Brewing a great cup of coffee isn’t just about the beans — the grind size you use makes a huge difference too. Each brewing method requires a specific grind size to bring out the best flavor in your coffee.
In this guide, we’ll walk you through 5 popular coffee brewing methods and show you exactly which grind size suits each one best — so you can enjoy barista-quality coffee at home.
☕ 1. French Press
Grind size: Coarse (like sea salt)
A French press makes full-bodied coffee. Coarse grounds help prevent fine particles from slipping through the mesh filter and over-extracting.
Coffee-to-water ratio: 1:15
Brew time: ~4 minutes
Tip: Gently press the plunger down to avoid bitterness from over-agitation.
☕ 2. Drip Coffee (Pour Over / Coffee Maker)
Grind size: Medium (like granulated sugar)
Perfect for V60, Chemex, or standard drip coffee makers. A medium grind allows water to flow evenly, extracting a balanced flavor.
Ratio: 1:15–1:17
Brew time: 2.5–4 minutes
Tip: Rinse the paper filter before brewing to remove any papery taste and warm the brewer.
☕ 3. Espresso
Grind size: Fine (like table salt)
Espresso machines extract under pressure in 25–30 seconds. Fine grinds increase surface area, creating a rich, intense shot.
Ratio: 1:2
Brew time: 25–30 seconds
Tip: Small adjustments in grind size make a big impact on taste — dial in carefully.
☕ 4. Moka Pot
Grind size: Medium-fine (between espresso and drip)
The Moka pot brews strong coffee on the stovetop. A medium-fine grind provides good resistance for pressure and prevents over-extraction.
Ratio: Fill filter basket fully without tamping
Brew time: 3–5 minutes
Tip: Do not tamp the coffee, and remove from heat once coffee reaches top chamber.
☕ 5. Cold Brew
Grind size: Coarse (like rough sand)
Cold brew is brewed slowly over hours. Coarse grinds prevent bitterness and yield a clean, smooth cup.
Ratio: 1:8 (concentrate) or 1:15 (ready-to-drink)
Brew time: 12–24 hours (in fridge)
Tip: Double filter the coffee for extra clarity.
How to Tell If Your Grind Size Is Right?
- Brewing too fast / coffee tastes sour? Your grind is too coarse — try a finer grind.
- Brewing too slow / coffee tastes bitter? Your grind is too fine — adjust to a coarser setting.
- Coffee tastes weak or too intense? Check the balance between grind size and brew time — they work hand in hand.
