Brew Method Guide

Espresso

14–20g dose ~1:2 ratio

High-pressure extraction forces water through finely ground coffee in 25–30 seconds, producing a concentrated shot with a rich crema.

Best with: 100, 75 – the intensity complements darker, full-bodied roasts.

~70% caffeine extraction

Pour Over / Drip

12–18g dose ~1:16 ratio

Gravity pulls water through a bed of medium-ground coffee over 3–4 minutes. Clean, clear cup with nuanced flavour.

Best with: All blends – showcases each blend's distinct character beautifully.

~90% caffeine extraction

French Press

18–25g dose ~1:15 ratio

Full immersion brewing with a coarse grind for 4 minutes. Produces a rich, full-bodied cup with natural oils.

Best with: 100, 50 – the heavy body pairs well with medium to full caffeine.

~90% caffeine extraction

AeroPress

12–18g dose ~1:15 ratio

A pressure-and-immersion hybrid. Versatile and forgiving – steep 1–2 minutes then press through a paper filter.

Best with: 50, 25 – great for experimenting with lighter caffeine levels.

~80% caffeine extraction

Moka Pot

12–16g dose ~1:10 ratio

Stovetop pressure brewer. Steam pushes water up through fine-medium grounds, producing a strong, espresso-style cup.

Best with: 100, 75 – stands up to milk and produces a punchy drink.

~80% caffeine extraction

Cold Brew

20–30g dose ~1:8 ratio

Coarse grounds steeped in cold water for 12–24 hours. Smooth, low-acid concentrate that's diluted to taste.

Best with: 100, 50 – the long steep brings out chocolate and caramel notes.

~65% caffeine extraction

Drip Bag

~10g pre-portioned ~1:15 ratio

Single-serve pour-over in a convenient filter bag. Hook over your mug, pour hot water, and steep for 3–4 minutes.

Best with: Any blend – perfect for travel, the office, or a quick cup anywhere.

Why Ratio Matters

Caffeine is highly water-soluble and dissolves within the first 30 seconds of brewing. The limiting factor isn’t temperature or pressure – it’s how much water contacts the coffee.

Espresso uses roughly 36mL of water per 18g of coffee (1:2). That’s concentrated, but the small volume only extracts about 70% of the available caffeine. Pour over uses around 240mL per 15g (1:16) – more dilute, but the greater water volume extracts up to 90%.

This is why espresso feels stronger per sip, but a full cup of filter coffee delivers more total caffeine. Cold brew compensates for its low water temperature with 6–7 hours of contact time, achieving high extraction despite the cold.
