Chemex Coffee: How to Brew a Clean, Sweet Cup at Home
If you love the clarity of a V60 but want something gentler and more forgiving, Chemex coffee deserves a place on your counter. The glass hourglass brewer looks beautiful on a café table, and it makes a cup that is bright, sweet and remarkably clean. In this guide, we walk you through how Chemex works, what you need, and a simple recipe you can repeat every morning.
What Is a Chemex and Why Does It Taste So Clean?
The Chemex was designed in 1941 by chemist Peter Schlumbohm. It is a pour-over brewer: hot water passes through ground coffee and a paper filter, then drips into the glass carafe below. What makes it special is the filter. Chemex filters are noticeably thicker than most other paper filters, so they catch more oils and fine particles.
The result is a cup with high clarity. Floral Ethiopian lots taste more floral, and fruity Kenyan coffees taste juicier. The trade-off is lighter body, so if you love a heavy, syrupy cup, French press or moka pot may suit you better. If you love tasting the details, Chemex is hard to beat.
Chemex vs V60: What Is the Difference?
Both are pour-over methods, but they behave differently. The V60 drains fast and rewards precise pouring. The Chemex drains more slowly because of the thick filter, which makes it more forgiving and better suited to brewing for two or three people. Think of the V60 as the sharp, technical option and the Chemex as the calm, social one.
What You Need
Keep the setup simple. You need a Chemex brewer, Chemex-compatible bonded filters, a gooseneck kettle, a scale with a timer, and freshly roasted whole beans. A burr grinder helps a lot, because an even grind is the biggest factor in a clean Chemex cup. If your cup tastes bitter or sour, our grind size and troubleshooting guides will help you adjust.
Choosing the Right Beans
Light to medium roasts shine in a Chemex. Washed Ethiopian and Kenyan coffees give you floral and citrus notes, while Colombian and Brazilian coffees give you caramel, nuts and chocolate. For your first few brews, a medium roast with balanced sweetness is a friendly place to start. Try to brew within a few weeks of the roast date for the best flavour.
The Basic Chemex Recipe
This recipe makes about two generous cups and uses a ratio of roughly 1:16, which means 1 gram of coffee for every 16 grams of water.
- Coffee: 30 g, ground medium-coarse (similar to coarse sea salt)
- Water: 480 g at 92–96°C (just off the boil)
- Total time: 4 to 4:45 minutes
Step by Step
- Prepare the filter. Fold the filter so the thick, three-layer side sits against the pouring spout. Place it in the Chemex and rinse it with hot water. This removes the papery taste and warms the glass. Pour the rinse water out.
- Add the coffee. Add 30 g of ground coffee and gently level the bed. Place the Chemex on the scale and zero it.
- Bloom (0:00). Pour 60 g of water, making sure all the grounds are wet. Wait 40 seconds. You will see the coffee bubble as it releases gas, which is a good sign of freshness.
- First pour (0:40). Pour slowly in small circles up to 250 g, staying away from the paper edges.
- Second pour (1:45). Pour gently up to 380 g.
- Final pour (2:30). Pour up to 480 g, then stop. Let the water drain through.
- Finish. The bed should be drained by around 4:00 to 4:45. Remove the filter, give the carafe a gentle swirl, and pour.
How to Adjust Your Chemex Brew
Your taste is the final judge. If the coffee tastes sour, thin or salty, it is probably under-extracted: grind a little finer or pour a little slower. If it tastes bitter, dry or harsh, it is probably over-extracted: grind a little coarser. Change only one variable at a time and write down the result. This is how a good routine compounds into a great cup.
If the water drains much faster than 4 minutes, go finer. If it stalls and takes more than 5 minutes, go coarser, because very fine particles can clog the thick filter.
Common Chemex Mistakes
The most common mistake is grinding too fine, which clogs the filter and gives a bitter cup. The second is skipping the rinse, which leaves a papery taste. The third is pouring water directly onto the paper wall, which lets water bypass the coffee. Pour in the centre and keep your movements slow and calm.
Serving Chemex Coffee in Saudi Arabia
A Chemex is made for sharing. On a cool Eastern Province evening, brew a full carafe for the family and serve it in small cups alongside Saudi dates. The sweetness of the dates complements the clean, fruity notes of a washed light roast beautifully. Serve it as it is, without milk or sugar, so you can taste what the farmer and the roaster worked on.
Final Thoughts
Chemex coffee is slow, simple and rewarding. With fresh beans, the right grind and a steady pour, you can brew a café-quality cup at home. Start with the recipe above, adjust one step at a time, and enjoy the ritual.
