inverted or upright both work; consistency matters more than doctrine.

Cold Brew

Ratio
1:8 — 100 g coffee, 800 g water
Grind
Very coarse
Water
Cold, filtered
Time
16–18 h in the fridge

Steep, strain through paper, and dilute to taste over ice. Chocolatey coffees — House Blend, Cerrado, Marcala — hold up best. Keeps a week refrigerated.

Three rules that outrank everything above

  1. Weigh everything. Scoops lie. A $20 scale improves coffee more than any brewer.
  2. Grind just before brewing. Ground coffee stales in minutes; whole beans keep for weeks.
  3. Use good water. Coffee is 98% water. If your tap water tastes off, so will the cup.
