What you will need;
What we Recommend;
Coarse grind Coffee grinder
Water, just off boil
1. Prep and Rinse Filter
Place your filter so that three layers cover the Chemex spout. Preheat your Chemex and filter with hot water, while at the same time rinsing your paper Chemex filter. Discard this water once done.
2. Grind and Add Coffee
Grind your coffee so you have about 3-4 tablespoons of course grind to add into your Chemex where your filter is place. Centre the coffee in your brewer and zero out your scales.
3. Wet the Grounds
Start your timer and start to add hot water, until all of the grounds are wet, approximately 150 grams.. Gentle stir to ensure there are no dry clumps with your stirrer. Leave for about 30 seconds.
4. Add more Hot Water
45 seconds in, start your second main pour. Do this in a slow circular movement until the volume reaches about a finger tip from the top of the Chemex rim, approximately 450 grams.
Allow water to lower and then add the remaining water, approximately 700 grams.
5. Let it Brew
Allow the coffee to drain through the filter, which should be about 4 minutes.
Then lift the filter carefully out of the Chemex, allowing it to hover if you need a little more volume, otherwise completely taking it out and placing in the bin, or sink if you are going to reuse the grind for other purposes.
Step 6. Enjoy
Swirl around the Chemex a little and serve up a quality Specialty Coffee brew with the Chemex.

There are both wooden and glass handle Chemex Coffee Makers. Which is better? It all comes down to personal preferences, both will brew the same coffee.
Wooden handles are generally seen as a better looking design, and can go really well on display in your kitchen, while glass handles are much easier when it comes to cleaning, as you do not need to un tie and take the handle off.

Your local Specialty coffee shop is also an idea, however, you will generally find yourself with a higher retail price to pay.

What Water Ratio For Chemex Coffee Maker?
If you are a beginner with Chemex brewing methods, we would recommend starting with a 1:15 coffee to water ratio.
In other words, for every 1 gram of coffee, add 15 grams of water, which converts to about 3 tablespoon of coffee for every 1 cup of water. Experiment from there to find the perfect ratio for you.
What Grind Size For Chemex Coffee Maker?
You may have read and/or heard that some prefer a coarse grind, while others prefer a fine grind.
We feel it all comes down to personal preference, what works for you may not for others, what taste good to you, may not for others.
The grind size can also come down to your serving sizes, however, generally speaking, if you are unsure where to start, then with a 3 cup Chemex, try a finer grind.
If you are using an 8 cup or larger Chemex then try a coarse grind, similar to that as a French Press grind.
Ultimately, if your coffee brews too fast and taste weak, then you will need to use a finer grind, however, if your coffee gets clogged and is not filtering through, then use a coarser grind. Your brew should be about 4 minutes long.
And do not forget the most important part, you need to ensure you are using a quality burr grinder to have consistent grinds.
You will never be able to get your brew right and it will be hard to adjust to your personal preference every time you brew with your Chemex.
Need a Burr Grinder? We suggest something like the Hunt’s Brother’s Coffee Grinder which you can find over on Amazon.
What is the Difference Between Chemex Coffee Maker and Drip Coffee?
A question we get asked all the time, what is the difference between Chemex and Drip Coffee?
Yes the Chemex does brew coffee using the infusion method which is similar to other drip coffee methods, however the big difference is the filters used with the Chemex.
Chemex filters are about 25% thicker than drip coffee filters, which helps regulate the flow of coffee while removing much of the coffee’s oils and body.
Resulting in the water flowing through much slower and therefore, many suggesting a better flavour develops.
Can You Use The Chemex Without Digital Scales?
Another question that we seem to get asked regularly, and even though we recommend that you should use scales when brewing with a Chemex, in short you can get away without the scales.
The Chemex brew will however be very hard to get precise and overall could hinder your finished brew.
By using scales, it will allow you to measure your coffee and water amounts, therefore, actually saving you time.
Also if you are a beginner with Chemex brewing methods then scales will definitely be missed.
Overall, if you are into your Specialty Coffee and brewing, then digital scales are a perfect investment as you can use these with many other brewing methods such as the Hario V60.
You can find a perfect set of scales like the Coffee Gator Digital Scale with Timer which we found over on Amazon, however, have a little search around as Amazon has many options available for all budgets.
Chemex Vs Aeropress
You have probably heard of the Aeropress right? Another iconic method of Specialty Coffee brewing, however, do not get confused, this brewing method is very different from the Chemex.
So what is better, the Chemex or the Aeropress?
Firstly, both of these these are manual brewing methods, meaning you can use this specialty coffee making method at home, while always customising as you go.
Whether that’s the beans you use or the grind size you make, you can forever change it up and experiment.
Secondly, the taste. We love the taste from both brewing methods, however, it is important to note that the Chemex and Aeropress share very different taste from each other, all due to the extraction time and brewing techniques.
When using the Aeropress, it requires pressure, rather than dripping through.
Therefore, the Aeropress generally results in a stronger more bold espresso brew, where as the Chemex will create brews a much more crisp and rich brew.
So our final thoughts? Well both brewing methods are just as good as each other in their own little ways, we would recommend brewing Specialty Coffee with both methods.
If you are looking for that clean brew, then both methods are going to provide you that, however, if you are someone on the go, or always travelling, then the Aeropress is much more portable compared to the glass Chemex.
Or if you need a stronger Specialty brew, then go with the Aeropress, or if you need a richer and more complex Specialty brew, then the Chemex is your go to.
How to Clean Chemex?
Surprisingly for some, the Chemex can actually be relatively difficult to clean, however, due to its design and all glass construction, you can actually give it a pretty good clean by just using hot soapy water.
We recommend doing this sooner rather than later after making a brew.
Because as the coffee oils, when left for a period of time can actually then become difficult to clean off, and may require a scrub, which is when cleaning a Chemex becomes more difficult than it needs to be.
When you are in a rush or just feeling a little lazy, then the Chemex is also dishwasher safe, just ensure you remove its handle and store safely in the dishwasher as glass can break.
Conclusion: What is the chemex coffee maker
Overall the Chemex coffee maker is highly recommended to all types of coffee brewers, and is a great accessory to have at home to change up your Specialty Coffee brewing methods and skills.
With the added help of a kettle and digital scales, you will be brewing up a quality intricate cup of Specialty Coffee, all from the comfort of your home.
So you are looking to make a good cup of Specialty coffee? Then the Chemex will deliver. What are you waiting for? Do you have a Chemex Coffee Maker?
