Ratio 1:16.7
Grind Medium-coarse
Temperature 200–205°F

What You’ll Need
- Chemex brewer
- Chemex bonded filters
- 42g of freshly ground coffee
- 700ml of water heated to 200–205°F
- Gooseneck kettle (recommended)
- Scale and timer
Step-by-Step Instructions
- Boil your water and let it cool slightly to between 200–205°F.
- Place the filter in the Chemex with the triple-fold facing the spout.
- Rinse the filter with hot water to remove any paper taste, then discard the rinse water.
- Add your ground coffee — it should be a medium-coarse grind, similar to sea salt.
- Bloom the grounds by pouring just enough water to saturate them (about 70ml). Wait 30–45 seconds.
- Continue pouring in slow, concentric circles, keeping the water level comfortably below the top of the filter.
- Total brew time should be about 4 minutes for 700ml of water.
Tips for the Best Cup
- Always use freshly roasted, freshly ground coffee
- The grind size matters — too fine and your coffee will be bitter, too coarse and it will be weak
- Experiment with ratios to find your perfect strength
Enjoy your Chemex brew! It’s one of the cleanest, most nuanced ways to experience specialty coffee.
