Dark roast has a bad reputation it doesn't deserve. Most “bitter” dark roast isn't bitter because of the roast — it's bitter because of stale beans, water that's too hot, or a grind that's too fine for the method. Fix those three things and a good dark roast tastes like toffee and cocoa, not like an ashtray.
Rule 1: Grind right before you brew
Whole beans hold their aroma for weeks; ground coffee starts fading in minutes. Grind only what you're about to brew. If you take one thing from this post, make it this.
Rule 2: Back off the water temperature
Boiling water scorches dark roasts and drags out the harsh, roasty edge. Aim for 91–94°C (195–201°F) — in practice, take your kettle off the boil and wait 30–45 seconds before pouring.
Pour-over
- Medium grind — like coarse sand
- 1:16 ratio (25g coffee to 400g water)
- Total brew time around 3 minutes. If it tastes harsh, grind coarser.
Espresso
- Fine grind, 1:2 ratio (18g in, 36g out)
- Pull slightly long — 28–32 seconds. Dark roasts extract fast, so a touch coarser than you'd grind a light roast usually lands better.
French press
- Coarse grind — like breadcrumbs
- 1:15 ratio, 4 minutes steep
- Don't plunge hard; press slowly and pour immediately so it doesn't keep extracting in the carafe.
The freshness part we handle
Everything above assumes fresh beans — and that's the part you can't fix with technique. That's why we roast every bag within 48 hours of your order and print the roast date on it. Start with fresh beans, grind at the last minute, keep the water off the boil, and dark roast stops being “strong and bitter” and starts being what it should have been all along.
