Chemex Brewing Ideas

What you need: 

Chemex 

Filter

Ground Coffee

Kettle (preferable gooseneck) 

Timer 

Gram Scale 

 

Brewing Information: 

Grind: medium-coarse

Starting ratio: 1:15 (coffee to water) 

Time: 4 minutes

 

Method 1: 

1. Start by placing your filter into the Chemex. Rinse it with hot water (195℉-203℉), then drain, keeping the filter in place.

2. Place 20g of coffee into your filter. Tare your scale to 0g and start your timer.

3. Pour 50g of water over the grounds, just wetting them all.  This is called the bloom.  Let the coffee bloom and expand a bit for about 30-45 seconds before continuing your brew.  This allows the coffee to release some gases before you continue to saturate the grounds.  

4. Now, pour 50g of water every 30 seconds until you reach 300g. Try to pour away from the walls of the filter and use the same circular motion each pour.  Each pour should last about 10 seconds (5g per second), followed by 20 seconds before the next pour.  

5. Your coffee should finish around 4 minutes. 

6. Compost your grounds and filter

7. Enjoy your coffee!

4. Then pour about 75g of coffee in a circular motion and agitate (stir gently without hitting the sides of the Chemex). Continue adding water in the same circular motion to the line you previously reached until your desired weight.  Agitate once more after you have added all your desired water.  

5. Your coffee should finish around 4 minutes. 

6. Compost your grounds and filter

7. Enjoy your coffee! 

 

Things to try:

This can be a good method if you’re making coffee for someone who likes mellower coffee, or needs low acidity. For this try a ratio of 1:16 or 17.

Try adjusting the time for your bloom. If it reaches a point where it’s deflated, but does not yet look dry, it has done its job. 

How does the flavor change if you increase the amount of ground coffee while keeping the rest of the recipe the same? Do you like a ratio of 1:13?

Making coffee for multiple people? Try a slightly courser grind size and more coffee.  

 

Be sure to:

Either try to rinse the Chemex well with hot water immediately after use, or consider investing in a bottle brush (if not both). 

This is the only coffee brewer on permanent display at the MoMa. The goal of its inventor was to merge design and function. It’s also a good way to get a low-acid cup that can highlight the delicate qualities in your coffee. This is due in part to the fancy-looking filters, which are thicker than others. 

 

True to form the handsome look of the filters is related to how they work. Rather than unfolding, the filter simply separates so that three ply goes on one side, and one ply to the other. The thicker side goes toward the spout. The spout is designed to release air from the basin so that water can brew through the coffee into it. The three-ply side of the filter provides structure, so that it doesn’t collapse into the spout and prevent brewing.
