Chemex Brew Guide

The Chemex Brew Guide: Compare Chemex recipes from top roasters!

This is the last Chemex brew guide you’ll ever need.

The Chemex is one of our favorite coffee brewers because it’s easy to use, environmentally friendly, and makes an excellent tasting cup. Once you have your basic pouring technique down (basically just don’t fill it all the way up so the coffee is stuck to the sides of the filter, keep it all as low as possible), the tricky part is dialing in the variables to match your own taste preferences. To help you, we’ve compiled this list of Chemex recipes from top roasters (and coffee subscription competitors).  :)

Basically everyone agrees on a 0:30-0:45 bloom, water temp in the range of 195-205℉, and a grind that’s slightly coarser than average for a pourover (because the thick filters drain a little slower).

The remaining variables are brew time and brew ratio. Here are how other brew guides compare:

Roaster Coffee (grams) Water (grams) Time
Blue Bottle 50-60g 600-700g 4:00
Intelligentsia 33g 525g 5:00
Stumptown Coffee 42g 700g 4:00
Sightglass Coffee 40g 600g 4:00
Craft Coffee 36g 600g 3:30
Mistobox 38g 600g 4:30
Ritual 45g 700g 4:30
Coava 40g 600g 3:45
Average 41g 621g 4:09

The table above measures water in grams because it’s generally best to weigh your Chemex on a scale as you brew it, to keep measurements as accurate as possible. If you don’t measure water in grams, you can go in fluid oz instead.

To convert, 20 oz = 591 grams.

You’ll also notice your Chemex has a little glass bump on it. That bump marks the half-full line, but it can also tell you how much coffee you’ve brewed. Here’s the bump volume based on Chemex size:

Chemex Size Bump Volume Grams
3-cup Chemex 7.5oz 212g
6-cup Chemex 15oz 425g
8-cup Chemex 20oz 567g
10-cup Chemex 25oz 709g

That should be all the info you need to get moving in the right direction. Enjoy a delicious Chemex!
