Grind Size Changes Everything
The beans are only half the story. Grind size determines how fast water moves through your coffee, which controls extraction — the balance of flavor pulled from the grounds. Too coarse and your cup tastes thin and sour. Too fine and it turns bitter and over-extracted. Match the grind to your brewer, and everything else falls into place.
At ZenBellies, every coffee we roast is available in your chosen grind — from Extra Coarse all the way down to Fine — so you can order exactly what your setup needs.
The Brewer-to-Grind Table
| Brewer | Grind Size | What to Look For |
|---|---|---|
| French Press | Coarse | Chunky, like coarse sea salt. Keeps grounds out of your cup. |
| Chemex | Medium Coarse | Slightly finer than French Press. The thick Chemex filter needs the extra surface area. |
| Drip Machine (auto) | Medium | The universal setting. Think table salt texture. |
| Pour Over (V60, Kalita) | Medium Fine | A touch finer than drip for a cleaner, more controlled brew. |
| AeroPress | Medium to Fine | Flexible by design — medium for a longer steep, fine for a quicker espresso-style shot. |
| Moka Pot | Fine | Close to espresso. Pressurized brewing needs fine grounds for proper resistance. |
| Cold Brew | Extra Coarse | Long steep time (12–24 hrs) means coarser is better — prevents bitterness. |
Already Using Pre-Ground Coffee?
Pre-ground works beautifully when you order to match your brewer. The key is freshness — pre-ground coffee oxidizes faster than whole bean, so we roast and grind your order on demand. If you brew with a drip machine most days and occasionally use an AeroPress, we'd recommend ordering Medium for drip and keeping a small bag of Medium Fine on hand for AeroPress sessions.
How to Adjust for Taste
Grind charts are your starting point, not a hard rule. Use this as your quick dial:
- Cup tastes sour, weak, or under-developed? Go one step finer. You need more extraction.
- Cup tastes bitter, harsh, or dry? Go one step coarser. You're over-extracting.
- Cup tastes balanced, sweet, and smooth? You found your grind. Stick with it.
Small changes make a big difference. One grind step at a time is all it takes.
