Chemex Brew Guide: How to make coffee in Chemex

 

  1. Grind your coffee beans

With coffee brewing, your coffee will always taste the best if your coffee beans have been grained just freshly before brewing. So get yourself a professional coffee grinder from our collection, fo example Comandante Hand Grinder significant for its consistent grind and alluring design. 

Now, the amount of coffee and water you're going to be using depends on how much coffee you want to make and how strong you want your Chemex coffee to be.

We suggest using a Chemex ratio 1:15 coffee to water. Which means that once you're using 50 grams of coffee, you'll need 750 ml of water. Once again, you can change the ratio depending on how strong you want you Chemex coffee to be.

  1. Set up the Chemex filter

Before actual brewing, you have to set up your equipment, starting with folding your Chemex filter and placing it 3-layered side in the front, one layer in the back of your Chemex spout. Once the filter is in place, pour water that you boiled before, and now should be just below 100 degrees, over the filter.

You do this to get rid of papery taste that may ruin your coffee and also to assure that the temperature of your equipment is consistent throughout the brewing. Pour the leftover water out and you're ready to start brewing.

  1. Start pouring to bloom the coffee (00.00-00.30)

Put the freshly ground coffee into the centre of the Chemex filter, start the timer and slowly pour hot water over the coffee in the circular motion, avoiding the paper filter and the centre of the coffee grounds. 

Once you hit 70 grams on the scale, which should happen within the first 5 seconds, you stop pouring and let the coffee bloom for 30, max 45 seconds. Blooming is the process in which coffee is being saturated and you can see that from the expanding coffee grounds or bubbles appearing.

  1. Pour more water (00.30-01.30)

After the bloom is finished, pour more water on the coffee grounds, once again in the circular motion, until you hit about 250 grams on the scale and total of one minute in the timer. While pouring, make sure you keep the water level below the top of the Chemex.

Afterwards, wait for all the water to soak through the coffee grounds until you finish the pour. This should take about 30 seconds again.

  1. Finish the pour (01.30-3.30)

After the water soaked through the coffee, pour the rest of the water in concentric circles and in the centre of the coffee until you hit 750 grams on the scale and you used all your water. 

Let all the water drip through the coffee grounds. The Chemex timing for a perfect brew is 3 minutes 30 seconds, but it may vary, depending on the grind coarse or the amounts you used.

  1. Your Chemex Coffee is complete!

You'll know that your Chemex coffee is ready once you see no dripping coffee from the bottom of the filter. Remove the coffee filter from the Chemex spout and enjoy your freshly brewed cup of delicious coffee!

To speed up the process, you may also skip step 4., and pour all the remaining water at once and just wait for the drip to finish. But this is, however, only good with smaller amounts of coffee and water.

Chemex brewing instructions vary throughout the guides because everybody prefers different intensity of their coffee. It also depends on the size of your Chemex and the number of cups you want to brew. How to brew coffee in a Chemex may be seemingly confusing, but believe us when we say that once you try it, you will love the process.

 

Frequently asked questions about Brewing in a Chemex

What coffee to use for Chemex?

The coffee beans you use for the Chemex brewing really depend on your preference, whether you like more chocolaty tones or fruity ones. We recommend the light roasted filter coffees that you can find out our specialty coffee subscription. 

But when it comes to grinding, the best coffee for Chemex is a medium-coarse grind, which will ensure that you brew a well balanced clean cup of coffee with maintained tones.

How to make strong coffee in Chemex?

The easiest way to ensure that your Chemex coffee is stronger in intensity is by changing the ratio on the brew. Of course, you want to avoid drastic changes that may ruin your coffee taste! But for example, adjusting the ratio from 1:15 to 1:13 should do no harm to the coffee taste and aroma. 

Also, you may just ask for coffee beans with higher intensity, perhaps you can try a slightly darker roast profile - espresso profile - that you can find in our selection

How to fold the Chemex filter?

There are two types of Chemex coffee filters - rounded and squared. It doesn't really matter which type you're using, you always want to fold your filters two times in half and then place it with the three layers towards the front of the Chemex spout and the side of one layer to the back. This will prevent any water to leak or the filter to collapse during the pour.

Are Chemex filters compostable?

As long as you're buying proper Chemex filters, they are all biodegradable. Although, while composting the paper filters you have to remember that the composting of paper takes longer, so you want to tear the filters into smaller pieces if you want to speed up the composting process.

What's the difference between Chemex vs. V60?

The process of making coffee in Chemex and Hario V60 pour-over is very similar, but there are few crucial differences. 

The may difference is that Chemex allows you to use bigger amounts of coffee and water for the brewing, but the process also takes longer. This also results in more bitter notes of the coffee, which is caused by longer contact between the coffee and water.

So once again, it depends on what coffee do you prefer, The pour-over coffee will result in smoother and more acidic taste, while Chemex gives you more bitter coffee taste. If you want to know a more specific description of the equipment, read through some of the Chemex reviews. It may give you a better overview before settling down for one method over the other. 

How do you make iced coffee in a Chemex?

If it's hot summer and you'd prefer iced coffee, it's really easy to brew one with Chemex. Follow the same recipe as for regular Chemex brew, except after rinsing your paper filter and throwing out the water waste, add some ice on the bottom of your Chemex and brew the coffee over the ice. Grind the beans slightly finer and use half the amount of water. The ather half should be the ice. So while the ice melts it will dilute your final beverage.
