What You’ll Need
- Chemex (6-cup or 8-cup is perfect)
- Chemex paper filter
- Fresh Lighthouse Roasters coffee
- Burr grinder
- Gooseneck kettle
- Digital scale
- Timer
- Hot water (just off boil, ~205°F)
Brew Ratio
- Coffee: 42g
- Water: 700g (a little under 25 oz)
- Grind: Medium-coarse (closer to kosher salt)
- Time: 4–5 minutes
Step-by-Step
1. Heat your water
Bring your water to a boil, then let it cool for about 30 seconds. Shoot for 205°F if you’re measuring.
2. Rinse your filter
Place the filter in the Chemex with the triple-fold facing the spout. Rinse thoroughly with hot water to get rid of any paper flavor and warm the vessel. Discard the rinse water.
3. Weigh and grind your coffee
Grind 42g of Lighthouse coffee to a medium-coarse consistency, think kosher salt or breadcrumbs.
4. Add coffee & tare your scale
Add the ground coffee to the filter. Tap to level the bed, place the Chemex on your scale, and tare to zero.
5. Bloom (0:00–0:45)
Start your timer and pour 100g of water evenly over the grounds to saturate them. Let it sit for 30–45 seconds to bloom. You should see a nice rise and gentle bubbling.
6. Main pour (0:45–2:00)
Pour slowly and steadily in concentric circles, adding water up to 700g total. Keep the water level about an inch below the top. Try to finish pouring by 2:00.
7. Let it draw down (2:00–4:30)
Let the water finish draining through the bed. Total brew time should land between 4:00 and 5:00 minutes. Adjust grind size if it's too fast or too slow.
8. Serve and enjoy
Remove the filter, give the Chemex a swirl, and pour. Expect a cup that's clean, bright, and balanced.
