Grind sizeis very important for cold brew. It changes how water flows through coffee. A coarse grindlets water pass slowly, making the coffee less bitter. A fine grindcan make coffee taste bitter and hard to filter.

- Medium grind = balanced flavor, might take longer

Grind Size Options
Coarse grindis the best choice for cold brew coffee. It looks like sea salt and allows slow water flow. This grind helps avoid bitterness and makes a smooth taste. It also prevents clogging in your coffee maker.
Medium grindis a bit finer than coarse. It extracts flavor faster but can cause slight bitterness if brewed too long. This grind works well for drip coffee but is less common for cold brew.
Fine grindis like table salt or sugar. It releases flavors quickly but can make cold brew cloudy and bitter. Fine grind can clog filters and cause over-extraction. Usually, it is not recommended for cold brew.
| Grind Size | Texture | Effect on Cold Brew | Best Use |
|---|---|---|---|
| Coarse | Like sea salt | Smooth, less bitter, slow extraction | Ideal for cold brew |
| Medium | Between coarse and fine | Faster extraction, risk of bitterness | Drip coffee, some cold brews |
| Fine | Like sugar | Quick extraction, bitter, cloudy | Not recommended for cold brew |
