Chemex vs. French Press: Which One Brews the Best Coffee?

Chemex vs. French Press: Which One Brews the Best Coffee?

Manual coffee-making methods are gaining popularity as more people say goodbye to their traditional drip coffee maker systems in search of more refined coffee experience, that’s why I thought I would have a very serious look at what brews better coffee: Chemex vs French Press? Let’s examine.

Brew Time: Brew Richer Java

Most coffee drinkers want a richer Java and have grown tired of the 3-lb. bag of ground coffee beans that start to lose its flavor the moment the bag is opened. I mean honestly, does that air vent on the outside of the bag serve any purpose at all?

Whatever the reason, more people are turning to immersion brewing methods like Chemex and French Press to extract more flavor from fresh coffee beans and gain greater control over the brewing process.

In this article, I will discuss both the Chemex and French Press methods of brewing coffee to help you decide if you’re ready to take the leap into the land of coffee sophistication. I stand at this crossroads with you having recently decided to ditch my drip brewer and take my love for coffee on the next level by making my own cups of coffee with these brewing methods.

I’ll provide a brief snapshot of the method, tell you what you need to make it happen, and give you a step-by-step walkthrough the brewing process to help set you up for success. By the end, you should know what method is right for you, and hopefully, you’ll be jazzed about your next cup of joe.

Here we go!


I’m starting with the Chemex filters method because I find it most intriguing. Plus, it’s pretty.

A Brief History

The Chemex method was developed by Dr. Peter J. Schlumbohm, Ph.D., a doctor of chemistry in 1941 (that’s him below). It’s not shocking, then, that he used an Erlenmeyer flask in creating the coffee-making device. Take a look:

He chose the beaker-like glass because as a chemist, he knew he needed a non-porous labware that would impart no flavor of its own when extracting the flavor and caffeine from the coffee beans.

Now fast-forward to 2017; here is what the Chemex coffee maker looks like today in four different sizes:

Chemex carafes like these cost between $20-$50 and, you guessed it, are easy to clean and maintain.

How to Use a Chemex Coffee Maker

You will need:

  • A Chemex coffee carafe
  • Chemex-branded coffee filters which are 20-30% thicker than your typical paper filter
  • Coffee beans
  • Grinder (many online reviewers recommend a burr grinder)
  • Tea kettle (or something similar) to boil water
  • Spoon

Step One:

Boil the water based on the number of cups you plan to brew, plus some water to prepare the carafe. A common ratio when manually brewing coffee is 1:15 which translates to 15 grams of ground coffee per every 225 grams of water. You can adjust this ratio as you see fit.

Step Two:

Prepare the Chemex by putting the filter in the top with the multiple folds towards the spout. You want to soak the filter with that extra hot water to prepare the carafe for the brewing process and to rinse any residual paper flavor from the filter. Discard the water.

Step Three:

Measure one tablespoon of whole beans per cup of water or if you use a scale, weigh out 8 grams of coffee for every five-ounce cup.

Step Four:

Grind your beans to a medium coarseness. Your coffee grounds should look like this:

Step Five:

Place your grinds into the filter and saturate the grounds until they are wet, but don’t allow the water to drip yet, and let it stand for one minute. This part is called “letting it bloom” with only fresh beans producing a wonderful aroma during this stage. Stir the grounds to make sure there are no dry clumps.

Step Six:

After one minute, pour the rest of the water over the coffee starting with a “wiggle pour” across the center, then transitioning into a spiral motion from the outermost edge of the filter to its center. Allow the water to drip down and avoid rushing the pour; you don’t want to fill the Chemex up to its top. If you want, you can use a scale to ensure you are using enough water.

Step Seven:

Once the water has finished filtering through the grounds, remove the filter and discard it, pour, and enjoy your coffee. To keep it warm, pour the remaining coffee into a thermos or insulated carafe.

According to online reviewers, a Chemex cup of coffee takes about 5-6 minutes to brew, and the resulting java is rich and clean with no sediments to greet you at the bottom of your cup. Compared to the French Press, the brewing process is a little more involved, but the Chemex clean-up is a breeze.

Chemex Conclusion:

Thanks to its filter, the Chemex cup of coffee is clean, bright, and rich. This pour-over immersion method allows anyone with five minutes to spare to transform beans into a coffee experience. Online reviewers credit the blooming process for giving each brew its distinct flavor, and they enjoy the chance to customize each cup. I don’t know about you, but I can’t wait to try out this method to customize my own.

