Brewing With Chemex: Coffee To Water Ratio Guide
Quick Answer
- A standard 6-cup Chemex usually makes about 30-35 oz of brewed coffee.
- The “how much coffee does a Chemex make” depends on the size of your brewer and how much water you start with.
- A good starting point for your coffee to water ratio is 1:15 to 1:17.
- That means for every gram of coffee, use 15 to 17 grams (or ml) of water.
- For a 6-cup Chemex, this often translates to around 50-60 grams of coffee.
- Don’t be afraid to tweak this ratio to find your sweet spot.
Key Terms and Definitions
- Chemex: A pour-over coffee brewer known for its elegant design and thick paper filters. It uses gravity to brew.
- Pour-over: A manual coffee brewing method where hot water is poured slowly over coffee grounds in a filter.
- Bloom: The initial stage of brewing where hot water hits fresh coffee grounds, releasing CO2. You’ll see them puff up.
- Extraction: The process of dissolving soluble compounds from coffee grounds into water. This is what makes coffee taste like coffee.
- Ratio: The proportion of coffee grounds to water used in brewing. Usually expressed as grams of coffee to grams/ml of water.
- Grind Size: Refers to how finely or coarsely the coffee beans are ground. For Chemex, it’s typically medium to medium-coarse.
- Total Dissolved Solids (TDS): The concentration of dissolved substances in brewed coffee, indicating strength.
- Brewing Vessel: The container used to hold the coffee grounds and water during brewing, like the Chemex itself.
- Water Temperature: The heat of the water used for brewing, a critical factor in extraction.
- Brew Time: The total duration from the first pour of water to the last drip of coffee.

How It Works
- The Chemex is a simple, elegant brewer. It’s essentially a glass carafe with a special spout.
- You place a thick, folded paper filter into the top cone.
- Rinse the filter with hot water. This gets rid of paper taste and preheats the brewer.
- Add your ground coffee to the filter.
- Slowly pour hot water over the grounds in stages.
- The water passes through the coffee, extracting flavor compounds.
- Gravity pulls the brewed coffee down into the Chemex carafe.
- The thick filter traps most of the coffee oils and sediment.
- The result is a clean, bright cup of coffee.
- You control almost everything: water temp, pour speed, and amount.
What Affects Your Chemex Coffee
- Coffee Beans: Freshness is king. Older beans lose aromatics and flavor. Roast level matters too.
- Grind Size: Too fine, and it’ll choke the filter, leading to bitterness. Too coarse, and water runs through too fast, resulting in weak coffee. Aim for medium-coarse, like sea salt.
- Water Quality: Tap water can have off-flavors. Filtered water is usually best. Avoid distilled water; it lacks minerals needed for good extraction.
- Water Temperature: Aim for 195-205°F (90-96°C). Too hot can scorch the grounds; too cool under-extracts.
- Coffee-to-Water Ratio: This is the big one. Too little coffee makes it weak. Too much makes it too strong or bitter.
- Pouring Technique: How you pour water affects extraction. Slow, steady circles are key. Avoid pouring directly down the sides.
- Brew Time: A typical Chemex brew takes about 3.5 to 4.5 minutes. Too fast or too slow can ruin the cup.
- Filter Type: Chemex filters are thick. They trap more oils and fines than other pour-over filters. Make sure you fold it correctly.
- Grinder Quality: A consistent grind is crucial. Blade grinders are inconsistent; burr grinders are the way to go.
- Preheating: A warm Chemex and mug help maintain brewing temperature.
- Agitation: Stirring the grounds or vigorous pouring can over-extract. Be gentle.
- Altitude: Water boils at a lower temperature at higher altitudes. You might need to adjust your water temp slightly.
Pros, Cons, and When It Matters
- Pro: Clean Cup: The thick filter makes for an exceptionally clean, bright cup. You taste the nuanced flavors of the bean.
- Con: Filter Cost: Those special Chemex filters aren’t free. They add up over time.
- Pro: Beautiful Design: Let’s be honest, it looks great on the counter. It’s a conversation starter.
- Con: Learning Curve: It takes practice to get a perfect pour. It’s not as foolproof as a drip machine.
- Pro: Full Control: You are the barista. You dial in the grind, temp, and pour.
- Con: Time Commitment: It’s a manual process. You need to be present for the whole brew.
- Pro: Great for Single Origin: If you love highlighting the unique flavors of a specific coffee bean, Chemex shines.
- Con: Can Be Delicate: Glass can break. Handle with care, especially when washing.
- Pro: Easy Cleanup: Toss the filter, rinse the carafe. Pretty simple.
- Con: Not Ideal for Large Crowds: Brewing multiple cups takes time. It’s best for 1-4 people at a sitting.
- Pro: Low Maintenance: No complex parts to break or descale.
- Con: Filter Folding: Getting the filter folded right can be a minor annoyance at first. Check the instructions.
Common Misconceptions
- Myth: Chemex makes weak coffee. Nope. That’s usually a grind or ratio issue, not the brewer itself.
- Myth: Any paper filter works. Not really. Chemex filters are designed for their specific brewer. Using others might affect flow rate and taste.
- Myth: You need fancy, expensive coffee. While good beans help, you can make a solid cup with decent quality coffee. Focus on freshness.
- Myth: Pouring fast is better. Quite the opposite. Slow, controlled pours allow for even extraction.
- Myth: Dark roasts are best for pour-over. While you can brew dark roasts, pour-over really shines with medium to light roasts, showcasing their complexity.
- Myth: You can use pre-ground coffee. You can, but it’s not ideal. Freshly ground coffee makes a huge difference.
- Myth: The Chemex size dictates the coffee amount. The size dictates the maximum amount of water you can brew. You can brew less.
- Myth: All pour-overs taste the same. Different brewers have different designs that affect flow and filtration, leading to subtle taste differences.
- Myth: The bloom is just for show. It’s crucial for degassing, which leads to more even extraction.
- Myth: You can’t make espresso-style coffee. Chemex is designed for filter coffee, not espresso. Different brewing methods entirely.
FAQ
Q: How much coffee does a Chemex make in ounces?
A: A 6-cup Chemex can brew around 30-35 ounces of coffee, depending on how much water you put in and how much is absorbed by the grounds.
Q: What’s the best coffee to water ratio for Chemex?
