How to Make Chemex Coffee Without a Scale: Measuring by Volume

You love your Chemex but don't own a kitchen scale? No problem. While weighing your coffee and water is the most precise way to brew, you can absolutely make a fantastic cup of Chemex coffee using simple volume measurements. This guide will show you exactly how to measure coffee without a scale, using tablespoons, scoops, and standard cups.

Whether you're camping, traveling, or just haven't invested in a scale yet, these methods will help you achieve a balanced, flavorful brew. We'll cover the golden ratios, practical measuring tips, and how to adjust to your taste. By the end, you'll be brewing consistently great Chemex coffee with nothing more than your everyday kitchen tools.

Understanding the Golden Ratio for Chemex

The golden ratio for Chemex brewing is typically 1:15 to 1:17 (coffee to water). That means for every gram of coffee, you use 15 to 17 grams (or milliliters) of water. Without a scale, we need to translate this into volume. A standard tablespoon of ground coffee weighs approximately 5 to 7 grams, depending on the grind size and bean density. For a medium grind suitable for Chemex, 1 tablespoon is roughly 5 grams.

Using this approximation, a 1:16 ratio (a good middle ground) would require about 3.2 tablespoons of coffee per 500 ml (about 2 cups) of water. For a full 8-cup Chemex (which holds about 1.3 liters of water), you'd need around 8-9 tablespoons. Keep in mind that these are estimates, and you may need to adjust based on your personal taste and the specific coffee you're using.

• 1 tablespoon ≈ 5-7 grams of coffee (medium grind)
• 1 cup (8 oz) ≈ 240 ml of water
• Start with a 1:16 ratio and adjust to taste

Measuring Coffee by Volume: Tools and Tips

The easiest way to measure coffee without a scale is to use a standard tablespoon. Level tablespoons are more accurate than heaping ones. For a single cup (8 oz / 240 ml) of Chemex coffee, you'll need about 2 level tablespoons of ground coffee. For two cups, use 4 tablespoons, and so on. If you have a coffee scoop, note that most scoops are about 2 tablespoons (10 grams). So one scoop per cup is a good rule of thumb.

For even more convenience, consider using a dedicated measuring scoop that matches your Chemex size. For example, the Eight Cup ChemAerTM CHEMEX® comes with a built-in aerating screen and is designed for the 8-cup model, making it easy to brew large batches. While it doesn't come with a scoop, you can use a standard 2-tablespoon scoop to measure. Alternatively, the Six Cup Gold Glass Handle Set includes a glass handle and is perfect for those who prefer the classic look; you can measure your coffee with a regular tablespoon.

• Use a level tablespoon for consistency
• A standard coffee scoop = 2 tablespoons = ~10 grams
• Invest in a dedicated Chemex scoop if you brew often

Step-by-Step: Brewing Chemex Without a Scale

Start by boiling your water and letting it cool for about 30 seconds to reach the ideal temperature (around 200°F / 93°C). While the water heats, place a Chemex filter in the top of your brewer and rinse it with hot water to remove any paper taste and warm the glass. Discard the rinse water.

Now, measure your coffee. For a 6-cup Chemex (about 750 ml of water), you'll need approximately 6 tablespoons (or 3 scoops) of ground coffee. Add the coffee to the filter and give it a gentle shake to level the bed. Begin pouring water in a slow, circular motion, starting from the center and moving outward. Use about twice the weight of coffee in water for the bloom (e.g., 60 ml for 30 grams of coffee) and let it sit for 30-45 seconds. Then continue pouring in stages until you reach the desired volume.

• Rinse the filter first to preheat and remove paper taste
• Bloom with a small amount of water and wait 30-45 seconds
• Pour in a steady spiral to ensure even extraction

Adjusting to Taste and Common Pitfalls

Without a scale, you may find your coffee is too strong or too weak. If it's too strong (bitter), add a little more water or use slightly less coffee next time. If it's too weak (sour), use a bit more coffee or grind finer. Keep notes on how many tablespoons you used and how it tasted. Over time, you'll dial in your perfect ratio.

One common pitfall is using a heaping tablespoon, which can vary wildly. Always level your spoon with a knife for consistency. Also, be aware that different coffee beans have different densities; a light roast is denser than a dark roast, so a tablespoon of light roast weighs more. If you're using a particularly light or dark roast, you may need to adjust by a teaspoon or two.

• Level your tablespoons for accuracy
• Adjust based on roast: light roasts may need slightly more coffee
• Keep a brewing journal to track your measurements

When You Need Precision: Consider a Scale or a Cleaner

While volume measuring works well, if you become a serious home barista, you might want to invest in a digital scale for ultimate consistency. But remember, even without one, you can brew a great cup. To keep your Chemex in top condition, regular cleaning is essential. Over time, coffee oils can build up and affect the taste of your brew. Using a dedicated cleaner like the CHEMEX® Automatic Coffeemaker Cleaner will remove stubborn stains and odors, ensuring your coffee always tastes fresh. This is especially important if you brew without a scale and rely on your senses—a clean brewer makes a difference.

• Clean your Chemex regularly to avoid oil buildup
• Use a gentle, non-abrasive cleaner
• Rinse thoroughly after cleaning

Brewing Chemex coffee without a scale is absolutely doable and can yield delicious results. By using volume measurements like tablespoons and understanding the golden ratio, you can enjoy a consistent cup every time. Remember to adjust to your taste and keep your equipment clean.