French Press

The French Press method is the full immersion way to make coffee. It was first developed in France in 1852 by Frenchmen Mayer and Delforge and was later improved upon by Italians Attilio Calimani and Giulio Moneta in 1929. The concept is simple, to completely immerse the coffee grounds, or “steep” the coffee, and then use a metal plunger, or press, to separate the grounds from the coffee. The brew time is quick and most serious coffee drinkers use this as their weekend go-to method for brewing fresh coffee.

French Press coffee is known for its strong, bold flavor and full body that results from the steeping process. Unlike the Chemex or drip variety, a French Press doesn’t use a paper filter and instead relies on a metal mesh filter to separate the grounds from the coffee to brew a strong, robust cup of coffee.

How to Use a French Press Coffee Maker

You will need:

  • French Press carafe
  • Burr grinder
  • Coffee beans
  • Tea kettle (or something similar) to boil water
  • Spoon

You want to prepare the French Press carafe for the coffee so it is warm and ready to receive the brew, the same way you prepare a Chemex carafe. If it isn’t, the glass will absorb all the heat from the coffee and alter its flavor.

Step One:

Boil the water you need based on the number of cups you plan to brew, plus extra to warm the carafe. A common ratio when manually brewing coffee is 1:15 which translates to 15 grams of ground coffee per every 225 grams of water. You can adjust based on taste preferences from this starting point. Pour the extra water into the carafe, swirl it around so it touches all sides, and discard the water before brewing.

Step Two:

Grind your coffee with a burr grinder until it is coarse, like granules instead of sand. It should look like this:

You want the grind to be big enough that you can filter it out using the French Press filter. If the grind is too fine, like the kind used in traditional brewing methods, the granules will slip through the filter and end up in the bottom of your cup.

Your beans should be fresh and you need to only grind as much as you plan to brew. The beans release oils and flavors during the grinding process so the freshest grind produces the best cup of coffee. When allowed to sit, even under ideal conditions, grounds can lose the oils and flavors and cause a bitter brew.

Step Thre

Ideally, you want the temperature of your water to be 90 degrees Celsius before adding it to your French Press carafe. Once your water reaches a boil, you can usually achieve this temperature by removing it from the heat and letting it sit for a minute.

Step Four

Add your prepared grounds to the French Press and slowly begin to add the water, taking care to first saturate the grounds before adding the rest (about halfway). You should aim to add double the grams of water as there is coffee for maximum flavor extraction (or bloom, just as in the Chemex method). Wait one minute to allow a crust to form on the top of the brew.

Step Five

Break the crust by stirring the saturated mix gently for 30 seconds and then add the remaining water. Let the coffee steep for four minutes and then press down slowly on the French Press plunger to separate the grounds from the brew. It should look something like this:

Do you see how the grounds are pushed to the bottom of the French Press? Ideally, the plunger captures all the grounds as it slowly is pushed to the bottom. Realistically, some are left behind and end up at the bottom of your cup.

For all you visual learners out there, here’s a quick video explaining the process from Stumptown:

French Press Conclusion:

This method of brewing is perfect for those that like a strong, full-bodied, and flavorful cup of coffee. It doesn’t require any filters which save money and is better for the environment, but you will be greeted by grounds at the bottom of your cup as a result. For most online reviewers, these grounds aren’t a big deal and are a small price to pay for a rich cup of coffee.

The metal filter needs some extra TLC to make sure grinds from your previous cup of coffee don’t impart an unpleasant flavor on your next one. After each brew, you want to thoroughly clean both the press and the filter removing leftover grinds and residue to ensure an authentic brewing experience each time.

Which One is Right for You?

I hope this information helped you decide which manual press coffee method to try. The Chemex may take a bit more effort and time, but for those who enjoy a lighter, cleaner brew it might be the one for you. For those that are pressed for time (pun intended), you may appreciate the convenience of the French Press as long as you have time to clean it later. Either way, both methods will help elevate your daily ritual to something more than just a cup of joe.

FAQs About Chemex vs French Press

Is French press coffee good for health?

Due to the way of brewing, which leaves cafestol pass through the filters, French press coffee increases the bad cholesterol levels, which means it’s not good for those who suffer from cholesterol.

Why is my French press coffee so bitter?

Press pots use a coarser grind, so a bitter coffee means that the coffee is good and strong. Sometimes it takes time to get used to the grinder, so be patient while discovering the perfect cup of coffee with the French press method.

Does Chemex coffee taste better than French press?

Chemex coffee definitely is superior to French press because of the borosilicate glass construction that does not alter the coffee flavor of the beans.
