Chemex Step By Step Guide

Chemex Step By Step GuideInvented by a chemist in 1941, the Chemex Coffee Maker is simple in appearance and in use but is extraordinary engineered to brew the best cup of coffee possible. It is one of a few pour-over coffee brewing strategies which use a low-tech and basic procedure that are usually perfect for home brewing. The Chemex consists of a narrow-waist glass flask and uses proprietary paper filters.

The process to brew the coffee is very simple. Use these steps, tips, and techniques to brew up the perfect batch.

How to brew coffee by using chemex:

  • Place filter in Chemex making sure the three-layered side is towards the pouring spout. Rinse with hot water to remove the paper taste from the filter and to preheat the brewer. Generously cover the lower portions of the paper where the infusion takes place.
  • Pour your ground coffee into the filter and give it a gentle shake. This will flatten the bed, allowing for a more even pour.
  • Check your water temp, and slowly pour water directly into the crater making sure there are no pockets of dry coffee. This is the bloom. Wait about 30 seconds for all the grounds to become evenly wet. A solid bloom will ensure even water dispersion and a delicious cup later on
  • Slowly pour the remainder of your of water in a slow, circular motion, moving outward from the center. Total brewing time will about 2½ minutes.
  • Grab the filter paper by its top edges, lifting it up and out, grinds and all. Discard or save the spent grounds for your home garden compost.
  • Drink your coffee. Marvel at your dedication and skill.


  • Like all coffee preparation, the grind is important. If you are using pre-ground coffee, “regular” grind (the kind made for the old perculator pots) works much better than the “automatic drip” grind made for modern coffee makers.
  • Use a finger or utensil to create a small crater in the grounds to pour the coffee into.
  • Never pour water directly on the edges or onto the filter paper.
  • If you go over brewing try adjusting your grind coarser, or vice versa if you go under.
  • Use some boiled water to preheat your coffee cups, like the coffee shops do. This makes sure your coffee doesn’t drop a couple of degrees when you pour it into the cup.
  • With this apparatus, you can make coffee as strong as you like without bitterness.
  • Because of its purity, the resulting extractions can be covered and stored in the refrigerator for reheating…without losing flavor!
